Skin sagging is a possible complication after surgery, but not all patients will experience this. Skin sagging occurs when the skin drapes over a bone which is reduced or changed. However, skin sagging can also occur because of aging, even if a patient doesn’t undergo bone surgery. This can be prevented by choosing a surgery plan which doesn’t affect skin elasticity or muscle condition. Furthermore, a thread lift can be a good alternative to prevent skin sagging, as the thread holds the skin during the recovery process.
