Guinot’s Anti-Dark Spot Serum is a new two-week treatment that works to reduce and brighten dark spots caused by sun exposure and aging. This serum rejuvenates the skin and restores a youthful appearance using Vitamin C along with a range of 56 active ingredients to help stimulate cell renewal and boost collagen synthesis. Melanoxyl and Phytic Acid are used to help reduce melanin production, which minimizes and prevents the appearance of dark spots. When combined with pure Vitamin C, the serum eliminates dead and pigmented cells to help improve cell renewal for smoother, more radiant skin after just two weeks.
