Ascorbyl Tetraisopalmitate is an oil soluble Vitamin C derivative. It works as a powerful antioxidant and whitening agent, with both anti-acne and anti-aging capabilities. Like other forms of Vitamin C, Ascorbyl Tetraisopalmitate helps prevent cellular aging by inhibiting the cross-linking of collagen, oxidation of proteins, and lipid peroxidation. Ascorbyl Tetraisopalmitate also works synergistically with the antioxidant Vitamin E, and has demonstrated superior percutaneous absorption and stability. Many studies have confirmed the skin lightening, photo-protective, and hydrating effects Ascorbyl Tetraisopalmitate can have on the skin. Ascorbyl Tetraisopalmitate can be found in various skin care products such as anti-aging serums, eye treatments, skin lightening gels and lotions/creams.
