What It Is: Now made to glow beyond for clinically proven results on not only the face, but the back of hands, neck, and décolleté as well.  This breakthrough in skincare science combines brightening Vitamin C and correcting Retinol – a first in its category, busting the myth that Retinol and Vitamin C couldn't safely be used together.   The non-tacky, fast-absorbing formula features stabilized antioxidants, gentle Retinol, and our exclusive barrier-strengthening form of Niacin. Use to even skin tone and skin texture, target dark spots on skin, and smooth fine lines and wrinkles.  The best antioxidant serum is one you can use anywhere you need it, including overexposed and delicate areas like on a sun-spotted décolleté, aging hands, or chest wrinkles.
