The Ordinary Lactic Acid 10% Serum

The Ordinary Lactic Acid 10% + HA Serum is a high‑strength exfoliating skincare treatment formulated with 10% lactic acid, an alpha hydroxy acid (AHA) that dissolves the build‑up of dead skin cells on the surface to improve texture, smoothness, and radiance. The addition of hyaluronic acid (HA) helps draw moisture into the skin, counteracting dryness and promoting a hydrated, plumped feel.

This lightweight, water‑based serum also includes Tasmanian pepperberry extract, which may help soothe and reduce sensitivity commonly associated with exfoliation. Regular use can help even out skin tone, reduce the look of dullness and fine lines, and support clearer‑looking, more radiant skin. It’s typically applied at night on clean, dry skin, starting 2–3 times per week and increasing frequency as tolerated, and should always be paired with broad‑spectrum sunscreen during the day to protect newly revealed skin.
