Vitamin C, 100% L-Ascorbic Acid, USP, fine powder is a water soluble antioxidant. Vitamin C, a potent, naturally occurring antioxidant is an important constituent of skin.  It plays a pivotal role in the prevention of dry skin and wrinkles, collagen synthesis and skin regeneration.  Ascorbate is found in all layers of the skin, but is more concentrated in the epidermis than the dermis.  However, it is readily depleted by about two thirds in cutaneous tissue stores with exposure to UV light.

Vitamin C has been shown to be effective in increasing collagen deposits and also enhancing collagen lattice contractions, implying that exogenous Vitamin C application contributes to strengthening the collagen framework and maintaining a healthy dermis.  Topical application of Vitamin C has been shown to reduce the appearance of fine lines and wrinkles. Caused by mechanisms supporting collagen production, this leads to improving the appearance of the skin.  It has further been proven to reduce the severity of sunburns and age spots.

The difficulty for most cosmetic formulators is that L-Ascorbic Acid is very unstable in aqueous solutions, as it starts to oxidize immediately, gradually producing color changes (orange/brown shift) and a reduction in activity as it converts to dehydroascorbic acid. For cosmetic use, it is best stabilized in an anhydrous lipid or silicone base, although some have reported increased stability with the use of Ferulic acid as part of aqueous formulations.

Tidesmark L-Ascorbic Acid meets USP specifications, but it is considered a cosmetic grade material once we repackage it.
