VITAMIN C
A fundamental nutrient for several vital functions, it has powerful antioxidant action that helps protect skin cells against the effects of free radicals, such as those caused by exposure to solar radiation.
As the human body cannot synthesize it, it depends on obtaining vitamin C from external sources, including through topical application, as even high doses of oral supplementation cannot provide an adequate amount of vitamin C to the skin.
There are different forms of vitamin C, the only biologically active one being ascorbic acid, a molecule that is unstable at neutral pH and has a high tendency to oxidize. Other forms, known as derivatives, have greater stability and less propensity to oxidation, and can be converted into ascorbic acid when in contact with the skin.
There are several scientifically proven benefits of vitamin C, such as stimulating the production of collagen and fibroblasts, helping to form a skin barrier and reducing skin hyperpigmentation.
