Vitamin C is an essential nutriment for humans. Vitamin C is known for its antioxidant potential. Vitamin C acts as a potent water-soluble antioxidant in biological fluids. Thus, topical vitamin C will not only reduce the risks of development of photoaging but also could reduce the risk of carcinogenesis. In addition to its antioxidant properties, vitamin C is essential for collagen synthesis. Vitamin C stimulates or restores several mechanisms which are either deficient or disturbed. Topical application of vitamin C partially restores the anatomical structure of the epidermal-dermal junction in young skin. A clinical trial confirmed for the first time that topical application of 5% vitamin C over a period of 6 months significantly improves the clinical appearance of photodamaged skin when compared to the vehicle alone. In inflammatory skin diseases, that is, atopic dermatitis and psoriasis, vitamin C levels into the dermis are reduced. Moreover, a randomized double-blind comparative study conducted in patients with Bateman purpura showed a significant improvement that vitamin C is probably one of the main topical anti-aging agents. In addition, the use of photo-protective sunscreen after UV irradiation prevents the decrease of acid ascorbic dermis concentration. Indeed, the ingestion of vitamin C has different benefits on skin such as wound healing, cutaneous aging, and prevention of skin cancer.
