Super C Serum contains a stabilized oil-soluble form of Vitamin C, called Tetrahexyldecyl Ascorbate, that causes little to no visible irritation on the skin with increased effectiveness for visible results. Tetrahexyldecyl Ascorbate can benefit the skin at a percentage as low as 0.5%. Most other forms of Vitamin C, such as Ascorbic Acid, need around 15% to promote visible results. Based on clinical studies, Verso Super C Serum is formulated with 3% to optimize the visible brightening effects. With pH like our sebum, the skin's natural oil, the ingredient may alleviate the appearance of temporary redness or discomfort. Together with Vitamin E, the formula enhances natural skin protection and promotes visible radiance and smoothness. Furthermore, this serum includes an extract from the Australian super-fruit Kakadu Plum, the world's richest source of Vitamin C. It has approximately a hundred times more Vitamin C than an orange. Kakadu Plum promotes radiant and youthful-looking skin with antioxidant properties. Another key ingredient is Phloretin, derived from apples. The plant-based ingredient has strong antioxidant properties minimizing the appearance of fine lines and wrinkles while visibly calming the skin. Tetrahexyldecyl Ascorbate pair well with Vitamin A for enhanced results."
