简要总结
Non-invasive treatment options such as focused ultrasound has been used with success for the treatment of skin laxity in various parts of the body including the face, neck, décolletage, arms, buttocks, thighs, and legs. With the increasing demand for greater results, researchers have started combining modalities together such as focused ultrasound and intradermal filler, with promising effects for skin laxity and volume restoration. This study aims to elucidate the efficacy and added benefits of a combination therapy using focused ultrasound (Ulthera) and calcium hydroxylapatite (Radiesse) for the treatment of skin laxity and volume restoration of the lower thighs, specifically the lower anterior third of the thigh.
