Main active: Hyaluronic Acid

PRODUCT DETAILS

Hello, hydration. This leave-on ampoule gives your routine hydration support from 10,000 ppm sodium hyaluronate. Sodium hyaluronate is the predominant commercial cosmetic form of hyaluronic acid, an ingredient used to support skin hydration.

The texture is a lightweight daily layer. Its slightly acidic formula has a pH range of 5.0–6.0, a useful detail when you're comparing ampoules.

The supporting formula story stays focused. It includes glycerin for hydration and skin-barrier support. Glyceryl glucoside contributes another moisture-supporting role, while allantoin provides skin-conditioning support. Together, they round out the ampoule's hydration-first profile while keeping sodium hyaluronate at the center.
