Vitamin C when applied topically to the skin can reduce both photo aging and chronological aging. Vitamin C is a major line of defence against reduced Collagen production and therefore is critical in the treatment of aging. As we age and Collagen levels are reduced, there is also a gradual reduction of Hyaluronic acid, the product needed for moisture retention. Vitamin C is also a Tyrosinase inhibitor, the enzyme that triggers the production of Melanin. The use of Vitamin C serum in your daily skin care regime and particularly when combined with gentle Lactic acid peels, is effective in reducing the appearance of unwanted pigment on the skin.
