| How to Safely Use Alpha Hydroxy Acids in Cosmetics By: Cherish Hamutoff The most common types of alpha hydroxy acids (AHAs) found in skin cosmetics are glycolic acid (derived from sugar) and lactic acid (derived from milk). These acids work as an exfoliant, which sloughs off the top layer of dead skin, so the fresh and smoother skin underneath can be revealed. AHAs are used to smooth wrinkles and fine lines, even out pigmentation, and improve sun damage and signs of aging. Alpha hydroxy acids can be added to various skin care products such as moisturizers, eye creams, cleansers, toners, foundations and masks. Because AHAs are exfoliating, they can cause some adverse reactions, including redness, burning, swelling, discoloration, rash, blistering, peeling, itching, tenderness and increased sun sensitivity. Sun sensitivity can last for several weeks after use. Precautions can be taken to avoid these unpleasant side effects. To safely use AHAs in cosmetics, make sure to: • Always protect skin from the sun with a broad-based SPF of 15 or more. Cover up with a wide-brimmed hat and sunglasses. • Check the label to see which AHAs are used in the product. • Use a product where the AHA concentration is no more than 10 percent. • Choose a product where the pH is 3.5 or greater. • Choose products that are formulated to reduce sensitivity. • Perform a small skin patch test to check if the AHA product causes any sensitivity, before using it on a larger area. • Don’t overuse AHA products. Only use one product with AHAs at a time. • Immediately cease product use if a reaction such as bleeding or extreme stinging or redness occurs. • Check with your dermatologist or doctor if you experience problems. Alpha Hydroxy acids are a common ingredient in many cosmetics and can be safely used to improve the tone and texture of skin if used properly. |
