what it does
A large-molecule alpha-hydroxy acid derived from bitter almonds with gentle exfoliating and antimicrobial properties. Larger molecular size means slower skin penetration and significantly reduced irritation risk.
AHA for sensitive skin types who cried at glycolic acid. Bigger molecule = slower penetration = less sting. Bonus antimicrobial activity makes it decent for adult acne. Great if other acids are just too aggro for your face.
