PRODUCT DETAILS

If you want a serum that looks after tone without leaving hydration out of the conversation, this is a thoughtful place to start. It brings 5% beta arbutin and 5% niacinamide together in a clear, watery texture that absorbs quickly. Made for all skin types, the focused formula has a wide welcome.

Beta arbutin offers tone-focused care for visible dark spots and uneven-looking tone. Niacinamide also supports a more even-looking complexion while it helps control sebum and supports the skin barrier. Together, they bring tone care, sebum control and skin-barrier support into the same formula.

Sodium hyaluronate adds deep hydration. Alongside the two 5% ingredients, it gives you another reason to reach for this serum when hydration matters as much as a brighter-looking finish.

The finished formula helps skin look smoother and more radiant. If your goals include visible dark spots, dullness, excess shine or dehydration, this serum brings those priorities together in one formula.
