AHA exfoliant that helps remove dull surface cells while also contributing humectant properties.
Lactic acid is an AHA that exfoliates the skin surface while also contributing humectant properties. It is often chosen when a formula aims to improve dullness and rough texture without relying on the smallest, most aggressive AHA molecule. Its effect depends on concentration and formula pH, and sensitive skin may still experience stinging.
Usage & cautions
Can sting or irritate sensitive skin. Introduce gradually and use sunscreen.
Information approach
