The Ordinary PHA 5% Exfoliating Lip Serum ingredients: is it worth it?
A legitimately useful lip exfoliant, but a basic 5% acid gel—not a miracle plumper or repair treatment.

READ MORE
The efficacy score is 3.5/5: gluconolactone is the second-listed ingredient and the brand identifies it as the 5% PHA, while the additional citric, malic, and tartaric acids support surface exfoliation. The final result depends heavily on pH, which is not disclosed, so optimal acid activity cannot be confirmed; ectoin may support comfort, but the formula contains no substantial emollient or occlusive system for lasting lip barrier repair. The formula is fragrance-free and has a short preservative system, supporting a safety score of 4.6/5, although multiple acids can sting chapped or fissured lips. The product is intended to exfoliate and hydrate lips with 5% gluconolactone.
