The Ordinary PHA 5% Exfoliating Lip Serum

PHA 5% Exfoliating Lip Serum by The Ordinary.

The Ordinary PHA 5% Exfoliating Lip Serum is designed to gently transform dry, uneven lips into a smoother, softer surface. Unlike harsh scrubs, this formula uses a chemical-based exfoliation system with 5% Gluconolactone, a polyhydroxy acid (PHA) that works to dissolve the bonds holding dead skin cells together. Thanks to their larger molecular weight, PHAs remain on the surface of the skin, offering mild yet effective exfoliation that’s suitable even for sensitive lips. To enhance the smoothing action, 1.5% alpha hydroxy acids, including citric, tartaric, and malic acids, help refine texture and promote a naturally fresh look.

PHA 5% Exfoliating Lip Serum doesn’t stop at exfoliation, it also replenishes and protects. With a high concentration of glycerin (over 50%), it draws in water and locks in hydration, helping lips stay plump and supple. Ectoin, a powerful stress-protection molecule, supports the skin barrier while offering long-term hydration benefits. Black carrot extract adds antioxidant protection and lends a subtle pink hue to the formula, a naturally derived tint that may vary from batch to batch.

The result is lips that feel smoother, look healthier, and maintain moisture more effectively over time. Gentle enough for three-times weekly use, this vegan-friendly formula is oil-free, silicone-free, and thoughtfully created for anyone seeking a no-fuss, effective solution to improve lip texture.

With The Ordinary PHA 5% Exfoliating Lip Serum, your lips get both the care and the science they deserve—hydrated, soft, and perfectly prepped for whatever comes next.
