Vitamin K
Vitamin K, at its simplest, helps regulate coagulation. In healthy people, vitamin K ensures that an appropriate amount of blood will clot. A deficiency in Vitamin K could result in excessive bleeding, but often when a person has such a deficiency, there are no ill side effects. Vitamin K is fat soluble, so unlike water-soluble vitamins such as Vitamin C, large doses do not get washed out of the body. It is stored in the liver in small amounts.
Under-Eye Dark Circles
Darkness under the eyes is caused by swollen blood vessels. The blood vessels may become swollen for a variety of reasons, including allergies, sleeplessness, dehydration and injury, to name a few. It is easy to think of what to do when these are the causes. Treat the allergy (or avoid the allergen), get some sleep, drink plenty of water and give your body time to heal. Sometimes, however, dark circles are caused by heredity. Other times, dark circles are inexplicably stubborn and without obvious cause.
Eye Cream
Remember that vitamin K is involved in blood activity, coagulation and anti-coagulation and dark circles under the eyes are caused by broken blood vessels. Vitamin K is a popular alternative medicine to treat bruising. A bruise is coagulated blood under the surface of the skin, often caused by injury. Vitamin K is put in creams that are applied directly to the skin; the theory is that the Vitamin K helps the blood finish its job and the bruise to heal. There is some evidence that a topical cream with vitamin K has the same effect on blood vessels under the eyes. Beauty companies sell under eye creams containing Vitamin K, claiming the cream will lighten the dark circles and make the user look younger. While the is not much scientific evidence to support this theory, many people have claimed success with this method of treating under-eye circles.
