Vitamin C plays many beneficial roles in the body. Recent studies have shown that topically applied vitamin c is much more effective on the skin than taking the vitamin orally.An effective way to obtain vitamin C topically is through a serum. While there are many serums out there, it is important to make sure that the product you are using has at least 15% of the vitamin, and also that the form of that is utilized is actually bioavailable. If you want to know more about this, check out Vitamin C Serum. Most products on the market u se L-Ascorbic Acid, which is essentially just plain old vitamin C. This form is very unstable (meaning the risk for oxidation is great), and not easily absorbed through the skin (but better utilized in oral supplements). More bioavailable forms of the vitamin that are absorbed well through the skin, include Sodium Ascorbyl Phosphate as well as Magnesium Ascorbyl Phosphate. These are both the salts of Ascorbic Acid, and are absorbed into the skin much more effectively than plain L-Ascorbic Acid.When vitamin E is added to a vitamin C serum, the photo-protecting effects of the serum is around 400%. Meaning, skin exposed to ultraviolet rays will be essentially 4 fold more resistant to damage than untreated skin. A recent study from Duke found that when ferulic acid, a naturally occurring substance found primarily in plant cell walls, was added to a serum consisting of vitamin C and E, this photo-protecting effect was raised to 800%.The topical application of vitamin C is not only effective at preventing skin damage, but also healing already done damage. The antioxidant works to eliminate discoloration, and heal scarring & wrinkles associated with both aging as well as free radical and UV damage.Utilizing products containing the effective antioxidant in your daily skin care routine is crucial to keeping your skin looking young and healthy for years to come.
