Many people think that the eyes with double eyelids look big and divine, while those with single eyelids in the East are mostly, so cutting double eyelids has become the most common surgery in the East. But only people with long eyes, thin skin and high nose have the best effect. A successful double eyelid plastic surgery has the following points: the width of double eyelids is appropriate; The radian is commensurate with the radian of the upper eyelid and the face shape; Incision scar is not obvious; The lines of double eyelids are natural. The success of double eyelid surgery is not only related to the surgeon's aesthetic views and cosmetic techniques, but also related to the patient's eye shape, anatomical structure and facial morphology. Because the cosmetic surgery in China is not standardized, some cosmetic surgeons or beauty salons do not have the corresponding level and conditions. During the operation, no matter what the patient's condition is, one method is invariably used, and the result is very unsatisfactory. Therefore, the subjects must think twice before doing this operation.
