Lactic Acid

A Gentle Exfoliating & Hydrating Active for Smoother, Brighter Skin

Lactic Acid is an Alpha Hydroxy Acid (AHA) naturally derived through the fermentation of sugars. It gently exfoliates the skin by removing dead skin cells, revealing a brighter, smoother, and more even-looking complexion. Unlike stronger exfoliating acids, Lactic Acid also has excellent hydrating properties, making it suitable for most skin types, including dry and sensitive skin when used at appropriate concentrations.

It is widely used in facial serums, creams, toners, body lotions, and products designed to improve skin texture, brighten discoloration, and support healthy skin renewal.
