Lactic Acid in skincare: is it safe?
Alpha-hydroxy acid (AHA) exfoliant
What it is
Lactic Acid is an alpha-hydroxy acid (AHA) exfoliant.
Is it safe?
Lactic Acid is permitted in cosmetics but restricted by concentration under EU rules — Klyva flags it at low concern. An AHA exfoliant at higher strengths; gentle at low levels — and we can’t see the concentration.
