PRODUCT DETAILS

Hello, hydration. This leave-on serum is for days when your skin looks tired or feels less bouncy. It brings together moisture that helps your skin stay hydrated, fresh-looking radiance and a plumper feel in one easy addition to your routine.

Three forms of hyaluronic acid help make that hydration story clear. Hyaluronic Acid, Hydrolyzed Hyaluronic Acid and Sodium Hyaluronate act as humectants, helping attract and hold water for comfortably hydrated skin.

The after-feel is light yet hydrating, while skin feels plumper, smoother and more refined after use. It is a balanced finish for anyone who wants moisture without giving up a lighter feel.

The serum is also recommended for sensitive or easily reactive skin and has completed a low-irritation test. It keeps the focus gently on hydration, radiance and bounce.
