Congenital reasons: Due to congenital genetic problems, the skull is slightly concave, so on the surface, the temple will be concave. Due to the excessive pursuit of weight loss, body fat is reduced and enters a slimming state. With the increase of age, collagen is lost and subcutaneous tissue becomes smaller, which leads to temple depression. There are three ways to repair the sunken temple. Baizhitang massages the temple and insists on injecting hyaluronic acid into the temple, but the effect is not lasting. Autologous fat transplantation is needed every six months, which is effective but risky.
