What effect do alpha hydroxy acids (AHAs) have on the skin?

Alpha hydroxy acids (AHAs) are well-known for their abilities to exfoliate the skin and promote cell turnover, which is crucial for maintaining a healthy complexion. AHAs work by breaking down the bonds between dead skin cells, allowing for easier shedding and revealing fresher, more radiant skin underneath. This process not only enhances the skin's texture but can also improve its overall appearance by minimizing the look of fine lines and wrinkles. By stimulating the production of new skin cells, AHAs help to promote a more youthful and vibrant complexion.

In contrast, although some people may observe additional hydration and improvements in their skin after using AHAs, this is not their primary function. Prevention of acne outbreaks is more typically associated with other ingredients like salicylic acid. Similarly, altering skin pigmentation falls outside the usual benefits of AHAs, which focus on surface-level exfoliation rather than deep changes in pigmentation. Therefore, the most accurate understanding of AHAs is their role in exfoliating the skin and enhancing cell turnover, making this the key benefit they provide.
