Dull, uneven skin starts looking fresher. With 13% pure vitamin C in a watery serum, it fades dark spots, blemishes and freckles with regular use and leaves skin brighter and more radiant. Vitamin E adds antioxidant care, and hyaluronic acid keeps it comfortable and non-sticky. Light enough for morning and evening, and its slight yellow tint is just the vitamin itself.
