There are many manifestations of facial aging, such as sagging and loose skin, increased wrinkles, loss of elasticity, and increased pigmentation. The often overlooked manifestation is the atrophy and thinning of subcutaneous fat, thus forming local depressions on the face, such as temporal depression, cheek depression, cheek depression and deepening of nasolabial folds. For such symptoms, we can get good results by using autologous fat injection and filling. The fat particles are taken from the parts of the body that are rich in fat and injected into the subcutaneous layer of the sunken area, without surgery, in a short time, with little pain and quick results, and it can also play a role in shaping the liposuction area.
