According to experts, everyone's conditions are different, so this problem should not be generalized. For many people, it only takes 5~7 days, and a very natural effect can be achieved by sewing, and the trouble of taking out stitches is also avoided. However, if the upper eyelid belongs to the bleb with fat hypertrophy, some fat should be removed first to create a three-dimensional effect of the eye before operation. In this way, the postoperative recovery period will be one or two days longer than that of simple suture. Generally speaking, double eyelid surgery's choice does not need to focus on sewing or opening, and the width of double eyelids is not so-called popularization. Successful eye plastic surgery must focus on shaping the three-dimensional sense around the eyes, in line with the proportion of the face. If the eyelid is too thick, remove the fat first, if the orbit is too sunken, fill it moderately, and if the eyelid is slack, remove the fat first. Then, according to the eye shape and the distance between the eyebrows, design the double eyelids with appropriate width, and use open double eyelids when necessary to adjust the proportion of eyes to the whole face. The existence of cosmetic surgery is to satisfy the psychology of human beings' love of beauty, to add points to the original conditions, and to obtain the best results at the least cost. As long as you master the two keys of overall aesthetic feeling and natural rendering, whether sewing, cutting or various innovative methods are recommended. Therefore, the choice of cutting double eyelids or sewing double eyelids should be analyzed according to the actual situation of the individual, and it is not possible to say which is good or not in general. The most important thing is appropriateness, and appropriateness is the best.
