The Ordinary Lactic Acid 5% + HA Serum is a targeted skin‑refining treatment designed to deliver gentle chemical exfoliation while supporting moisture retention. Featuring 5% lactic acid — an alpha hydroxy acid (AHA) — this water‑based formula helps to dissolve dead skin cells on the surface, promoting improved texture, a brighter complexion, and more even skin tone without excessive irritation.
To balance exfoliation with hydration, this serum includes hyaluronic acid (HA), a powerful humectant that draws moisture into the skin to help maintain softness and prevent dryness often associated with acid use. Some formulations also contain Tasmanian pepperberry extract, known to help soothe sensitivity that can occur with acid exfoliation.
This lightweight, fast‑absorbing serum is ideal for those new to chemical exfoliants or anyone seeking a gentler alternative to stronger AHAs like glycolic acid. Use it once daily in the evening after cleansing, and always follow with broad‑spectrum sunscreen during the day, as exfoliating acids can increase sun sensitivity.
