Vitamin C is an antioxidant and can benefit the skin by reducing wrinkles, improving wound healing, evening skin tones, increasing collagen production, reducing hyper pigmentation and fighting free radicals in the skin.
Vitamin C is naturally present in both the dermis and epidermis, where it limits the damage created by UV light exposure, not like sunscreen, but by protecting the skin against UV-induced free radicals. Besides that, it also plays a role in collagen synthesis, making it a vital molecule for skin health. A decrease in collagen production in the skin can lead to photoaging, pre-mature wrinkles and a change in skin structure. As Vitamin C helps with the hydroxylation of collagen, the extracellular stability and support of the epidermis is improved.
Wound healing is another process that is aided by Vitamin C, as it helps to meet the increased demand for dermal collagen synthesis as the site of the wound, where it also stimulates the formation of the epidermal barrier.
Vitamin C is an essential part of skin health from its small molecular antioxidative properties, to being vital in collagen synthesis. It contributes to photoprotection, decreases photodamage and is needed for adequate wound healing.
