Vitamin C Defined
Vitamin C is a water soluble vitamin that is a potent anti-oxidant. Vitamin C serum - a form of vitamin that can be absorbed by skin cells - is an important ingredient. Topical Vitamin C is capable of controlling inflammatory responses associated with UV exposure, which is seen as the cause of damage that eventually leads to wrinkling and skin cancer. It also acts as an antioxidant and promotes collagen synthesis.

Many of the Vitamin C skin care products available are not all they seem. Vitamin C has been proven to have an anti-aging, wrinkle reducing and skin rejuvenating effect. Many Vitamin C products, however, cannot deliver the full dose of Vitamin C Anti-Oxidants they claim to have. The reason is simple - Vitamin C does not last.

Why Vitamin C does not last? In brief, an oxidation process occurs which destroys the nourishing effects of the Vitamin C. Once the Vitamin C has been dissolved into a skin care cream or serum the Vitamin C Anti-Oxidants are broken down to become ineffective in the treatment of your skin.

How Does Crx Vitamin C ensure freshness? Naturalskinshop.net has chosen to offer the Crx product range as they are unique in quality with a product freshness guarantee. The Vitamin C Serum you purchase was manufactured within the month of your time of your order. In fact, we visited the facility and observed their process of manufacturing small batches twice per week to provide high concentration with high anti-oxidant yields and almost no oxidization. Almost all reputable Vitamin C skin care suppliers privately acknowledge when you buy their product it has likely been on the shelf or in a warehouse for several months.

Can't Vitamin C be stabilized to last? Yes, but only in low concentrations - usually when tested by independent labs stabilized concentrations are found to be less than 12% regardless of claims made

Vitamin C is widely distributed in the plant and animal kingdom.The best sources in nature are citrus fruits. The vitamin in nature is always conjugated with water soluble proteins or polypeptides and generally occurs in conjunction with related compounds, the bioflavonoids. The conjugated (polypeptide-bound) form of vitamin C is approximately 10 times more effective than synthetic vitamin C.

Studies have shown that L-Ascorbic Acid Polypeptide on oral administration gives rise to plasma levels for approximately 24 hours while synthetic ascorbic acid is almost totally excreted after 6 to 8 hours.

Vitamin C plays an important part in many metabolic processes and must be ingested daily since it is not produced by the body. Vitamin C is necessary for the biosynthesis of hydroxyproline, a precursor of collagen, osteoid and dentin. It is required for the immune system and for wound healing and strengthens the capillary blood vessels thus preventing their fragility and subcutaneous bleeding.

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 sufficent 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.

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.
