Vitamin C is a strong antioxidant and reducing agent. On topical application and under suitable conditions, it can penetrate into the deeper layers of the epidermis where the melanocyte cells are located. These cells produce the protective brown pigment, melanin, on exposure to actinic (U.V.) light. L-Ascorbic acid, if present in sufficient concentration, reduces melanin to a colorless substance, inhibiting the formation of freckles, excessive darkening of the skin, “age spots” and possible, precancerous lesions such as melanomas while at the same time brightens the skin.
L-Ascorbic acid is one of the protective substances which are involved in the capturing or neutralizing of free radicals formed upon exposure to U.V. radiation before they damage skin cells and accelerate aging.
Vitamin C is widely used in dietary supplements. Its use in dermatological and cosmetics has been inhibited due to its lack of stability in the vehicles employed in these products. This important use can now be implemented on the basis of the availability of L-Ascorbic Acid Polypeptide, the stable form of ascorbic acid that is essential for cross linking collagen molecules.
Vitamin C + has a pronounced toning and firming effect on the skin, making it suitable as an ingredient in cosmetics intended for use in the vicinity of the eyes (reduction of puffiness,etc.) as well as skin care products for aging and mature skin as it builds collagen.
Due to its melanin reducing properties, Vitamin C + can improve the appearance of freckled complexions, age spots and discolored skin areas.
The protein and carbohydrate constituents of Vitamin C serve as excellent moisturizing and counter-irritating agents which penetrate deeply into the epidermis thereby decreasing the trans-epidermal water loss.
