Treating Striae Distensae Alba with calcium hydroxyapatite and Microfocused Ultrasound

Ten prospectively enrolled women with abdominal, back or thigh SDA were treated with MFU-V at 3 focal depths (4.5, 3.0, and 1.5 mm), followed by 3–6 mL of diluted CaHA+ (1:1 ratio) in the same session. Outcomes were assessed at 1 month, 3 months, and 5 months post procedure using a 5-point quartile grading scale, an SDA scoring scale, a 10-point visual analog score, and a global aesthetic improvement scale. All patients exhibited improvement in SDA at 3 months, with further improvement at 6 months. At the end of the study, all patients were less bothered with their SDA compared with baseline with a mean reduction of 2.7 in visual analog score. All patients were satisfied or very satisfied with the A single combination treatment of MFU-V and diluted CaHA+ improves SDA without side effects and may be considered for patients seeking to minimize SDA.
