For ordinary people, there are several reasons for this situation. One is that it was designed before it was finished. The other has nothing to do with the aesthetics and technology of the hospital. The other is that it is not suitable or necessary to cut at all.
The first two are easy to understand, why some people are ugly or even ugly after cutting, mainly because they don't have the conditions to cut double eyelids.
In fact, it is very important to have good eyes. A key condition for good eyes is that the pupil is exposed to at least 80%.
Good-looking single eyelids basically cover the pupils very slightly. If you cover your pupils very high, even your double eyelids are often criticized for being dull.
The degree of transformation can be achieved by cutting double eyelids. Basically, there are problems of pupil occlusion, eyelid relaxation or swelling. It turned out that the eyelids were tight and did not cover the pupils. Adding double eyelids won't change much. Therefore, evaluate your own conditions reasonably, and don't expect a double eyelid to complete Barbara's little magic transformation. Especially for patients with obsessive-compulsive disorder, cosmetic surgery is not recommended, which is a kind of torture for themselves, including doctors. Born with asymmetrical eyelids, few stars love beans.
