Wouldn't you love to use a product that helps protect the skin from the sun, neutralizes free radicals, and increases collagen synthesis? Once it is in the skin, studies show that L-ascorbic Acid (a form of Vitamin C) stimulates collagen synthesis, provides sun protection, stays in the skin for up to 72 hours, and protects skin by neutralizing free radicals, which would otherwise destroy skin and its components.

Vitamin C in a product's ingredient list doesn't necessarily mean it is effective. Vitamin C products may be at least somewhat oxidized by the time you use them. When Vitamin C oxidizes, it eventually acquires a yellowish tint indicating an advanced stage of oxidation. Unfortunately, the lack of a tint does not guarantee that the products hasn't oxidized because the the initial product of Vitamin C oxidation (Dehydroascorbic Acid) is colorless. Only a furthering of the oxidation process produces a noticeable yellowish tint. The ultimate consideration when choosing a Vitamin C product is finding a trustworthy brand, such as SkinCeuticals, and being careful to check the expiration date and packaging.
