But why did people have these dark purple bags under their eyes in the first place? Dr Carol Clinton, a skin care expert at Timeless skin Solutions in Dublin, Ohio, said that the answer is heredity (that is, it is related to your DNA) and environment (the result of daily life, such as rubbing your eyes or getting too little sleep), but "heredity is the biggest culprit", Clinton told Life Science.

Due to genetic reasons, bags under the eyes are usually more obvious for people with thin or pale skin. That's because it's hard for a white face to hide everything behind it. Clinton said that when people feel tired or stressed, the blood circulation in their eyes tends to slow down, which makes blood gather in their eyes. She said that capillaries (capillaries) dilate and leak, leading to edema and dark circles.
In addition, some people are genetically prone to subluxation, and fat moves from the eyeball to the eye. (It is worth noting that a study published in the Journal of Plastic and Reconstructive Surgery in 2008 showed that bags under the eyes were not caused by the development of existing fat, but by the aging of fat under the eyeball. In any case, Clinton said, when the fat moves forward, people will consider having surgery in that area. She added that subluxation has nothing to do with a person's sleep time. In other words, a person can sleep for nine hours every night, but he still has bags under his eyes because of genetic factors, Clinton said.
In other cases, environmental factors can cause eye edema. For example, allergies-especially seasonal allergies-can lead to capillary leakage, Clinton said. When the body comes into contact with allergens, it releases an immune protein called histamine. She said that these substances can cause blood vessels inside and outside the eyes to swell.
Clinton said that too much sun exposure can also damage the skin, make it thinner and make dark circles more obvious. Besides, according to the Mayo Clinic, eating salty food will make the body retain more water and aggravate the bags under the eyes.
In addition, rubbing your eyes can also cause dark circles, because this action will * * * easily leak capillaries. To avoid the urge to rub your eyes, Clinton said, when your closed eyes feel itchy, try to ice them for 60 to 90 seconds.
"Cold compress will constrict blood vessels, and it will stop itching," Clinton said. "You will notice immediate relief.
Sometimes, uncontrollable environmental factors, including gravity, can cause bags under the eyes. With the increase of age, collagen (a structural protein) and elastin (an elastin) in connective tissue will be lost. Clinton said that as you get older, the bones on your face will lose their volume, so "everything will hang on your face", which will also lead to bags under your eyes.
