Alpha Hydroxy Acids are a class of chemical compounds that act as exfoliants on the skin's surface. By dissolving the bonds between dead skin cells, they promote cellular turnover, which can stimulate collagen production, improve skin texture, and reduce the appearance of photoaging. From a healthspan perspective, maintaining the integrity and function of the skin barrier is a key aspect of overall health, protecting against environmental insults.
