Vitamin C, which is also known as Ascorbic Acid, a water soluble ingredient, is considered to be a ‘gold standard’.

It is an antioxidant which helps in neutralizing free radicals (a highly reactive molecule), and along with it also helps in curing and preventing pigmentation, UV stress (sun damage) and pollution.
