1, incorrect operation method: catgut embedding method is favored by many "cosmetic whites" because of its advantages of less bleeding, quick recovery and low price, but it is precisely because catgut embedding method can not remove skin and fat that the double eyelids formed before the suture protein line is slowly metabolized over time will fall off and become inner double eyelids.

2. Surgical question: Will it definitely not become an inner double after total excision? Of course, the answer is no. Although total cutting is less likely to become an inner double than embedding thread, it is not impossible. If the width of the double eyelids is too narrow, it is easy to become an inner double.

3. In addition, during the operation, if the loose skin and excess fat on the upper eyelid of the eye are not treated too little according to the individual's eye condition, with the slow recovery of the double eyelids, the swollen skin and fat will slowly press to the double eyelid line, which will also cause the consequences of the double eyelids.
