Vitamin C 20 % Face serums are specialists designed to deliver a high concentration of vitamin C. Although the formula is oil-and-water-based, it is created to have an oil-free texture. In fact, serums are described as having a velvety finish. Although the formulas do not leave an oily finish, the intensive formula can irritate sensitive skin. People with sensitive skin should look for vitamin C serums.
