Frequently Asked Questions About Glycolic Acid
Q: What exactly does glycolic acid do for the skin?
A: Glycolic acid works primarily as an exfoliant by breaking down the bonds between dead skin cells. This promotes cell turnover, revealing fresher, younger-looking skin beneath. Additionally, it stimulates collagen production, improves skin texture, reduces fine lines and wrinkles, fades hyperpigmentation, and enhances the penetration of other skincare products.
Q: How often should I use glycolic acid products?
A: The frequency depends on the concentration and your skin's tolerance. For beginners, start with a 5-10% solution once weekly. With regular use, you can gradually increase to 2-3 times weekly for concentrations under 10%, or maintain 1-2 times weekly for 10-20% solutions. Higher concentrations (25%+) should only be used as occasional treatments under professional guidance.
Q: Can glycolic acid cause irritation or side effects?
A: While generally safe, glycolic acid can cause temporary side effects including redness, stinging, or peeling - especially when first starting use or when concentrations are too high for your skin type. These effects typically subside as your skin adjusts. Always perform a patch test before full application, use sunscreen daily (as glycolic acid increases sun sensitivity), and follow with moisturizer to maintain skin barrier function.
Clinical Benefits of Glycolic Acid
Numerous dermatological studies have confirmed glycolic acid's efficacy for:
