Vitamin C
Vitamin C is one of the most well-researched and beneficial vitamins you can apply topically. Ongoing use has been shown to improve the look of multiple signs of aging, brighten an uneven skin tone, as well as provide skin-restoring and soothing benefits.

The Details
A stable, oil-soluble form of Vitamin C that has the ability to increase collagen levels, reduce melanin production, brighten skin, and repair the effects of UV exposure and other environmental damage. It is also considered to be more potent than L-ascorbic acid and other Vitamin C compounds, and has a higher rate of penetration (because it is lipid soluble, like human skin) than other derivatives; it also has a higher rate of conversion to vitamin C within the dermis.
