Vitamin C (L-Ascorbic Acid) is one of the world’s most potent anti-oxidants. Applied topically to the skin, it effectively attacks free-radicals and evens out the complexion, while improving the appearance of fine lines and wrinkles — all while stimulating the production of collagen! The stability of topical vitamin C potions, however, is always a concern; exposures to air, heat, and/or light degrades its efficacy. The Retro Co. has succeeded in creating a stable form of Vitamin C with its patent-pending multi-chamber delivery system. Mix and C Serum offers an immediate mega dose of fresh-squeezed Vitamin C, which is not only preservative-free, but incredibly potent (15% L-Ascorbic Acid). The pure Vitamin C Powder (an equivalent of five oranges) is separated from the Hyaluronic Serum, and each application is created on-demand by shaking and mixing the two ingredients.
