Compared with traditional suture method and Korean suture method, the effect of double eyelid operation is completely different. Oufei's double eyelids pay attention to the fine carving art of surgery, combining aesthetic concepts with the golden ratio of eyes, and the surgery is fine. If necessary, liposuction surgery is performed to make the double eyelid arc smooth and natural, full of layering and three-dimensional sense, as exquisite and beautiful as opening eyes and closing eyes. Although cutting double eyelid surgery is only a minor operation, it is not an ordinary cosmetic operation. It is a plastic surgery for human eyes with traumatic or invasive medical techniques. Therefore, in women's menstrual period, you must not do cosmetic surgery similar to cutting double eyelids. Experts explained that under normal circumstances, the wound after cosmetic surgery should quickly form a blood clot. In the middle stage, the precursor activator of plasminogen increases to the maximum, which can destroy the blood clot in the wound after cosmetic surgery, causing bleeding or prolonged bleeding time, thus causing wound infection in the case of bacterial invasion. Coagulated fibrin and hemolyzed plasminogen precursor activator exist in human blood. Only when these two substances are in balance can human blood flow normally. However, during menstruation, due to the large increase of precursor activator in blood and uterus, women can cause periodic uterine bleeding. In order to prevent wound infection after eyelid surgery, experts suggest that women can have cosmetic surgery only three days after menstruation stops. If it is carried out during menstrual period, take effective antibacterial drugs. In addition, women who take birth control pills should not have cosmetic surgery during taking them, because birth control pills can also lead to an increase in human plasminogen precursor activators.
