Glycolic acid, an Alpha Hydroxy Acid, exfoliates the outermost layer of skin cells, promoting cellular turnover. This process can reduce the appearance of fine lines, hyperpigmentation, and improve skin texture and elasticity. It also supports collagen synthesis, contributing to skin integrity and a youthful appearance, which can be considered a local aspect of healthspan.
