What makes the Vitamin C in VI Derm Vitamin C Brightening Concentrate better than other Vitamin C?

Typically, many of the Vitamin C products you see on the market are made with L-ascorbic acid. While L-ascorbic acid is an amazing type of Vitamin C, it is very finicky and oxidizes quickly if not formulated and storied in optimal conditions. The Vitamin C we use is clinical strength 10% tetrahexyldecyl ascorbate, which is a Vitamin C that is much more stable and potent that the typical L-ascorbic acid. In addition, we formulate our Vitamin C Brightening Concentrate with NO water and in an airless pump, which ensures the freshest, most potent formula for much longer.
