5 Things To Know About Vitamin C
Necessary for Growth, Development and Repair of Body Tissue
Vitamin C isinvolved in many body functions including - formation of collagen (which is what gives skin it's structure, collagen degradation causes lines and wrinkles), absorption of iron, (lack of iron can cause extreme fatigue, weakness, pale skin, headaches, pale skin, cold extremities, and brittle nails)proper functioning of the immune system (helps protects body from toxins, bacteria, viruses and fungi),wound healing and the maintenance of cartilage and bones (Vitamin C intake has shown to lower risk of bone fractures).
Vitamin C can be used for Skin Brightening
Vitamin C is a tyrosinase antagonist. Tyrosinase is the rate-limiting enzyme in melanogenesis, catalyzing tyrosine through DOPA and DOPAquinone. This ultimately creates the pigment melanin. By using ingredients such as vitamin C that inhibit the melanogenesis process, one can significantly improve the look of pigmentation.
Vitamin C is a Natural Sun Protectant
Most significant environmental damage to the skin comes on a daily basis from our exposure to the sun. The primary reason damage is caused by UV radiation exposure is from the creation of reactive oxygen species that, in turn, damage extracellular matrix components and affect both the structure and function of cells. Vitamins E, C and antioxidant enzymes help to quench these oxidants and repair the resultant damage.
Vitamin C is an Antioxidant
Vitamin C has the ability to neutralize many free radicals (molecules that damage skin cells), especially when compared to another antioxidant powerhouse, vitamin E. But it also has the added benefit of recycling and regenerating oxidized vitamin E, thereby effectively boosting the benefits of vitamin E.
The Formula is VERY Important
Not all vitamin C is created equal. Different formulas have better or worse absorption into the skin, or shorter or longer shelf-lives. Vitamin C stability is significantly improved when a manufacturer opts for an encapsulated, fat-soluble vitamin C such as ascorbyl tetraisopalmitate. It allows 10 times more Vitamin C into the skin cell itself, and is a more stable formula whose effects that can last more than a year. The alternative, L-ascorbic acid, has a limited shelf life, is not readily absorbed and may cause irritation to sensitive skins or those prone to breaking out.
