Vitamin C has been well tested for it's inhibitory activity in melanin production.
Many studies also show Vitamin C is required for collagen synthesis, which declines markedly in aging skin. As we grow older, collagen synthesis is deteriorated when Vitamin C supplies is affected by the diminishing of micro capillary circulation within the skin. Topical application of Vitamin C has proven to increase collagen production.
Vitamin C, as an antioxidant, reduces the sun damage on the skin by neutralizing free radicals.
Vitamin C also stimulates collagen and elastin production in the skin. Vitamin C regenerates Vitamin E in the skin and enables Vitamin E to provide sustained antioxidant protection in the skin's elastic fibers. When your skin is injured, Vitamin C is needed in scavenging free radicals and in synthesizing collagen to speed healing.
In summary, benefits to expect when using topical Vitamin C preparations:
1. Improve skin appearance by reducing fine lines and wrinkles.
2. Wound healing as it aids in stabilising collagen
3. Protects against or lessen the severity of sunburn.
