The thigh lift is a cosmetic procedure designed to tighten the skin of the thigh and reduce sagging in the inner or outer thigh. Commonly used to treat loose skin, excess fat deposits and stretch marks, a thigh lift is often done after a significant weight loss, and/or in combination with other cosmetic procedures. A thigh lift will tighten the skin and smooth the contour of the inner thigh, generating an aesthetically pleasing result.
