The methods to improve the sunken face mainly include injectable filler treatment and surgical treatment. 1. Injection filler treatment: choose hyaluronic acid and autologous fat as filler materials, and inject filler to local skin, which can restore local skin to normal level. After the treatment, it is necessary to pay attention to strengthening skin care, avoiding massage and extrusion within one week. 2. Surgical treatment: If the sunken face is caused by abnormal bone structure, surgical treatment is available, and you need to consult a plastic surgeon or orthopedic surgeon for details. Due to individual differences in clinical manifestations, it is important to consult a doctor before choosing a treatment.
