Puffy eyes can be caused by many factors. These include fluid retention, stress, allergies, hormone changes, and other factors as well. When we cry, it is often accompanied by swollen eyes. The body reacts to emotions and causes more blood to flow through the eyes. This leads to swelling. Also the production of too many emotional tears can strain the eyes. Also, we get puffy eyes after sleeping. This can be caused by different factors such as too much sodium in a diet causing water retention, tossing and turning and not getting enough sleep, excessive drinking of alcohol, and others as well. We have the thinnest skin around our eyes. It's the area that's most influenced by the flow of fluids. A dinner heavy with salty food or a night of crying while watching a tearjerker movie can also cause morning-after puffiness. The reason is osmosis. Water always travels from areas in the body where there's low salt concentration to tissues where there's more salt. That principle holds true whether

When dark shadows or bags linger, the cause typically is not something temporary, like a few too many cocktails. It might be something you've inherited. Pigmentary issues that cause under-eye discoloration are common among people of Asian or African descent. Age also contributes to dark circles. With age, the skin around the eye thins, exposing the tiny blood vessels that lie just below. If you pull the skin sideways and the darkness turns blotchy, that's evidence the problem is caused by excess pigment in the area, says Joseph Eviatar, MD, a New York ophthalmic plastic surgeon. Most often, dark circles aren't about changes in the color of the skin at all. Instead, they're created by a loss of volume in the area around the eye. That exposes the orbital bone, creating a hollow trough that shows up as a dark circle. With the delicate eye area one of the first spots to reveal signs of aging, this can happen as early as the late 30s or 40s.
