Named Best Vitamin C Serum by Allure and Harper's Bazaar and Best Dark Spot Corrector by Cosmo, Universal C Skin Refiner from BeautyStat Cosmetics is an age-defying treatment for brighter, firmer, more even-looking skin. Formulated with 20% pure vitamin C and three patents, this serum offers a stable full strength formula with no color change or loss of effectiveness from the first pump to last. This lightweight gel-cream immediately provides smoother, silkier, more radiant and pore-less skin with no ugly brown color change or loss of effectiveness. Over time, lines, wrinkles, redness and dark spots are reduced. While many products contain a form of vitamin C, this ingredient is difficult to contain and stabilize within formulas. BeautySTAT did comparison stability testing versus leading competitor vitamin C products and the Universal C Skin Refiner remains pure and active; other formulas oxidize, turning orange or brown.
