Especially for girls who like to wear makeup, double eyelid eye shape makeup keeps more lasting and the eyes are more colorful. At present, whether we open a newspaper or visit a website, we will find “double eyelid” advertisements all over the place. The “polymer double eyelid”, “PC positioning”, “biological welding”, “Korean minimally invasive”, and “Korean scarless” are all advertised. “These non-medical advertising terms are full of temptation for girls who intend to have double eyelid surgery, as if high technology, high level and high technique are in it. In fact, these terms are just a means to attract the public’s attention and a tool for businessmen to make profits. So, from a medical point of view, how are double eyelids actually formed? Fundamentally, it is due to the distribution of the muscles and tendons that lift the eyelids part of the eyelids, and when the muscles contract, that is, when we open our eyes, the skin crease is formed, that is, double eyelids. Therefore, the starting point for our double eyelids is to make the muscle tendon membrane of the eyelid lift form adhesions with the skin. For people with tight eyelid skin and thin eyelids, the “buried wire method” can be used to create double eyelids. In this procedure, a 1mm incision is made on the outside of the eyelid, and medical nylon sutures are placed between the skin and the musculotendinous membrane to form the adhesions that form the double eyelid. In advertising language, “polymer double eyelid”, “PC positioning”, “biological welding”, etc. belong to this category. The “Korean minimally invasive” and “Korean scarless” methods refer to making three small openings of about 3mm on the eyelid and removing part of the orbicularis oculi muscle under the skin in order to form adhesions between the muscle tendons of the eyelid lift and the skin. For people with looser eyelid skin and bloated eyelids, the preferred surgical method is the incisional method of double eyelid. This method involves designing the eyelid line 6-8mm from the lid margin, properly removing the loose skin, some of the muscle and fat tissue under the skin, and fixing the skin to the muscle tendon membrane of the eyelid lift to form a double eyelid. The recovery time for double eyelid surgery is about 2-3 weeks and may vary depending on the skill level of the surgeon and the ability of the autologous tissue to recover. We hope that every girl who loves beauty can find the right surgery method for herself and a good doctor who is serious and responsible for you, so that she can get a perfect surgery result and have a pair of beautiful double eyelids.
