The formula also includes ectoin for barrier support and black carrot extract for antioxidant benefits and a natural pink tint. Expect a faint tangy taste from the food-grade exfoliating acids; this does not affect performance.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this serum gently exfoliate lips without irritation?\u003c\/h3\u003e\n\n\u003cp\u003eThe Ordinary uses 5% gluconolactone (a PHA) combined with 1.5% AHAs to loosen surface dead skin rather than mechanically scrubbing it away. PHAs have a larger molecular size, which limits penetration and reduces irritation, making them suited for delicate lip skin. Ectoin and glycerin accompany the acids to maintain moisture and support the barrier during renewal.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e5% gluconolactone provides mild, surface-level exfoliation.\u003c\/li\u003e\n  \u003cli\u003e1.5% AHAs assist in smoothing texture without aggressive penetration.\u003c\/li\u003e\n  \u003cli\u003eHigh glycerin content (\u0026gt;50%) boosts hydration and prevents dryness.\u003c\/li\u003e\n  \u003cli\u003eEctoin helps protect and stabilize the lip barrier through exfoliation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen and how should I use it for best results?\u003c\/h3\u003e\n\n\u003cp\u003eApply a thin layer to clean, dry lips on alternate evenings or as tolerated; allow it to dry before covering with balm if desired.
