First, the cheeks are sunken and filled: the cheeks are sunken, which is more common in thin people, with less subcutaneous fat and less cheek fat pad, which is characterized by "cheekbones", which is an old-fashioned look. The filling method of buccal depression is similar to that of temporal depression. However, because the buccal filler is placed directly under the skin, it is easy to contact outside the skin, so the characteristics of the filler are high, and hard materials such as silica gel are difficult to be applied here. Polytetrafluoroethylene is better, but it still feels hard. The incision is selected at the edge of tragus, and a cavity with appropriate size is divided forward under the skin. Fill in, flatten, suture the wound, and take out stitches after 5-7 days. It can also be filled with dermal fat or autologous fat particles, with good effect. Second, eyelid depression filling: upper and lower eyelid depression refers to different degrees of eye socket depression caused by the shortage and atrophy of soft tissue between upper and lower eyelids and orbital margin. It is observed that more than one-third of people will begin to shrink the fat of the upper eyelid after entering middle age. Its symptoms are as follows: after evening, eyelids feel heavy, eyes feel tired and dry; However, some people began such changes in their twenties because of their physique and heredity.
