Hello, there are three common double eyelid methods: double eyelid incision, double eyelid catgut embedding and Korean minimally invasive double eyelid surgery. The embedding period of catgut is 3- 10 years, which varies from person to person and is suitable for people with thin upper eyelids. Incision and minimally invasive surgery are permanent, suitable for a wide range of people, large and small eyes, eyelid swelling, internal eyes and so on. It is suggested to choose a suitable method for surgery after face-to-face consultation in a regular plastic surgery hospital.
