Nowadays, many girls pay more and more attention to the charm of eyes. So many girls with single eyelids cut their double eyelids, and then they look energetic and beautiful, all of which increase their confidence. However, some people's double eyelids are not effective, giving people a stiff feeling and losing their original charm. It can be seen that not everyone is suitable for cutting double eyelids. The following kinds of people should not cut double eyelids. (1) Round face. Some girls with single eyelids and apple faces have small eyes when they smile. If the five senses are properly matched, it will give people a sweet feeling. Obviously, even if you don't do double eyelid surgery, this aesthetic feeling still exists. It is unnecessary to do double eyelids, and even bring lifelong regret. (2) round eyes. Round eyes themselves don't give people the feeling that their eyes are very small, and the width from top to bottom exceeds that of ordinary eyes. If you do double eyelids, it is likely to give people the feeling of hanging eyes. (3) people with swollen eyes. The swelling of the ball is due to the thick deposition of subcutaneous tissue in the eye, which gives people a feeling of edema. This kind of eyes is not beautiful in itself. If you add an eyelid, it will make the swollen eye bubbles more redundant, so let it be. (4) goldfish eyes. People with goldfish eyes have prominent eyeballs. If they have double eyelids, they will inevitably feel that their eyeballs are more and more prominent, which will highlight their ugliness and outweigh the benefits. It's cheap to cut double eyelids. In order to make myself more beautiful, I spent more than 200 yuan to cut my double eyelids. I didn't expect a small pimple to grow on my eyelids after the operation. One year later, I had my eyebrows removed, and I found another doctor to get rid of the acne, but after the operation, I got a few more acne, no matter who I looked for. The experience of Ms. Zhou, who works in Ann, once again sounded the alarm for beauty lovers: be careful when cutting your face. Do you know how double eyelids are formed? There is a small and thin muscle in the deep part of eyelid, called levator palpebrae superioris. When it contracts, the upper eyelid lifts and the eyes open. Part of its muscle fibers can stop at the skin of the upper eyelid. When you open your eyes, due to the tension of this part of muscle fibers, the skin of the upper eyelid produces a wrinkle, which is the double eyelid. There are some yellow people who don't have such muscle fibers to reach the skin under the upper eyelid. These people are single eyelids. There are many ways to change a single eyelid into a double eyelid. Surgical formation of double eyelid plasty. Double eyelid plasty is divided into incision and suture, and their basic principle is the same, that is, trauma is caused between the upper eyelid skin and the tarsal plate or levator palpebrae aponeurosis, forming scar adhesion. If the scar is not firmly adhered, the double eyelids will disappear. Not all people with single eyelids are suitable for double eyelids, and not all people who have cut double eyelids will be satisfied with the operation. Constraints include: (1) the design of surgical incision. It is directly related to the surgical effect. The design of incision position is closely related to the patient's requirements and the doctor's aesthetics, so patients should have a serious discussion with plastic surgeons before operation to avoid differences due to different understanding of postoperative results. (2) the patient's own conditions. Some patients want to do double eyelid plastic surgery, but their own conditions are not good enough and the effect is poor. For example, after double eyelid surgery, patients with exophthalmos may become speechless and serious because of changes in appearance. Such factors also include: patients with small eyes, close distance between eyes, too much fat on eyebrows and upper eyelid margin, and loose upper eyelid skin. These factors should be carefully considered before operation. (3) Patients with scar constitution should not do this kind of operation, otherwise it will cause scar hyperplasia after operation and destroy the cosmetic effect. (4) If there are facial infections, such as folliculitis and acne, these diseases should be cured first, and then facial plastic surgery should be considered. (5) Patients with binocular conjunctivitis should be treated with eye diseases first, and then treated with double eyelid surgery. (6) It is best not to have surgery during menstruation. Due to more bleeding during the operation, the local swelling time after the operation is long and the reaction is heavy, which affects the operation effect. Therefore, it is best to arrange the operation three or four days after menstruation is clean. Finally, another important factor is the quality of plastic surgeons.
