Glycolic acid isn't the best option for ultra-sensitive, reactive, or compromised skin, as it can aggravate these conditions and lead to more intense discomfort. Therefore, the best option might be a gentler exfoliating agent, like lactic acid, which can help improve most skin concerns glycolic acid tackles without causing irritation. However, if you still want to try glycolic acid, opt for a product with a mild concentration and use it sparingly.
