Overusing any chemical or mechanical exfoliating agent can result in redness or irritation. However, in moderate concentrations, glycolic acid can be tolerated for daily use to help facilitate the skin’s natural exfoliation. When considering a glycolic acid treatment for your skincare regimen, it is important to identify the right concentration for your specific skin concern.
Concentrations of glycolic acid for skin under 4% provide low-level exfoliation and may be used once or twice daily depending on the potency and pH value of the formula. Sometimes glycolic acid may be added to acne formulas at lower levels to enhance skin cell turnover. If looking for an effective nighttime product that primarily targets visible signs of aging such as fine lines, dullness, and skin texture, a 4-10% concentration of glycolic acid is recommended. Any glycolic acid formulation featuring a concentration above 20% should be recommended and administered by a skincare professional. This includes chemical peels, which may require pre-conditioning and specific post-procedure care.
Due to the exfoliating nature of glycolic acid, always apply a broad spectrum sunscreen during the day when using these products.
