PRODUCT DETAILS

Hello, brighter-looking skin. This daily facial serum brings targeted tone care and hydration into one lightweight step, helping dull-looking skin appear brighter while softening the look of dark spots over time.

The renewed formula combines two forms of vitamin C with 5% niacinamide and 2% tranexamic acid. Their roles center on brighter-looking clarity and a more even-looking tone, while alpha-arbutin is included in the serum's brightening combination. The published 63% figure refers to Hippophae Rhamnoides Water—not pure vitamin C—and this botanical water is associated with reviving the look of dullness.

On skin, the serum feels lightweight, fast-absorbing and non-greasy. It leaves a hydrated, comfortable finish without greasiness, so focused tone care doesn't have to feel heavy.

The formula also contains 5% Centella Asiatica Leaf Water for soothing care for delicate-looking skin, plus 2% betaine for hydration and a supple feel. With no artificial fragrance or coloring, it is also positioned as suitable for sensitive skin.
