Vitamin C is a general term for compounds having ascorbic acid activity, including ascorbic acid, dehydroascorbic acid, and its isomers.
USES:
The starting point for synthesis of vitamin C is the selective of oxidation of the sugar compound D-sorbit to L-sorbose using Acetobacter suboxidans bacteria. L-sorbose is then converted to L-ascorbic acid, better known as vitamin C.
vitamin C is a well-known anti-oxidant. Its effect on free-radical formation when topically applied to the skin by means of a cream has not been clearly established. The effectiveness of topical applications has been questioned due to vitamin C's instability (it reacts with water and degrades).
