Alpha hydroxy acids primarily serve what purpose in skincare?

Alpha hydroxy acids (AHAs) primarily serve the purpose of exfoliation in skincare. These natural acids, derived from fruits and milk, work by loosening and dissolving the bonds between dead skin cells on the surface of the skin. This allows for the shedding of these cells, revealing fresher, smoother skin underneath. The exfoliating effect of AHAs helps to improve skin texture, minimize the appearance of fine lines and wrinkles, and promote a more radiant complexion.

By accelerating cell turnover and encouraging the production of new cells, AHAs also help improve the overall tone and clarity of the skin. While AHAs can contribute to hydration as they may attract moisture to the skin, their primary and most significant role in skincare is indeed exfoliation. This makes them particularly beneficial for dull or uneven skin types.
