Vitamin K. As the nutrient responsible for helping blood clot, Vitamin K won't do much for your skin from the inside. But studies presented to the American Academy of Dermatology in 2003 showed that topical vitamin K works well to reduce circles under the eye as well as bruises. In research published in the Journal of the American Academy of Dermatology in 2002, doctors from the University of Miami School of Medicine found that skin treatments with vitamin K cream after laser surgery significantly reduced bruising. When combined with vitamin A in a cream, vitamin K can be even more effective for those dark circles. In a study published in the Journal of Cosmetic Dermatology, doctors from the Nippon Medical School in Tokyo found that the topical application of a gel containing a derivative of vitamin K, as well as vitamins A, C, and E, was effective in reducing dark under-eye circles while also decreasing wrinkles.
