Detailed answer

Glycolic acid is an alpha hydroxy acid (AHA) that effectively exfoliates the skin by removing dead skin cells and stimulating cell turnover. This process helps to reduce the appearance of fine lines, wrinkles, and uneven skin tone. Glycolic acid also aids in increasing collagen production, which helps to improve skin elasticity and firmness. Additionally, it enhances the absorption of other skincare ingredients, making them more effective. However, it is important to note that glycolic acid can increase skin sensitivity to the sun, so it is crucial to use sunscreen during the day when incorporating products containing glycolic acid into your skincare routine.
