Hylexin is a breakthrough anti-aging product specifically formulated to effectively treat dark under-eye circles. Hylexin is not a concealer, it goes right to the source of the problem. These areas of dark pigmentation are caused by breakage of capillaries in the peri-orbital eye area. Subsequent breakdown of the hemoglobin in the blood causes discoloration, and dark, purplish shading results. Clinical studies have shown Hylexin to dramatically reduce dark under-eye pigmentation by 72%. Hylexin achieves these results by increasing enzymatic action to speed the breakdown of hemoglobin in this area. It is also proactive in strengthening peri-orbital capillaries to stop the leakage of minute amounts of blood.
