How to turn single eyelids into double eyelids? Now look around you or look through your family photos, count how many of your friends and relatives are single eyelids, and how many of them are double eyelids, but will “turn back” to single eyelids with the opening of the eyes. You will find that more than half of them are among the above two cases. What is the reason for this, and why do most European and American people have double eyelids? Because we are yellow, most of the development process did not form “double eyelids that line”, that is, the medical heavy eyelid crease, so “small-eyed beauty” and “small-eyed handsome” This is why “small-eyed beauties” and “small-eyed men” are basically found in East Asia, including our country. To know how to turn single eyelids into double eyelids, you have to start with the principle of natural double eyelid formation. In a normal person, the power to open the eyes comes from a muscle called the levator muscle, which is attached to the lid plate, and the muscle contracts to open the eyes. In people with double eyelids, a portion of the levator muscle branches out and connects to the skin of the upper eyelid, so that the contraction of the levator muscle not only lifts the eyelid but also moves the attached skin upward when the eye is opened, resulting in natural double eyelids. People with single eyelids do not have this important “branch”. Therefore, if we can create such a branch or create the same effect as this branch, we can artificially create double eyelids. There are two ways to create double eyelids: the incision method and the buried line method. The oriental eyelid anatomy is characterized by thick eyelids, loose fascial tissue wrapped in fat, more fat in the orbital septum, and a thin levator tendon membrane. The common “swollen eyelid” is a typical example of an oriental eye, which is caused by excess fat in the orbital septum or downward prolapse. Because of the above characteristics of the oriental eye, the main reason for double eyelid surgery for oriental people is the incision method which removes excess skin and fat. The buried line method has the following requirements for the eye shape of the candidate: no obvious drooping of the upper eyelid (not much skin), not swollen eyes (no fat removal), and strong eye opening (no upper lid drooping), all three of which can be considered for the buried line double eyelid. But on the other hand, if a candidate can do the buried eyelid method, then she must also be suitable for the incision method, which means that the incision method is suitable for everyone, but the buried line is much harsher. In recent years, because of the dual requirements of minimally invasive and aesthetically pleasing, plastic surgeons have combined the two methods and invented a “combination procedure”, that is, for people who have swollen eyeballs but are afraid of surgical incision, they can first open a 2-3mm incision in the outer part of the upper lid, remove some of the excess fat through the incision, and then do the traditional The traditional buried eyelid method is used. In short, the final decision on the surgical method is neither the plastic surgeon nor the candidate himself, but the actual situation of the candidate and the current level of medical technology. What kind of people are not suitable for double eyelid surgery? The actual surgery is not suitable for people with acute or chronic inflammation of the eyes, such as conjunctivitis keratitis, wheals, and so on. In addition, patients who have unrealistic ideas about the results of surgery are also contraindicated, such as those who take a picture of a celebrity and ask the surgeon to make her eyes look like a celebrity, but their basic conditions are not suitable.
