Vitamin CC vitamin is a water-soluble vitamin that is needed for the normal growth and repair of tissues in all parts of the body. From skin anti aging perspective, its importance is also due to the fact that it is necessary to form collagen, an important protein used to make skin, scar tissue, tendons, ligaments, and blood vessels. The vitamin is essential for the healing of wounds, and for the repair and maintenance of cartilage, bones, and teeth. As an antioxidant, C vitamin block some of the damage caused by free radicals, which are by-products that result when our bodies transform food into energy. Antioxidants also help to reduce the damage to the body caused by toxic chemicals and pollutants. As part of anti aging regimen, it is important to note that as a water soluble component, C vitamin is not stored in the body, so it must be replaced as it gets used. Also, Vitamin C increases the amount of iron absorbed from foods. C vitamin is very popular in skin anti aging creams, as it has been found effective in clinical studies for anti aging purposes.
