If there are bags under the eyes, you'd better remove them. Different surgical methods are used in different situations, but the purpose of the operation is to repair and strengthen the loose tissue layer. According to the degree of skin relaxation and the anatomical type of eyelid bag, internal incision or external incision can be selected. The former is often used in patients with more orbital septum fat and less obvious skin and muscle relaxation, with rapid postoperative recovery, no incision marks and often no need to remove stitches. The latter is the opposite.
