Casabona G, et al. - An inquiry was set up with regard to the combined use of microfocused ultrasound with visualization (MFU-V; Ultherapy) and diluted calcium hydroxylapatite (CaHA; Radiesse) for treating skin laxity and wrinkling on the neck and decolletage. Findings illustrated that the combination of MFU-V with 1:1 diluted CaHA was effective for the improvement of the appearance of neck and decolletage lines and wrinkles.
