What Is Ascorbic Acid?
Ascorbic acid is the pure, unmodified form of Vitamin C, and the version with the strongest body of research behind it. As an antioxidant, it helps neutralise the free radical damage caused by UV exposure and pollution, while also supporting the skin's own collagen production.
Pure Vitamin C is naturally unstable when exposed to light and air, so ASI formulates it with Ferulic Acid and Vitamin E, a combination shown to help keep the Vitamin C stable and effective for longer.
