Glycolic acid is a type of alpha hydroxy acid derived from sugarcane. An all-natural, water-soluble chemical exfoliant, it is commonly found in topical cosmetic products for aging, sun damaged and acne-prone skin. Glycolic acid is generally considered safe for dark skin and is often used to diminish the signs of hyperpigmentation, a harmless condition characterized by dark, discolored patches of skin. Show
BackgroundHyperpigmentation occurs when over-stimulated or damaged cells make too much melanin, the chemical that determines skin color. A number of factors trigger this condition, including hormones, sun exposure and injury to the skin caused by burns, scratches and acne. Though hyperpigmentation can affect men and women of all races, people of color are most susceptible.
Glycolic Acid BenefitsAha Vs. BhaGlycolic acid is available in several cosmetic preparations, from over-the-counter lotions to medical-grade superficial facial peels 4. The chemical works to rejuvenate skin by penetrating the uppermost layer of the epidermis. There, it helps break apart the dead, damaged cells for easier removal and exposes the healthier layer of skin beneath. Glycolic acid can help fade the effects of hyperpigmentation by gradually peeling away dark marks and scars.
Over-the-Counter PreparationsOver-the-counter glycolic acid products are available in 5 to 20 percent concentrations. Products include face washes, lotions and serums, which are formulated for frequent self-application. People usually see results within a few months, according to Dr. Susan Taylor, author of “Brown Skin. 3”
Chemical PeelsWhat Are the Benefits of Kojic Acid?Glycolic acid peels for hyperpigmentation are given as a series of four to six treatments, each one spaced about a month apart 14. Peels range in strength from 20 to 70 percent. Due to the higher concentration of acid, chemical peels have the potential to further damage skin. Only a doctor or qualified aesthetician should perform chemical peels.
ConsiderationsGlycolic acid is tolerated well by darker pigmented skins, especially when the treatment strength is gradually increased over time, according to “Glycolic Acid Peels,” by Ronald L. Moy 4. However, glycolic acid is not for everyone. While common side effects include temporary stinging, redness and mild irritation, more severe reactions can result in scarring and even worse hyperpigmentation. As with all medicines, consult a professional before use.
Aesthetician Dija Ayodele of the Black Skin Directory sheds light on chemical peels for darker skin tones and how to ensure a successful skin peel experienceDija Ayodele | Image: FotoliaA question, I am often repeatedly asked is – ‘Can black skin have chemical peels?’ Whilst there have been a lot of myths and misconceptions over the years, the short answer is yes – darker skin tones can have chemical peels, but with caution. In this article, I will take you through the ins and outs of chemical peeling, different types of peel agents, what skin conditions chemical peels are suitable for and the precautions that you need to follow to ensure a successful skin peel experience. What is a chemical peel?Simply put, it’s the application of an acid solution that sloughs off old, scaly, dull and poor performing skin cells to improve the appearance of the skin and hasten skin regeneration. Why would you need a chemical peel?Used at its simplest a chemical peel will lift and brighten the tone of your skin. But you can have a chemical peel for any number of reasons – fading age spots, improved texture and smoothing rough skin, fading scarring, hyperpigmentation and imperfections, evening out and unifying your skin tone, tackling early fine lines and wrinkles, rejuvenating ageing skin and reducing outbreaks of spots and acne. What types of peels are there?Peels are classified in four levels, starting with superficial peels which target the top layers of skin (epidermis), medium peels affect the dermis and deep peels penetrate right through the dermis. For most skin concerns, a course of superficial peels is ideal. They have very little down time, the skin heals quickly and it is easier to control the outcome. Medium peels tend to be too aggressive for black skin, whereas deep peels are wholly unsuitable due to the risk of severe scarring. What types of peels are suitable for black skin?With so many different types of chemical agents available, it’s important to know something about how they work and what they can be used for. Most peels will have an alpha-hydroxy (AHA) or beta hydroxyl (BHA) base, though sometimes peels agents are used singularly in a pure form or in combination with each other. Lactic Acid (AHA)This is
a gentle peel derived from soured milk and good for sensitive skin types. Lactic acid is also found naturally in the skin and is a natural humectant, so not only will it remove afore mentioned dullness but it will also help your skin draw and retain moisture, leaving it smooth and plumped out. Mandelic Acid (AHA)This
has gentle surface action and is both anti bacterial and anti inflammatory. It is derived from bitter almonds, so nut allergy sufferers beware. Salicylic Acid (BHA)Great for oily and congested skin types. It is a mild anti-inflammatory peel that can deep cleanse pores to remove debris and built up oil. It also contributes
to the effective shedding of old skin cells. If you’re allergic to aspirin, then beware of salicylic acid as they are from the same chemical family. Glycolic Acid (AHA)One of the original chemical peeling solutions made from sugar cane. A highly efficient, high performance work horse for many
aestheticians. Citric Acid (AHA)Derived particularly from oranges and lemons. It creates a mild peeling effect but is often added to other peels as a gentle booster for its antioxidants, plumping and brightening effects. Precautions for black skinOne of the primary concerns for black skin when having any skin treatments, including peels is the potential to develop Post Inflammatory Hyperpigmentation. That is, instead of clearing the hyperpigmentation the treatment does the opposite and creates more hyperpigmentation, dark marks and scarring. Therefore, it is important to ensure your skin is properly prepped and primed in the weeks leading up to the peel. This could be in the form of a preparatory peel or using home-care products with similar ingredients to the peel. It is also important to leave adequate time between treatments to allow skin to heal. Ten to fourteen days is ideal, though some peel treatments can require up to four weeks. It is also important that a full medical history is disclosed including discussing your propensity to scar. If you’ve suffered from keloid scarring in the past, then peels are not advisable. Are you applying sunscreen on a daily basis? If you want to have peels, then it is a must to wear sunscreen of at least SPF 30 everyday to prevent further damage to your skin and post treatment inflammation. Skin care…Can you use glycolic acid on brown skin?One of the most popular AHAs, glycolic acid, is still suitable for dark skin according to the founder of the Black Skin Directory Dija Ayodele – but darker skin tones must ensure they don't overuse these treatments and take care to utilize them correctly. Start with a low %. Always patch test and listen to your skin.
Do chemical peels work on brown skin?The Answer is … YES!!! Exfoliating agents such as professional chemical peels, enzymes and at-home skin care treatments are a great option in treating hyperpigmentation for all skin colors, especially darker skin tones.
Is glycolic acid good for people of color?While many say that people with deeply colored skin should steer clear of glycolic acid, this claim is actually very generalizing. Because glycolic acid helps push new cells to the surface, glycolic acid can definitely help with PIH on melanin-rich skin as well.
What percentage of glycolic acid is safe for dark skin?Glycolic Acid (or a combination of AHA's) should be used at a maximum concentration of 10% or less and the final product should have a pH of 3.5 or greater. (Higher percentages of up to 30% Glycolic Acid or AHA's are safe for use in professional products by trained experts).
