When the upper or lower eyelids are puffy, the eyes can look swollen and the overall impression can seem tired. After crying or sleeping after eating ramen, the swelling often seems to be 2–3 times worse than other people’s, which can be stressful. Certainly, people with prominent under-eye fat can look irritable or tired.

Usually, when you look at the families of people with prominent under-eye fat, many of their parents or siblings also have prominent under-eyes. Perhaps the whole family is tired. This under-eye fat can be corrected surgically by removing the under-eye fat that pushes forward through the lower eyelid septum and fixing the remaining fat to the periosteum so that it no longer protrudes, thereby eliminating the bulge under the eyes.

In the past, some people had only #lowereyelidfatremoval, and after a few years the fat that had been inside would push forward again, causing the area to become bulgy once more. More recently, after removing the under-eye fat, #lowereyelidfatrepositioning is performed so that the inner fat no longer pushes forward and makes the under-eye area bulge again. Of course, if the bulge under the eyes is not severe and there is not much under-eye fat, improvement may be possible with repositioning alone without fat removal.
Lower eyelid fat repositioning
Usually, a surgical technique that fixes the fat to the periosteum after lower eyelid fat removal so that the fat no longer protrudes

Unlike #lowereyelidsurgery, which is often done in people in their 50s and older, those with a family history often already have prominent under-eye fat from a young age, so it is common to undergo lower eyelid fat removal or lower eyelid fat repositioning in their 20s. Even without a family history, the under-eye fat often starts to protrude noticeably from the late 30s, so lower eyelid fat repositioning is also commonly performed in the 30s and 40s.
If you look in the mirror one day and suddenly feel that you look tired and older for some reason, please check whether lower eyelid fat removal or lower eyelid fat repositioning may be needed!
