effects of using vitamin c on skin
Vitamin C Serum Side Effects. Since vitamin C is an acid, the low pH can irritate your skin if you start using a lot of it too fast. In some cases, sensitive skin can even get mild chemical burns and the skin can be prone to peeling in the first few days when you start using a strong vitamin C serum.
Vitamin C is one of the most powerful antioxidants in skin care. It helps slow down the aging process by preventing free radical damage. Long-term topical use has been clinically shown to regenerate collagen and improve the appearance of wrinkles. Vitamin C also lightens pigmentation and brightens over all skin tone. Therefore, it is used in a lot of anti-aging and whitening products (especially in Asia), as well as fade creams.
Vitamin C also helps create scar tissue and ligaments, and it helps your skin repair itself [source: Milton S. Hershey Medical Center]. Vitamin C is an antioxidant that slows the rate of free-radical damage -- free radicals are unstable molecules that damage collagen and cause skin dryness, fine lines and wrinkles.
That's because vitamin C, also known as ascorbic acid, is key to the production of collagen, a protein that aids in the growth of cells and blood vessels and gives skin its firmness and strength [source: WebMD].
