Cold water can constrict the blood vessels under the eyes and help reduce eye puffiness and dark circles. Take a washcloth (soaked in cold water or milk) and place it directly over your closed eye ids for several minutes. Alternatively, you can wrap a few ice cubes in a soft napkin and place it under your eyes. Instead of an ice pack, you can also use a bag of frozen peas, a chilled teabag and a cold spoon. Repeat the process three to four times daily for three weeks.
