An Exceptionally-Stable, Direct-Acting Form of Vitamin C An exceptionally-stable solution of 15% Ethylated Ascorbic Acid, this water-free formula offers a direct-acting approach to achieving a radiant, healthy-looking skin tone. Unlike other Vitamin C derivatives, this ethylated form acts directly like Vitamin C, is closer in molecular weight to actual Vitamin C which allows for faster visible results, and offers a much better stability profile than any known direct-acting form of Vitamin C. Notes: Since this formulation is a water-free solution, it may feel slightly "oily" for a few seconds after application, despite the absence of all oils. Directions Apply a few drops to face AM and PM. Avoid contact with eyes. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children.
