Glycolic Acid
What is Glycolic Acid?
Glycolic acid is the smallest alpha hydroxy acid (AHA), a naturally occurring organic compound derived from sugarcane and other fruits. Chemically known as hydroxyacetic acid, it features a simple two-carbon structure that allows deep skin penetration. In cosmetics, it belongs to the exfoliating acid category and serves as a key active in cleansers, toners, serums, and peels. It functions by disrupting the bonds between corneocytes in the stratum corneum, facilitating gentle removal of dead surface cells. Additionally, it acts as a pH adjuster and buffering agent to stabilize formulations. This chemical exfoliation promotes cell turnover, enhances product absorption, and supports overall formulation efficacy without abrasive particles.
