Powered by 23% pure Vitamin C, the serum provides powerful antioxidant care while helping fade the appearance of dark spots, post-blemish marks and hyperpigmentation. It also helps improve the appearance of fine lines and wrinkles, while Sodium Hyaluronate replenishes moisture and helps prevent dehydration for a plumper, more comfortable complexion.

The concentrated formula is ideal for those looking to introduce a high-strength Vitamin C treatment into their skincare routine. With regular use, Advanced The Vitamin C 23 Serum helps leave the skin looking brighter, more even and revitalized while supporting a smooth, healthy-looking glow. For daytime routines, always follow with sunscreen to help protect the skin from UV exposure.
