What is the primary function of glycolic acid in skin care?

The primary function of glycolic acid in skin care is exfoliation. Glycolic acid, an alpha hydroxy acid (AHA), is known for its ability to penetrate the skin and help in the shedding of dead skin cells from the outer layer. This exfoliating property promotes cellular turnover, allowing newer, healthier skin to emerge. As a result, it can improve skin texture, unclog pores, and enhance the overall appearance of the skin.

This exfoliation can also help to reduce the visibility of fine lines, wrinkles, and hyperpigmentation, making it a popular ingredient in various skin care products, particularly for those targeting aging skin or conditions such as acne. When incorporating glycolic acid into a skincare regimen, it is essential to consider the appropriate concentration and to be mindful of sun protection, as exfoliated skin can be more sensitive to UV radiation.
