This glycolic acid serum contains a 10% AHA concentration to gently exfoliate the skin, promoting cell turnover and improving skin texture. It helps to minimize the appearance of fine lines, wrinkles, and dark spots, resulting in a brighter and more youthful complexion. However, due to its exfoliating properties, it may cause sensitivity and irritation, especially for those with sensitive or reactive skin. It is important to follow with sunscreen during the day when using this serum.
