C.E.O. 15% Vitamin C Brightening Serum

This serum takes its name from the ingredients it's formulated with—vitamin C, vitamin E, and a blend of antioxidants—but also truly lives up to its C.E.O. title, working like a boss to brighten, tighten, and plump your complexion. With a potent 15% dose of an oil-soluble version of the brightening savior called tetrahexyldecyl ascorbate (a derivative of vitamin C), it addresses signs of aging and gives you a more even-toned complexion. In this format, it can penetrate deep and fast into your skin, so you get instant radiance. And it doesn't just make your skin look more refined and clearer thanks to saccharide isomerate extract and glycolic acid, it also reduces any redness or irritation with the help of phytosterols, so even sensitive types can use it.
