A VI Peel is a medium-depth chemical peel that penetrates your top layer of skin, called the epidermis, reaching into the dermis underneath. It uses a product trademarked by Vitality Institute Medical Products. Like other chemical peels, a VI Peel works by exfoliating your skin and stimulating the production of new proteins. The procedure is commonly used to treat signs of aging, improve skin texture, and correct pigmentary issues.
