Sagging skin and serious wrinkles can be treated with Thermage and Facial Tightening as prescribed by the doctor. 1. Thermage: Thermage is a radiofrequency treatment that stimulates the deeper layers of the skin to promote collagen remodeling and improve the symptoms of sagging skin and severe lines, making the skin tighter. 2. Facial Lift: Patients can also undergo a facial lift, in which loose facial skin can be lifted and tightened, and excess skin can be removed to improve the symptoms of sagging skin and severe lines. Generally, there is no need to treat loose skin and serious lines, but if it affects the aesthetics, it is recommended to go to the hospital for consultation and choose the appropriate treatment under the guidance of the doctor.
