Malic Acid

Malic Acid is an alpha-hydroxy acid (AHA) naturally found in apples and other fruits, though cosmetic-grade material is typically produced through fermentation. It offers a gentler exfoliating action compared to glycolic acid due to its larger molecular size, while providing superior pH buffering capacity that helps maintain formulation stability over time. Formulators favor malic acid for its dual functionality as both a pH adjuster and mild exfoliant, plus its ability to enhance skin hydration by supporting the natural moisturizing factor in the stratum corneum.
