The Ordinary's Lactic Acid 10% HA is a gentle exfoliating serum that combines lactic acid and hyaluronic acid to renew skin by removing dead cells and improving texture and tone. Ideal for those looking to start using chemical exfoliants without irritating their skin, thanks to its low concentration and Tasmanian peppercorn extract, which reduces sensitivity. Its benefits include correcting uneven skin tone, softening fine lines, and smoothing texture. It's recommended to use only if your skin is not very sensitive and to patch it before applying.
