PRODUCT DETAILS

Hello, hydration. Master Serum is a lightweight face serum for skin that feels dry, sensitive or flaky. It delivers deep hydration with soothing moisture-barrier support, bringing focused moisture and soothing care to your routine.

Centella Asiatica helps soothe sensitive skin, while Bifida Ferment Extract supports the moisture barrier. Two forms of hyaluronic acid provide multi-layer hydration and a plump, smooth feel, and panthenol helps hold in moisture and calm the feel of irritation. Each ingredient has a clear part to play in the serum's care-focused formula.

The lightweight, fast-absorbing texture settles in quickly, leaving the complexion soft, smooth and nourished. It can suit all skin types, with a particularly natural fit for dry, sensitive or flaky skin—a softly focused choice when hydration is the priority.
