TimeWise Replenishing Serum C+E ® 44ml x2 Rose Quartz Facial Roller Massager Vitamin C is great for skin. So is vitamin E. Put them together, and you’ve created something truly extraordinary. This “better together” pairing of two super-antioxidants in TimeWise Replenishing Serum C+E™ is supported by decades of scientific research demonstrating how this interaction improves antioxidant performance. Daily use delivers skin that’s firmer, brighter – glowing with good health. Vitamin E, a highly potent antioxidant critical for protecting against premature skin aging, is depleted as it fights damaging free radicals. When paired with vitamin C, it receives a boost that reignites its age-fighting power. With this formula, Mary Kay scientists have leveraged this dynamic cycle of replenishment to do even more for your skin.
