Vitamin C Absorption

Vitamin C is the most abundant antioxidant within the skin. It repairs damage caused by free radicals and is essential for collagen production. Vitamin C is also a popular ingredient found in skin care creams and some formulations can absorb transdermally (through the skin). However, it's up for debate whether or not Vitamin C is beneficial as a topical agent.

There is no solid proof that vitamin C creams reduce wrinkles or slow down the aging process; although there are plenty of anecdotal testimonials to that affect. Animal studies have shown vitamin C applications to minimize the damage caused by UV exposure. Another recent study suggests that applying topical vitamin C after sun exposure can initiate skin repair. Vitamin C has also been shown to reduce redness due to rosacea and to improve skin tone.

Usually skin creams contain other emollients and ingredients that are beneficial to the skin, so it is difficult to determine whether vitamin C alone has a positive effect.
