Description
The Ordinary PHA 5% Exfoliating Lip Serum is a gentle, water-based treatment developed to exfoliate, smooth and hydrate the lips without using abrasive particles.
The formula combines 5% gluconolactone, a polyhydroxy acid, with 1.5% alpha hydroxy acids. These ingredients provide surface-level exfoliation that helps remove dry, dead skin and supports a smoother-looking lip texture.
More than 50% glycerin helps attract and retain moisture, while ectoin supports the lips’ moisture barrier and provides lasting hydration. Black carrot juice gives the serum its naturally pink-to-peach colour and may cause slight colour variations between products without affecting performance.
Suitable for
Suitable for all skin types, including sensitive lips, and particularly useful for:
- Dry or dehydrated lips
- Flaky or rough-feeling lips
- Uneven-looking lip texture
- Lips requiring gentle surface exfoliation
- Those seeking smoother and more hydrated-looking lips
The product is designed to address dryness, dehydration, textural irregularities and moisture-barrier support.
How to Use
Apply a thin layer to clean, dry lips on alternate evenings as required.
Allow the serum to dry before applying another lip product. A lip balm may be applied afterwards or used throughout the day when needed.
Apply only to unbroken skin and avoid contact with the eyes. Complete a patch test before first use. If irritation occurs, rinse the product off and discontinue use.
Use sunscreen or an SPF lip balm before sun exposure. Keep out of the reach of children.
