Our concentrated Vitamin C serum beautifully brightens the appearance of your skin. Dermatologist recommended and clinically proven, this serum is formulated with a stabilized form of Vitamin C, Stay C-50®. This allows the product to work more effectively than non-stabilized forms of vitamin C which can easily degrade and lose potency, diminishing their benefits even before applying. Combining Stay C-50® vitamin C with powerful antioxidants and nature's moisture magnet, Hyaluronic Acid, our affordable vitamin c serum leaves skin looking brighter, more even, and smooth.
