Combined Calcium Hydroxylapatite Plus Microfocused Ultrasound for Treating Skin Laxity of the Chest and Buttocks.

Microfocused ultrasound with visualization (MFU-V) and a calcium hydroxylapatite dermal filler (CaHA) were both developed to meet the patient demand for a noninvasive but effective means for lifting and tightening of lax skin. Recently, there has been growing interest in the use of dilute (1:1) and hyperdilute (1:≥2) CaHA to achieve skin tightening and stimulating neocollagenesis, and the combined use of difference techniques to obtain optimum aesthetic outcomes. Here, two patients with Grade 3 chest laxity on the Décolleté Wrinkling Assessment scale improved by 2 grade points after two treatment sessions because increasing the tissue layers treated with MFU-V and adding an additional syringe of CaHA per 100 cm2. Similarly, two addition patients with Grade 3 scores on the Gluteus Laxity Scale improved by 2 grade points after two or three treatment sessions. Customizing the number and depth of MFU-V treatment lines and the amount of CaHA should be considered when making a treatment plan for patients with severe skin laxity. Similarly, it is important to consider body mass index (BMI) when treating body areas such as the gluteus and the potential need for volume correction.
