The Ordinary Lactic Acid 5% + Ha
The Ordinary Lactic Acid 5% + HA is a mild chemical exfoliant designed to gently resurface the skin and improve overall radiance. As a member of the Alpha Hydroxy Acid (AHA) family, Lactic Acid works by breaking down the bonds between dead skin cells on the surface, revealing a smoother and more even-toned complexion underneath. This 5% concentration is specifically formulated for those with sensitive skin or individuals who are new to direct acids. The inclusion of purified Tasmanian Pepperberry helps to reduce the potential for inflammation and sensitivity that can sometimes accompany acid use. To ensure the skin remains hydrated during exfoliation, The Ordinary has enriched this serum with Hyaluronic Acid (HA) and Glycerin. These humectants draw moisture into the skin, preventing the dryness or tightness often associated with peeling products. The texture is a very lightweight, water-based serum that glides easily over the skin and absorbs quickly without leaving a tacky or oily residue. It is a minimalist yet effective solution for dullness and uneven texture.
Our Analysis
Our deep dive into the ingredients of The Ordinary Lactic Acid 5% + HA confirms a LOW comedogenic risk level. We found no flagged ingredients that are known to clog pores or trigger acne. The formula is primarily composed of water, Lactic Acid, and skin-replenishing humectants like Glycerin and Propanediol. Because Lactic Acid is an exfoliant, it actually helps keep pores clear by preventing the buildup of dead skin cells. This oil-free, non-comedogenic profile makes it a safe and effective choice for users who are prone to breakouts but still want to improve their skin texture.
Skin Type Recommendations
This product is best suited for dry, sensitive, and acne-prone skin types looking for a gentle introductory exfoliant. Its mild concentration is excellent for those with a compromised barrier. While safe for oily and combination skin, those with very resilient skin may eventually prefer a stronger 10% concentration for more dramatic results.
