Internal incision, that is, liposuction under the eyes, is suitable for young people without obvious relaxation of the skin. It removes excess orbital septum fat through a small incision in the conjunctival sac of the lower eyelid, and there is no incision mark on the skin surface after operation. The external cutting method is thorough, which greatly improves the bags under the eyes and wrinkles. Suitable for older people with loose skin and more wrinkles. It cuts the orbicularis oculi muscle from the lower margin of the lower eyelid eyelashes in turn, removes excess fat and loose skin after opening the orbital septum, and finally stitches the wound and tightens the skin. Postoperative marks are not obvious.
