The Ordinary PHA 5% Exfoliating Lip Serum is a gentle yet effective leave-on treatment designed to smooth, soften and deeply hydrate dry, textured lips. Formulated with 5% gluconolactone (PHA) and 1.5% alpha hydroxy acids, the serum delicately exfoliates dull, flaky skin while respecting the sensitivity of the lip barrier.

With over 50% glycerin and barrier-supporting ectoin, the formula delivers intense hydration, improves moisture retention and enhances the natural shine of lips. Lightweight and non-sticky, it can be worn alone or layered under a lip balm overnight to reveal plumper, smoother and more radiant lips by morning.
