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.

微聚焦超声与可视化 (MFU-V) 和钙羟磷灰石真皮填充剂 (CaHA) 均被开发出来，以满足患者对非侵入性但有效的提升和收紧松弛皮肤的需求。最近，人们对使用稀释（1:1）和超稀释（1:≥2）CaHA 来实现皮肤紧致和刺激新胶原蛋白生成越来越感兴趣，并且联合使用不同的技术来获得最佳的美学效果。在这里，两名在 Décolleté 皱纹评估量表上患有 3 级胸部松弛的患者在接受两次治疗后改善了 2 个等级点，因为增加了 MFU-V 治疗的组织层，并在每 100 cm2 增加了额外的一注射器 CaHA。同样，两名在臀部松弛量表上患有 3 级评分的额外患者在接受两到三次治疗后改善了 2 个等级点。在为严重皮肤松弛的患者制定治疗计划时，应考虑 MFU-V 治疗线的数量和深度以及 CaHA 的用量。同样，在治疗臀部和身体其他部位（如臀部）时，考虑体重指数 (BMI) 和体积校正的潜在需求也很重要。J Drugs Dermatol. 2022;21(1):27-30. doi:10.36849/JDD.6368.
