Want to brighten your skin and defy the signs of aging (we're talking discoloration, fine lines, and dark circles) overnight? You need the Ordinary Vitamin C 30% Suspension in Silicon. In its pure form of ascorbic acid, Vitamin C is a potent antioxidant that has been shown to visibly brighten skin and reduce signs of aging when applied topically. This waterless formula provides skin with a very high concentration (30%) of pure L-Ascorbic Acid that remains completely stable due to the absence of water. The addition of very light silicones means this formula feels wonderfully smooth on the skin, although a strong (but non-irritating) sensation can be expected for the first 1-2 weeks of use until skin tolerance to a high concentration of vitamin C is improved (can be mixed Formula with other creams and serums to reduce this sensation if needed). Perfectly applied at night, this gorgeous formula works hard while you do the opposite, leaving you with smooth, radiant, and even skin when morning comes.
