Vitamin C is one of the main non-enzymatic, water-soluble antioxidant and is required for the synthesis of collagen, an important structural component of blood vessels, tendons, ligaments and bones. In addition, vitamin C is required for the synthesis of carnitine, a small molecule that is essential for the transport of fat to cellular organelles called mitochondria, for conversion to energy. It plays a critical role in dermal construction, stimulating collagen synthesis of dermal fibro-blasts. This is thought to occur as a result of ascorbate directly stimulating collagen synthesis, directly and specifically activating collagen gene regulation both by increasing the transcription rate and stabilizing pro-collagen messenger RNA, thus genetically signaling collagen synthesis. Another mechanism is the initiation of lipid per-oxidation, which leads to an increase in a by-product, which stimulates collagen gene expression.
In addition, Vitamin C is necessary to form lysyl hydroxylase, an enzyme necessary for cross-linking one collagen molecule to another, providing tissue strength. Use of Vitamin C prevents and treats photo-ageing. UV light exposure depletes up to two thirds of cutaneous Vitamin C stores.
