Description

Malic Acid is a naturally occurring alpha hydroxy acid (AHA) found in fruits such as apples. In cosmetic formulations, it is used to support gentle exfoliation, smoother skin texture, and a brighter, more even-looking complexion.

Compared to stronger AHAs like glycolic acid, malic acid provides a milder, more skin-friendly exfoliating effect, making it suitable for products designed for frequent use or sensitive skin. It also functions as a pH adjuster, helping maintain formula stability and performance.

Malic Acid is widely used in toners, serums, cleansers, masks, exfoliating treatments, and brightening formulations.
