BROWN SPOTS CARE AND SOLUTIONS


Most of us usually struggle with some kind of brown or ashen pigmentation problem, regardless of your ethnic background or skin color. Skin will either appear lighter or darker than normal in concentrated areas, or you may notice blotchy, uneven patches of brown to gray discoloration or freckling.

Brown Spots: Causes & Solutions!

Skin pigmentation problems only occur because the body produces either too much or too little melanin. Melanin is the pigment in skin produced by specific cells (melanocytes). It is triggered by an enzyme called tyrosinase, which creates the color of our skin, eyes, and hair. This faulty melanin production is primarily caused by chronic unprotected sun exposure or hormones (particularly during pregnancy or from taking birth control pills).
As far as skin is concerned, depending on how much is present, melanin does provide some amount of sun protection by absorbing the sun's ultraviolet light. This explains why darker skin colors are less susceptible to sunburn and the overall effects of sun damage. But less susceptible doesn't mean immune from problems.

What to Do? Start with Sunscreen!

Store shelves are lined with products claiming to lighten skin. But without question, the first line of defense is smart sun behavior (meaning avoidance or, at the very least, careful exposure) along with the daily use (365 days a year) and liberal application (and, when needed, reapplication) of a well-formulated sunscreen. Diligent use of a sunscreen alone allows some repair as well as protection from further sun damage, which is what created the problem in the first place.
No other aspect of controlling or reducing skin discolorations is as important as being careful about exposing your skin to the sun and the use of sunscreen, SPF 25 or greater (and greater is usually better), with the UVA-protecting ingredients of titanium dioxide, zinc oxide, avobenzone, Mexoryl SX, or Tinosorb. Using effective skin-lightening products, exfoliants, peels or laser treatments without also using a sunscreen will prove to be a waste of time and money. Sun exposure is one of the primary causes of the skin discoloration disorder melasma, and other treatments can't keep up with the sun's daily assault on the skin. Before you look at any other option for brown or ashen skin discolorations, start with applying sunscreen and reducing sun exposure.

It Takes a Village

While sunscreen and avoiding direct sun exposure is essential, inhibiting increased melanin production stimulated by long term sun damage is equally important. There are many options to consider when searching for a solution. The most successful treatments use a combination of topical lotions or gels containing melanin-inhibiting ingredients along with a well-formulated sunscreen, and a prescription retinoid (such as Renova or generic versions containing tretinoin, a type of retinoid). Depending on how the skin responds to these treatments, exfoliants—either in the form of topical skin-care products or chemical peels done by a physician or lasers or intense pulsed light treatments can definitely enhance results.

Topical Treatments

Topical hydroquinone is a key step in reducing or eliminating skin discolorations. In fact, topical application of hydroquinone is considered by many dermatologists and extensive research to be a safe and effective treatment for skin discolorations. Topical hydroquinone in 2% concentrations from cosmetic companies and 4% concentrations available from a physician or by prescription should definitely be a consideration. For more information about hydroquinone.

Some research has shown topical azelaic acid in 15% to 20% concentrations to be as efficacious as hydroquinone with a decreased risk of irritation. Tretinoin by itself has also been shown to be especially useful in treating hyperpigmentation of sun-damaged skin. Kojic acid, alone or in combination with glycolic acid or hydroquinone, also has shown good results due to its inhibitory action on tyrosinase (though kojic acid has had its share of problems in terms of stability and potential negative effects on the skin and is rarely being used nowadays). Several plant extracts and vitamin C also have some research showing them to be effective for inhibiting melanin production, but hydroquinone has the most impressive amount of research overall.

Alpha Hydroxy Acids

Alpha hydroxy acids (AHAs)—primarily in the form of lactic acid and glycolic acid—are the most researched forms of AHAs because they have a molecular size that allows effective penetration into the top layers of skin. It is generally assumed that in and of themselves AHAs in concentrations of 4% to 15% are not effective for inhibiting melanin production and won't lighten skin discolorations in that manner. Rather, it is believed that their benefit is in helping cell turnover rates and removing unhealthy or abnormal layers of superficial skin cells (exfoliation) where hyperpigmented cells can accumulate. However, other research has shown that lactic and glycolic acids can indeed inhibit melanin production separate from their actions as an exfoliant on skin.
Either way, there is a good amount of evidence that in combination with other treatments—such as hydroquinone, tretinoin, and, of course, an effective sunscreen—AHAs can be very effective for improving the overall appearance of sun-damaged skin and possibly helping other ingredients penetrate skin better. While there is no comparative research in regards to salicylic acid (BHA) and its effect on melasma, it makes sense to assume that because salicylic acid exerts a similar action on skin as AHAs, it will have similar results for improving skin color.

Laser Treatments

Both ablative and nonablative lasers and light treatments administered by a dermatologist can have a profound improvement on melasma. However, the results are not always consistent, and problems can occur (such as hypo- or hyperpigmentation). Moreover, laser treatments of this kind often are a problem for those with darker skin tones. Nonetheless, when laser treatments work they can have a marked difference in the skin's appearance, especially when used in combination with the other topical treatments previously mentioned. The results can be startling, and though expensive, for stubborn discolorations, lasers are absolutely worth a try. There are many types of lasers that can be successful for this purpose. Which one is optimal for you is best determined by a skilled dermatologist who has a practice that incorporates a variety of different lasers and/or light-emitting devices.

How to Use Your Skin-Lightening Products

Seeing brown spots? Too many days in the sun or routine exposure to daylight can result in unsightly clusters of melanin (skin’s pigment) showing up on your face, neck, and chest—all areas routinely exposed to UV light. As frustrating as these brown spots are, there’s hope in the form of skin lighteners. The catch? You need to know how to add them to your daily routine, you need patience, and, most important, you need sun protection! Ahead, we reveal how to add a Paula’s Choice skin lightener (or lighteners) to your routine for great results—advice that also applies to skin lighteners from other brands!

What to Expect from a Skin Lightener

Of course, the obvious expected result from using a skin lightener is for the dark or brown spots to get lighter. And if they fade completely, that’s even better! With once- or twice-daily usage, you can reasonably expect a skin-lightening product containing proven ingredients to progressively lighten your dark spots.
Sadly, this lightening won’t happen overnight. It’s important to keep this in perspective; while we completely understand the desire to see those spots fade NOW, keep in mind that it took several years of ongoing daylight exposure for the spots to form and then show up. So, reason dictates these slow-to-form brown spots require patience and persistence as you wait for them to fade. Most of us will need to use a lightening product every day, morning and evening, for at least 3 months before significant results can be seen.
What you shouldn’t expect from a skin lightener is for it to work while you continue to expose your skin to UV light without sun protection or continue to tan. We’ll go into detail on this later in the article, but the key point is that no skin-lightening product can be that effective if you’re not willing to protect your skin daily from further UV damage. And if you want to keep tanning, a skin lightener won’t work at all. Sun protection (and, some dermatologists would stress, sun avoidance) is a key part of lightening brown spots and preventing new ones. This may sound harsh, but if you’re not willing to commit to daily sun protection no matter what, there’s no sense in using any skin-lightening products because you will be steadily undoing what they’re trying to fix.

The Best Skin-Lightening Ingredients

Now, there are only a handful of ingredients with impressive, substantiated research on their ability to lighten brown spots. They work in a variety of ways to interrupt the process that "fuels" these spots, which is one more reason you may need to use more than one skin lightener. Here are the tried-and-true ingredients to look for when shopping for a great skin-lightening product:
  • Hydroquinone (widely considered the gold standard)
  • Vitamin C (ascorbic acid and derivatives), when used in higher concentrations
  • Niacinamide
  • Licorice extract
  • Acetyl glucosamine
There are a few others to consider, and research is examining new options all the time, but to date, the ones listed above have the best track records and show up in a range of skin-lightening products—including those from Paula’s Choice!

Sunscreen is a Must

We touched on this above, and it bears repeating: No skin-lightening product will be of much use if you’re not willing to apply a broad spectrum sunscreen every day of the year, whether it’s cloudy or sunny, even if you’ll be indoors for most of the day. If you can see daylight, even if you’re in your home or office, it’s affecting your skin and keeping your brown spots from responding as well as they otherwise would to treatment. UVA rays—the kind that can trigger DNA damage in skin—can penetrate windows.
Scary fact: One bout of unprotected sun exposure can undo months of progress with a skin-lightening product. There’s simply no room for compromise here: Sun protection and skin lighteners are a package deal. When it comes to treating brown spots, one cannot work as well without the other— both play critical roles in lightening the brown spots you see now AND those you don’t want to see later!

You May Need More Than One Lightening Product

Even if you’re using one of the best skin-lightening products out there and being diligent about daily sun protection, your dark spots may not improve much, if at all. Why is this? Simply put, some discolorations are deeper in the skin and, as a result, much more stubborn or slow to respond to topical treatments. What to do? You can consider seeing a dermatologist for a series of light-emitting or laser treatments (these can help a lot), a prescription product with a higher amount of hydroquinone, or a series of chemical peels. But before you make an appointment, consider adding a second—or potentially a third—lightening product to your routine and see how your brown spots respond after several more weeks (sigh...see what we mean by 'patience is needed'?).
Research has shown that for some people, a combination of active skin lightening ingredients is needed for optimal results. Hydroquinone or vitamin C alone might not be enough. Here are some potential pairings of Paula’s Choice skin-lightening products should you determine you’d like (or need) to use more than one product to reduce or possibly eliminate your brown spots:
Resist Triple Action Dark Spot Eraser (hydroquinone) + Resist C15 Super Booster(15% vitamin C + other antioxidants)
Tip: Apply C15 first, after your AHA or BHA exfoliant, then follow with the Triple Action Dark Spot Eraser.
Resist Pure Radiance Skin Brightening Treatment (niacinamide, acetyl glucosamine, and licorice extract) + Resist Vitamin C Spot Treatment (25% ascorbic acid) or, for allover use, try the Power Couple of Resist C15 Super Booster and Pure Radiance Skin Brightening Treatment.
Tip: Apply the Skin Brightening Treatment all over (it makes a great primer, too!) and add the Vitamin C Spot Treatment to the dark spots.
Resist Triple Action Dark Spot Eraser (hydroquinone) + Clinical 1% Retinol Treatment (retinol in higher strengths can improve stubborn dark spots).
Tip: If your skin cannot tolerate a high-strength retinol product, try applying less often, such as twice per week, or mix with a few drops of Resist Moisture Renewal Oil Booster to enhance your skin’s tolerance.
Be sure your daily skincare routine includes products loaded with anti-aging ingredients that can play a supporting role in helping to make your skin tone look younger and more even.

Treating Sun Spots Below the Neck + Other Body Concerns

Reducing fine lines, wrinkles, and discolorations (not to mention restoring a healthy glow) are skin-care goals many people have. Yet many of us focus almost exclusively on skin from the neck up, not even trying to get the same benefits for skin elsewhere on our body.
The biggest signs of aging we see on our faces—brown discolorations, dryness, crepey skin, sagging—can appear on your arms, décolleté (chest), legs, and everywhere else, too. The good news is these concerns can be addressed by repairing past damage with a few targeted products whose prices won't break the bank.

The Best Anti-Aging Defense is a Good Offense

Consisitent use of a sunscreen is the most important thing you can do to slow the signs of aging—at any age—whether you're 16 or 66. One area we often neglect when applying our daily SPF-rated sunscreen is our hands, but our hands get at least as much UV exposure as our face! Brown sun spots and crepey skin on our hands are dead giveaways of sun-damage accumulated over decades—how many decades is a fact that many of us prefer not to broadcast. Consider Resist Ultimate Anti-Aging Hand Cream SPF 30, a rich cream that provides serious moisture, proven antioxidants, and a water-Resistant sunscreen that dries to a clear finish.

Solutions for Sun Spots Below the Neck

Keep your skin soft while targeting discolored areas with a daily exfoliant—but not a body scrub or loofah. Physical exfoliation will not lead to younger, more even-toned skin because it tears away at the skin, damaging collagen. Instead, use an AHA (glycolic acid) or BHA (salicylic acid) exfoliant to smooth and gently clear away dead skin, fade brown spots, stimulate collagen production, and soften dry, rough areas. Paula's Choice Resist Skin Revealing Body Lotion with 10% AHA is great for sun-damaged areas. If you also have breakouts or red bumps, go for Paula's Choice Resist Weightless Body Treatment with 2% BHA.

Retinol: Not Just for Your Face

Antioxidants and cell-communicating ingredients are among the superstars that keep skin healthier and younger. They accomplish this by warding off the free-radical damage that contributes to signs of aging, and retinol is one of the hardest workers of the bunch!
Anti-aging routines shouldn't neglect your body. Target the skin below your neck, especially chest and arms, with a retinol-infused body treatment like Paula's Choice Resist Retinol Skin-Smoothing Body Treatment. Retinol works best when paired with other beneficial ingredients—that's why Resist Retinol Body Treatment contains such ingredients as glycerin, shea butter, evening primrose oil, and antioxidants like vitamin C.

Ditch Your Skin-Damaging Habits

When youthful skin below the neck is the goal, what you avoid is just as important as the products you use! Preserve that healthy glow and smooth, even skin by breaking these bad habits:
  • Get yourself out of hot water. A steamy shower or bath may feel nice in the short-term, but doing it too often or soaking too long will result in alligator-like dry, damaged skin. High temperatures do a number on your skin's protective barrier, stealing the substances in the skin that keeps your healthy outer layers smooth and intact. Keep the water temperature warm, not hot, and don't linger in the bath or shower!
  • Fragrance = "Eau de Dermatitis." Many people select body-care products with their nose, but fragrance isn't skin care—far from it. Skip the fragrance if you want to keep your skin at its best, whether above or below the neck. From your head to your toes, find out why fragrance-free products are always the best choice.
  • Clean up your diet. Eating the wrong foods (or not enough of the right ones) plays a significant role in more than just our waistlines. Too much sugar or inflammation-promoters, such as overly processed foods, trans-fat, and red meat, create a free-radical buffet that contributes to (You guessed it!) signs of aging. Read up on the foods to look for (and what to cut out) for healthier, younger-looking skin.

The Bottom Line (for More than Just Your Bottom)

Anti-aging isn't just for your face—keeping the skin below your neck smoother, firmer, and more even-toned is as easy as picking the right products and treatments. Stick to recommended products that do more, like those loaded with innovative ingredients, and don't forget the sunscreen! Keeping from the neck down, protected from daily sun damage is the #1 most important thing you can do to ensure smooth, healthy, spot-free, and—OK, we'll say it—sexy skin.

                       Hydroquinone for Skin Lightening 

History has it that hydroquinone has become a controversial skin-care ingredient for topical use. What is known for certain is that hydroquinone is a strong inhibitor of melanin production and for over 50 years has been established as the most effective ingredient for reducing and potentially eliminating brown skin discolorations on skin often referred to as melasma.

Concentration Counts!

In different concentrations hydroquinone inhibits or prevents skin from making the enzyme responsible for triggering melanin, the chief pigment that gives skin its color (Source: Journal of Drugs in Dermatology, March 2010, pages 215-218). Over-the-counter hydroquinone products can contain 0.5% to 2% concentrations, with 2% being the most effective OTC amount. At the pharmacy, 4% concentrations of hydroquinone (and sometimes even higher) are available by prescription only. A concentration of 12% hydroquinone actually prevents the production of melanin altogether.

Misinformation Breeds Confusion

What is confusing to the consumer is the exaggerated information about possible negative side effects from using hydroquinone products. Yet a closer look at the research indicates problematic skin reactions are rare and, more often than not, minor. The most startling risk is a skin disorder called ochronosis which is a bluing discoloration of the skin. Although that's scary stuff, it's important to keep in mind that with millions of gallons of hydroquinone used over the past 50 years, only a handful of ochronosis cases have been directly associated to using hydroquinone. What's more, these cases have been a result of long term use of high concentrations, or of using hydroquinone products that have been adulterated with dangerous ingredients (Sources: Journal of the European Academy of Dermatology and Venereology, July 2009, pages 741-750; and Journal of the American Academy of Dermatology, November 2007, pages 854-872).

The Hydroquinone Ban Should Be Lifted!

Hydroquinone-based products were banned in South Africa years ago where the most severe problems occurred. However, hydroquinone products in South Africa and other African countries were found to also contain mercury and glucocorticoids, among other caustic and illegal contaminants, which is believed by many to be the cause of the serious side effects seen (Sources: International Journal of Dermatology, February 2005, pages 112–115; and British Journal of Dermatology, March 2003, pages 493–500). Countries that are part of the European Union have banned hydroquinone chiefly on the basis of these reports. This ban is frustrating to many because when properly formulated, hydroquinone is not a harmful ingredient and there's no substantiated research proving otherwise.

Is Hydroquinone Carcinogenic?

Questions concerning hydroquinone in terms of it being a carcinogen have also been addressed in the research. Problematic incidences have been shown when hydroquinone was fed or injected into rats in large doses, though with topical use there has been no research showing it to be mutagenic on humans or animals. In reality, there is abundant research showing hydroquinone to be safe and extremely effective
Interestingly, hydroquinone happens to be a potent antioxidant and there is even research showing that workers who handle pure hydroquinone actually have lower incidences of cancer than the population as a whole.

Natural Alternatives to Hydroquinone

Ironically, plant extracts such as Mitracarpus scaber (madder) extract, Uva ursi (bearberry) extract, Morus bombycis (mulberry), Morus alba (white mulberry), and Broussonetia papyrifera (paper mulberry) touted as being natural skin lightening agents actually break down into hydroquinone when absorbed into skin, which explains why they have a positive effect. Another natural alternative is arbutin which also, you guessed it, breaks down into hydroquinone in skin.
Whether or not you consider using hydroquinone in a skin-care product is of course up to you. What is abundantly clear is that hydroquinone is a well-researched ingredient, incredibly effective for its intended purpose, and that no other skin lightening ingredient compares to its effectiveness.

Hydroquinone Hates Air!

One critical point to keep in mind: hydroquinone can turn a strange shade of brown with prolonged, daily exposure to air or sunlight. When you are considering a hydroquinone product, it is essential to be sure it is packaged in a non-transparent container that doesn't let light in and that minimizes the amount of air exposure. Hydroquinone products packaged in jars are absolutely not recommended because once opened they quickly become ineffective.

Options Beyond Hydroquinone

For other potential options for skin lightening—though with far less research or impressive and consistent improvement—niacinamide, licorice extract (specifically glabridin), azelaic acid, and stabilized forms of vitamin C (L-ascorbic acid, ascorbic acid, and magnesium ascorbyl phosphate) can also be considered. There is also no research showing exactly how much of each ingredient is needed to achieve results so you have to trust the cosmetic company making the claims, and we all know how reliable that is! Still, some companies, such as Procter & Gamble (P&G, owner of brands such as Olay and DDF) are amassing an impressive body of research concerning skin lightening ingredients that rival the effectiveness of hydroquinone.

How to Use Over-the-Counter & Prescription Retinol Products

Retinol (more commonly known as Vitamin A) is great for your skin, no question. But because there are several forms of retinol it is hard to know which one to use. Should you try over-the-counter retinol or ask your dermatologist about prescription retinol (retinoid) products? And how does it fit in with your skin-care routine? 

What is Retinol?

Retinol is just another simple name for the entire vitamin A molecule. It is considered a cosmetic ingredient and found only in non-prescription products (mostly skin care). Retinol can be broken down to become other forms of vitamin A that are found in skin-care products or prescription products.
An example of a cosmetic form of retinol in skin care products is retinyl palmitate. Generally, pure retinol is considered more effective than retinol derivatives.
Prescription retinol products such as Renova and Retin-A contain the active ingredient tretinoin. Tretinoin is far more potent than retinol, but comes with a higher chance of irritation.

Why is Retinol Good for the Skin?

Whether in over-the-counter or prescription form, vitamin A in all its forms works as a cell-communicating ingredient. That means it can actually tell a skin cell to behave and even look like a more normal, younger cell. When you have sun damaged skin this communication is incredibly beneficial because sun damaged skin produces unhealthy, abnormal, and inflexible skin cells.
When dermatologists discuss "prescription retinol", they're referring to various forms of vitamin A that can only be used in prescription medications. Renova or Retin-A are the best known prescription forms of retinol containing the most "active" form called tretinoin (also known as all trans retinoic acid or retinoic acid). We know all of these terms can be confusing, but this list should help make things easier to understand:
  • Retin-A has a lightweight cream texture and is most often prescribed for acne.
  • Retin-A Micro has a gel texture with a matte finish that's best for oily, acne-prone skin
  • Renova has an emollient texture and is prescribed for wrinkles/sun damage.
  • Tri-Luma contains tretinoin along with prescription-strength hydroquinone and is prescribed for discolorations and melasma. Note: Because the steroid this contains may cause skin thinning with prolonged use, short-term usage of this product is advised.
  • Atralin, Avita, Altinac, Refissa, and Tretin-X are other prescription-only products with tretinoin.
  • Tretinoin is also available as a generic that is just as effective as brand name versions.
Regardless of brand or texture, tretinoin fights wrinkles, uneven skin tone, and breakouts. Which one to use should be based on your physician's recommendation and, to some extent, your personal preference.

Other Prescription Forms of Retinol (Retinoids)

Beyond the active ingredient tretinoin found in the prescription-only products mentioned above, the two other most common prescription forms of vitamin A/retinol are Differin, which contains adapalene, and Tazorac, which contain tazarotene.
Both of these are typically prescribed for acne. Neither has as much anti-wrinkle research as tretinoin but theoretically both should provide similar antiaging benefits. Generally, Differin is worth considering if you have acne but your skin cannot tolerate prescription retinoid products.

Is Prescription Retinol Better for Me?

Retinol in all its forms, over the counter or prescription-only, is excellent for preventing and improving signs of aging. But in order for the over-the-counter (cosmetic) version of the entire vitamin A/retinol molecule to be effective it must break down into the active form (tretinoin) found in prescription vitamin A products.
Keep these facts in mind to help you determine which form is best for your needs:
  • Prescription-strength forms of retinol are "stronger" and work faster. Cosmetic retinol takes longer to have an effect but in the long run it works the same.
  • Prescription-strength forms of vitamin A/retinol (tretinoin) present a greater a risk of causing irritation. For some people the irritation never goes away and they can't use it.
  • Cosmetic retinol has a far lower risk of causing irritation but because it is still breaking down in your skin to become the active prescription form (tretinoin) it can also be irritating.
  • It takes experimenting to see which frequency of application works best for you; many find that using retinol 2–3 times per week works great while others can use it every day.

Can I Use AHA or BHA if I'm Using a Prescription or Cosmetic Retinol Product?

A common misperception about retinol is that it exfoliates your skin. Vitamin A/retinol in any of its forms does not do the same thing as AHAs or BHA. AHAs and BHA exfoliate the surface layers of dead built-up skin, improving sun damaged or genetically thickened skin cells.
Whether over-the-counter or prescription form, retinol is a cell-communicating ingredient that "tells" skin cells to make healthier, younger cells and can enhance the production of new skin cells. It is not an exfoliant.
Where it gets confusing is because retinol in both over-the-counter and prescription products can cause flaking. Because of this side effect, people assume it is also exfoliating their skin. Flaking skin is not exfoliation. AHAs and BHA help skin do what it should be doing naturally, and naturally you don't see your healthy skin cells shed. Instead, you just see a smooth, renewed skin surface and a healthy glow.
For the best anti-aging, anti-wrinkle benefit it is ideal to use both an exfoliant and a vitamin A/retinol product. PS: If you've heard that you can't use retinol with vitamin C (or AHA & BHA exfoliants) due to claims the ingredients deactivate one another, not to worry, this isn't accurate in the least. Check out our myth-busting article on this very topic for more details.

How to Use Your Prescription Retinol (Retinoid) Product

Here is how to use a prescription retinol product (with the active ingredient *tretinoin) with your daily skin-care routine:
  1. Cleanse, tone, and exfoliate your skin with your AHA or BHA product as usual.
  2. Next, apply the prescription product.
  3. If you're using a skin lightening product too, apply it after the prescription retinoid.
  4. Proceed with your moisturizer and/or serum, which can also be applied around your eyes.
More Tips:
  • To help your skin get used to prescription-strength retinol, apply every other day, always at night (sunlight deactivates the active ingredient).
  • If your skin tolerates it you can then gradually move up to once daily application, but always at night.
  • Keep in mind that more is not better; only a pea-sized dab is needed for your entire face!
  • It is OK to apply tretinoin (the main prescription retinoid) at the same time as benzoyl peroxide.

What Else You Need to Know:

  • Retinol products may be applied underneath the eye, but not on the eyelids or underbrow area.
  • It is OK to use an over-the-counter retinol product with a prescription retinol product. Which one to apply first is up to you.
  • If you notice signs of irritation (flaking, redness, sensitivity) do not double up on retinol products and/or decrease frequency of application.
Important note: whether you choose an over-the-counter or prescription retinol product, daily use of a well formulated sunscreen rated SPF 25 or greater is a must! Even the most effective, research-proven antiaging ingredients won't work like you want them to if you're not diligent about sun protection. After all, sun damage created most of what you're using antiaging products to improve!
For best results, any form of vitamin A/retinol should be used with other anti-aging products containing rejuvenating ingredients such as antioxidants, skin-repairing ingredients, and different cell-communicating ingredients such as niacinamide. Despite retinol's superstar status, treating signs of aging is far more complex than any one ingredient can address!

How Does Vitamin C Help Skin?

If you have really shopped the skincare aisle lately (or in the last decade), you know that there is no shortage of anti-aging ingredients on the market. Despite the marketing hype often assigned to a single ingredient, research is clear that using a range of beneficial ingredients is always best for keeping skin at its healthiest. There are some exceptions—standout ingredients that, whether included among a mix of beneficial ingredients or in a concentrated treatment, are among a select few that can treat multiple skincare concerns. Vitamin C is one such example!
Here, we’ll share the research-proven results you should expect from vitamin C, we’ll discuss whether one form is better than another, and share how you can incorporate this powerhouse antioxidant into your skincare routine.

Vitamin C for Anti-Aging & Brighter, Healthier Skin

In any form (and we’ll get to which types work best), vitamin C provides potent antioxidant protection, shielding skin from damaging free radicals—those pesky rogue molecules that promote premature aging. The most abundant forms of free-radical damage are environmental factors we can’t escape—think sun damage, pollution and oxygen—that assault skin on a daily basis, but that’s where topical vitamin C can help.
When incorporated into your daily skincare lineup, well-formulated products containing vitamin C can provide a range of benefits that keep your skin younger-looking, longer! See what C can do:
  • Reduce the appearance of brown spots and other types of sun damage
  • Helps boost healthy collagen production (hello, firmer skin!)
  • Reduce inflammation and irritation, both of which cause a cascade of damage
  • Fade post-breakout red marks by improving skin’s natural healing response
  • Increase the effectiveness of your sunscreens and boosts your skins defense against UV exposure

Ascorbic Acid: Vitamin C Royalty

Ascorbic acid—also known as L-ascorbic acid—has the most research of any form of vitamin C when it comes to benefits for skin. For that reason, ascorbic acid is the most form of vitamin C used in well formulated skincare products. When properly formulated, it helps create younger, firmer skin while fading signs of sun damage and post-acne marks.
Ascorbic acid is also a powerhouse when mixed with other antioxidants, or when used alone in higher concentrations, such as 15% or 20% or greater, amounts that can be great for treating extra-stubborn concerns.
Recommended Treatments: Add a few drops of Paula’s Choice Resist C15 Super Booster—a 15% ascorbic acid + peptide treatment—to your favorite serum or moisturizer for dramatically brighter, firmer and healthier skin.
Want to target a particularly stubborn brown spot, red mark or wrinkle? Dab a small amount of the Paula’s Choice Resist Vitamin C Spot Treatment, a 25% ascorbic acid concentrate, to the bothersome area and watch them beat a hasty retreat.

Vitamin C: The Extended Family

Good news: There isn’t a single “best” form of vitamin C, but there are only a handful that research has demonstrated are the most stable and effective. Other effective forms include sodium ascorbyl phosphate, ascorbyl palmitate, retinyl ascorbate, tetrahexyldecyl ascorbate and magnesium ascorbyl phosphate—each derivatives of vitamin C, but all with less supporting research than ascorbic acid (but what research does exist is certainly encouraging).
Each of these forms of vitamin C has a range of benefits that include repair and protection from free- radical damage; the takeaway is that these are more beneficial when added to a blend with other proven antioxidants and cell-communicating ingredients. Look for products that include these with ingredients such as green tea, ascorbic acid, retinol, and/or niacinamide.
Note: All antioxidants, including vitamin C, are vulnerable to destabilizing when exposed to air and light (Skin Research and Technology, 2008). That means if you want to reap the reward of your antioxidant-enriched treatments, only choose those that are packaged in opaque tubes, air-restrictive bottles, or pumps that help keep their ingredients stable!
Recommended Treatments: You’ll find multiple forms of vitamin C in many Paula’s Choice products. Get even more information on how adding a serum or retinol treatment that contains a proven mix of vitamin C and other beneficial ingredients can help improve the anti-aging results of your skincare routine!

Bottom Line

With millions of research around its benefits, vitamin C is a long-established skincare superstar that can help you achieve younger, healthier and more radiant skin. However, like any ingredient, skincare will never be as simple as any single ingredient—just as no single food or nutrient can keep your body healthy, you need more than just one ingredient to keep your skin in good shape, too!
It’s important to mention that vitamin C forms are effective in lower concentrations, so don’t get caught up in the belief that only higher strengths are beneficial for skin. Research has shown that concentrations as low 0.6% provide antioxidant and anti-aging benefits to skin (Skin Research and Technology, 2008). Depending on your concerns, you may do just fine using a regular-strength vitamin C product, especially is said product also contains a range of great ingredients to smooth, repair, and replenish skin.
Without question, vitamin C is a powerful tool in your anti-aging arsenal. For best results, use it strategically and as part of a routine that includes a daily broad-spectrum sunscreen plus irritant-free products that contain a skin-pleasing mix of antioxidants, skin-repairing agents, and cell-communicating ingredients.

How to Exfoliate Skin

Without question, everyone can benefit from daily use of a well formulated AHA (alpha hydroxy acid such as glycolic and lactic acids) or BHA (beta hydroxy acid, also known as salicylic acid) product. Each provides multiple benefits, including fighting signs of aging and breakouts.

How Exfoliation Works

Skin naturally sheds billions of skin cells each day. When this natural shedding slows or stops due to sun damage, dry skin, oily skin, genetics, or different skin disorders, the results are unmistakable: dull, dry, or flaky skin; clogged pores; blemishes; white bumps; and uneven skin tone. Using an exfoliant steps in to help put everything in balance again. When you gently get rid of built-up skin cells you can undo clogged pores, stop breakouts, smooth out wrinkles, even make dry skin become a thing of the past!

Exfoliating Can Make You Look Instantly Younger

How is that possible? Think about it in comparison to the skin on your heels before you get a pedicure. The built-up, dead layers of skin on your heels usually looks dry, rough, discolored, scaly, and lines are really obvious. Once that layer is removed, your heels immediately look smooth and unwrinkled! Of course, what causes calluses on your feet is different than what causes skin cells to build up on your face, but the same benefit of exfoliating heels holds true for your face; you just have to be far gentler. With well formulated AHA or BHA exfoliants, that's easy to do!

What's The Difference Between AHA and BHA Exfoliants?

Great question! When properly formulated, both AHAs and BHA are brilliant options for exfoliating the surface of skin. Both AHA and BHA work to reduce wrinkles, stimulate collagen, and firm skin but each has its special qualities you'll want to consider when deciding which one to use:
  • AHAs are preferred for sun-damaged and dry skin because they exfoliate on the surface of skin and have the added benefit of also improving moisture content.
  • BHA is preferred for oily, acne-prone skin and for treating blackheads and white bumps because BHA can get through the oil that's clogging your pores, normalizing the lining of the misshapen pore that contributes to acne.
  • BHA has anti-inflammatory and antibacterial action. Those are two more reasons to use a BHA exfoliant if you have acne or sensitive, reddened skin.
  • BHA is preferred for those struggling with rosacea. Not everyone with rosacea can tolerate an exfoliant, but it is wise to experiment with a BHA product to see how your rosacea responds. It is quite likely you'll see less redness and a smoother, more even skin with fewer breakouts.
If your skin is sun-damaged and you're also struggling with acne or clogged pores, add a BHA product to your routine. If you'd like to use an AHA and BHA at the same time, that is an option, though not really necessary. Some people find they work well when they're applied at the same time, but if you want to give this a try it is best to apply them separately, one during the day and one in the evening.

How Do I Use an AHA or BHA Exfoliant?

  • You can apply an AHA or BHA product once or twice a day.
  • You can also apply either of these around the eye area but not on the eyelid or directly under the eye.
  • Apply the AHA or BHA product after your face is cleansed and after your toner has dried.
  • Once the AHA or BHA has been absorbed, you can apply any other product in your routine, such as moisturizer, serum, eye cream, sunscreen, and/or foundation.
  • If you're using a topical prescription product such as Renova, other retinoids, or any of the topical prescription products for rosacea, apply the BHA or AHA first.
  • The Paula's Choice Research Team's complete list of the best AHA and BHA products is available on Beautypedia.

Should I Use a Scrub to Exfoliate?

Scrubs are certainly an option for exfoliating your skin, but they have limitations you don't have to worry about with an AHA or BHA exfoliant. Scrubs only deal with the very top, superficial layer of skin while most of the unhealthy, built-up skin cells are beyond the reach of a scrub. What is most problematic is that many scrubs have a rough, coarse, uneven texture that can cause skin damage by tearing into the skin as it abrades away the surface, causing tiny tears that damage the skin's barrier. Scrubs often cause more problems than they could possibly solve.
If you do want to use a manual scrub, you can simply use a gentle washcloth with your daily cleanser, which works just as well to exfoliate the surface of skin as any cosmetic scrub you can buy. As a bonus, washcloths are softer (thus gentler) and of course they don't contain pore-clogging ingredients that oily, acne-prone skin doesn't need.

Is it Possible to Exfoliate Too Often?

Exfoliating your skin is great, but how often to use one that works best for your skin type takes experimenting. It is possible to overdo it, and your skin will tell you if you've gone too far. For some people once a day works best, for others every other day, or once a week. However, exfoliating does not negatively affect how healthy skin cells are generated in the lower layers of skin. If anything, exfoliating unhealthy dead skin cells on the surface of skin can improve collagen production, increase skin's ability to hold moisture, and allow pores to function normally!

                         Chemical Peel As An Option.

Chemical peels has to do with applying a type of "chemical agent" to the skin for the purposes of exfoliating sun-damaged, thickened surface skin while stimulating collagen production for firmer skin. The popularity of chemical peels lessened when lasers became the accepted method for treating wrinkles and brown spots but in balance, depending on the amount of wrinkling present and desired results, chemical peels still play a significant role in skin resurfacing.

What Do Peels Contain?

Peel solutions most typically contain either alpha hydroxy acids (an AHA such as glycolic acid), beta hydroxy acid (salicylic acid, also known as BHA), tricholoracetic acid (TCA), or phenol as the exfoliating agent. Each of these are categorized by the concentration and the resulting depth of the peel on the skin which can range from superficial (also known as micro or light peels) to medium or deep peels. Results are closely linked to the depth of peel performed. Superficial peels (typically those using low concentrations of AHA or BHA) offer far less dramatic improvement than medium or deep peels (usually TCA or phenol-based) do. Overall, you can expect minor to major improvement in fine lines and wrinkles, skin discolorations, skin texture, rebuilding of collagen, removal of blackheads, and a temporary reduction in excessive oil production.

What Can a Peel Do...and Not Do?

With any peel it is important to know what's possible so you can keep your expectations realistic and spare yourself disappointment. Chemical peels in any form cannot remove or reduce the appearance of blood vessels on the skin, they cannot change the appearance of enlarged pores, they do not have an effect on keloidal (raised) scarring, they do not work as a face-lift, and they have limited benefit for improving skin discoloration for those with darker skin color. They can make skin smoother, help fade brown spots and an uneven skin tone from sun damage, and generally make skin's surface look fresher and younger. Having peels done on a regular basis (say, every 6-8 weeks) will lead to collagen stimulation that improves the appearance of wrinkles.

There are definite drawbacks to consider with peels, but this is largely dependent on the type and depth of peel. Superficial peels have few associated risks but also offer less noticeable results. Some redness, swelling, and increased skin sensitivity can occur with superficial peels. You may also experience a period of intense flaking as the old, damaged skin is replaced by fresh, smooth new skin.

When significant results are desired, complications increase proportionately. Medium and deep peel complications can include scarring, infection, temporary or permanent changes in skin color (this is especially true for deeper peels), and cold sore breakouts for those with a history of cold sores. For these reasons, many cosmetic dermatologists are forgoing deeper peels in favor of what can be accomplished more safely with light-emitting and laser devices.

Chemical peels are performed by the application of the specific solution that actually dissolves the skin's top layers, either over the entire face or on specific areas. Often, several shallow to medium-depth peels can achieve similar results to one deep-peel treatment, with less post-procedure risk and a shorter recovery time. Talk to your dermatologist about this option and see if it may be the best approach to take.

AHA Peels

Alpha hydroxy acid (AHA) peels uses glycolic acid as the peeling ingredient and these are considered superficial to medium peels depending on the concentration utilized. Typically the concentrations range from 30% to 70%. AHA peels are effective in improving skin texture, causing some collagen and elastin rebuilding, minimally reducing the appearance of acne scarring, and reducing the appearance of skin discolorations. Repeated treatments are necessary for all concentrations to maintain results.

Important Note: AHA peels are not medical procedures and as a result are not regulated by the FDA. A physician usually performs higher-concentration peels (more than 30%), but this is not always the case. Lower-concentration peels (20% to 30%), often performed by aestheticians, require repeated treatments to achieve and maintain the results seen immediately after the peel is performed.
After any peel, the practitioner should apply a broad-spectrum sunscreen (preferably one whose only active ingredients are titanium dioxide or zinc oxide) to your skin. Skin will be sun-sensitive for a few weeks after the peel, and it makes sense to use sun protection to protect the investment you just made. Don't bother with peels if you insist on getting a tan, either from the sun or from a tanning bed. A reputable, ethical dermatologist would never offer a peel to someone who is visibly tan or cannot commit to daily sun protection.

BHA Peels

Beta hydroxy acid (BHA) or salicylic acid peels are not as popular as AHA peels, yet they can be equally effective and have specific advantages for some skin types. A salicylic acid solution can work in a way that is similar to a glycolic acid peel, but irritation may be reduced. Salicylic acid is a compound closely related to aspirin (acetylsalicylic acid), and it retains its aspirin-like anti-inflammatory properties. A deep BHA peel can be superior for many skin types because the irritation and inflammation are kept to a minimum due to the analgesic action of the BHA compound. Salicylic acid is also lipid soluble; therefore, it is a good peeling agent for blemish-prone skin with blackheads. The most common concentrations used today are 20% to 30%
BHA peels are also the preferred option for those with sensitive skin, including skin affected by rosacea. Note that some people with rosacea cannot tolerate salicylic acid. If you have rosacea, consider experimenting with a skin-care product that contains salicylic acid, such as one of Paula's Choice BHA exfoliants, before considering a BHA peel.

TCA Peels

Trichloroacetic acid (TCA) peels (sometimes called Blue Peel) in concentrations up to 50% are superficial to medium peels and have been around for years with a history of being effective and safe. This type of peel can be used for peeling the face, neck, hands, and other areas of the body. It has less bleaching effect than phenol (see below) and is excellent for "spot" peeling of specific areas. TCA peels are best for fine lines but are minimally effective on deeper wrinkling.
Jessner's peel is a medium-depth peel containing 14% salicylic acid, 14% lactic acid, and 14% resorcinol. Though considered effective and easy to use, there is little research on this method. We do know this peel becomes stronger as more layers are applied. The amount of resorcinol in this peel makes it more irritating than AHA or BHA peels, and it is generally not recommended for those with dark skin tones due to the risk of resorcinol causing post-inflammatory hyperpigmentation.

Phenol Peels

Phenol is sometimes, though rarely, used for full-face peeling when sun damage or wrinkling is severe. It can also be used to treat limited areas of the face, such as deep wrinkles around the mouth, but it may permanently bleach the skin, leaving a line of demarcation between the treated and untreated areas that must be covered with makeup. "Although phenol produces the most remarkable resolution of actinic damage and wrinkling among the various [chemical peels]... it also possesses some of the more significant [serious side effects]. Many have abandoned phenol in favor of other agents or laser resurfacing... . Hypopigmentation may occur in all skin types, noticeably lightening patients with darker skin and making lighter-skinned patients appear waxy or pale. A clear line of demarcation may be present between treated and untreated skin".
Buffered phenol offers yet another option for severely sun-damaged skin. One such formula uses olive oil, among other ingredients, to diminish the strength of the phenol solution. Another, slightly milder formula uses glycerin. A buffered phenol peel may be more comfortable for patients, and the skin heals faster than with a standard phenol peel, but it is still a risky procedure that can depigment the skin. On balance, we recommend forgoing phenol peels in favor of laser treatments such as Fraxel.

What About At-Home Peels?

Many women ask us about the number of peels sold online for use at home. These peels often advertise having high concentrations of AHAs or BHA and some contain other peeling agents along with these popular standbys. We cannot stress enough how potentially dangerous these peels can be. If they're as effective as claimed or if they really contain the amount of acid(s) advertised and the pH is within range for them to work, you could be setting your skin up for some serious damage. In the wrong hands or used incorrectly or too often, at-home peels can cause burns, extremely sensitive skin, discolorations (from loss of pigment), and persistently dry, flaky skin that doesn't respond to even very rich moisturizers. If you decide to ignore our warnings and try this anyway, proceed with caution.
The other issue with at-home peels is that despite the impressive claims in terms of amount of acid they contain, the pH may be buffered beyond the range needed for efficacy. So yes, the peel you're considering contains 50% glycolic acid, but because the pH when mixed is above 4, you're not going to see much in the way of results. The good news? A higher pH like this means the peel poses less risk of causing excess irritation.

The Final Decision

Whichever way, whether to have a peel and what type to get depends on the condition of your skin, your skin type, and keeping your expectations realistic. Most important is for you to know that a peel isn't an anti-aging cure-all. For example, peels cannot help with sagging skin and they don't replace the results possible from cosmetic corrective procedures such as Botox or any of the numerous dermal fillers. Peels are helpful for improving skin tone, texture, and for some cases of hyperpigmentation (brown spots) but for best results, they must be accompanied by daily use of a well-formulated sunscreen rated SPF 25 or greater along with a brilliant anti-aging skin-care routine. Now that's a beautiful combination proven to help you look younger, longer!
