Vitamin C is an effective antioxidant that brightens the skin tone and reduces the appearance of signs of aging. This water-free formula provides 30% pure L-Ascorbic Acid which remains completely stable due to the absence of water. Due to the presence of very light silicones, this formulation feels smooth on the skin despite the suspension format of the formulation, avoiding the short-lived gritty feeling of our original Vitamin C Suspension 23% + HA Spheres 2% formula. This treatment is ideally applied at bedtime.
