PHA 5% Exfoliating Lip Serum

Share information about your product.

The Ordinary PHA 5% Exfoliating Lip Serum treats chronically flaky lips with chemistry instead of friction. Polyhydroxy acids are the gentlest exfoliating class and unusually water-binding, so it dissolves dead skin while holding hydration — which is exactly the opposite of what a sugar scrub does.

🎯 What It Does

• Exfoliates without scrubbing — dissolves dead skin chemically rather than abrading delicate lip tissue
• Hydrates as it works — PHA molecules bind water, so lips do not end up drier
• Smooths flaky patches — improves the rough texture that makes lipstick cling badly
• Stays gentle enough for daily use — no risk of over-exfoliation with regular application
• Preps for colour — a smooth base makes lipstick sit evenly
• Absorbs cleanly — no stickiness, layers under balm or lipstick

🔬 Key Ingredients

• Polyhydroxy Acid 5% — the gentlest exfoliating acid class; larger molecules mean slower, milder action
• Humectants — attract and hold moisture in the lip surface
• Emollients — soften and smooth for a supple finish

📋 How to Use

1. Apply a small amount to clean lips.
2. Use once daily, preferably in the evening.
3. Follow with a hydrating balm if needed.
4. For best results, apply overnight under a lip mask or balm.
