Brighten skin and target the visible signs of ageing with the Vitamin C Suspension Serum 30% in Silicone from The Ordinary. The waterless antioxidant-packed topical formula remains completely stable due to the absence of water. Enriched with 30% of Vitamin C in its purest form (L-Ascorbic Acid), the serum helps to reduce the appearance of fine lines, wrinkles and discolouration, working best at night when skin is most receptive. The addition of very light silicones allows the serum to effortlessly glide across the skin for a silky-smooth finish. Free from water, alcohol, oil, nut, gluten and soy. Vegan. Cruelty-free. Please Note: The format of this formula is a suspension of very fine L-Ascorbic Acid powder and, as such, provides the most direct exposure of extremely high concentrations of Vitamin C topically. With such format, a very strong tingling but non-irritating sensation is expected during the first 1-2 weeks of use until the skin's tolerance to such high exposure is elevated. If the sensation is too strong to tolerate, the formula can be mixed on each application with other creams or serums of your preference.
