Caffeine is an excellent vascular toner that helps to drain the eye contour area by stimulating microcirculation. By narrowing the diameter of small blood vessels, the purplish pigmentation of dark circles, caused by the color of the blood capillaries, is durably reduced. Additionally, caffeine has antioxidant properties. It helps protect cells against free radicals generated by UV radiation and slows down the process of photoaging of the skin.
