The Science Behind
“It is exceptionally difficult to formulate a long-lasting vitamin C serum that will keep its power over time. Vitamin C is notoriously unstable, sensitive to oxidation and can often turn yellow in color, which indicates that it has gone off. Medik8’s C-Tetra range utilizes a stabilized form of vitamin C, called tetrahexyldecyl ascorbate. This molecule is altered to make it less reactive to oxidation, meaning that even 6 months down the line you can be sure your vitamin C is still as potent as when you first opened it.”
