You may notice, after a sleepless night, that swollen bags have formed under your eyes. But why do some people seem to have more than others? The site Live Science asked American dermatologist Carol Clinton about it. The specialist explains that the answer to this question is both genetic (in large part) and environmental.
Bags under the eyes are most often noticed on fair and thin skin. The effects of stress and fatigue are much more visible because blood circulation tends to decrease in this part of the face. The blood tends to clot, the blood vessels stretch, and the eyes become puffy, sometimes surrounded by dark circles. Some people are genetically predisposed to a buildup of fat under the eyeball. In this case, sleeping nine hours a night is no good, all you have to do is curse your DNA.
In other cases, bags under the eyes may be related to temporary factors. The seasonal allergies, for example, stimulate the production of histamines, immune proteins that cause blood vessels in the eyes to swell. Excessive sun exposure can also damage the skin and leave visible marks. And eating very salty can cause Water retention which accentuates the bags under the eyes.
Wearing sunglasses and avoiding rubbing your eyes helps to limit the risks. Sometimes it’s environmental factors beyond our control that play a role, such as gravity. With aging, the levels of collagen and elastin decrease in connective tissue. The bones of the face lose volume and bags form naturally.
