Study summary

This is a prospective study of 20 Chinese patients with lower facial laxity treated by High Intense focused ultrasound (HIFU). Response will be assessed via paired comparison of pretreatment and posttreatment photographs by two independent dermatologists, grading on a 5-point Subject Global Aesthetic Improvement Scale (SGAIS) for skin laxity. Quantitative analysis of submental lifting will also be performed. Patient's level of "sagging" and "volume loss", satisfaction and tolerance will be documented.

Study arms

  • Experimental
    HIFU

    All participants will be treated using M4.5, level V, with 150 lines on the lower face and submental area; D4.5, level V, 10 Hz, with 4200 dots performed in 7 min on the lower face and the perioral and preauricular areas; M3.0, level V, with 150 lines on the lower face and submental area; D3.0, level V, 10 Hz, with 6000 dots performed in 10 min on the lower face, submental area, and middle face. The microfocused probes were uniformly set to a length of 25 mm with an interval of 1.5 mm. A total of 300 lines and 10,200 dots were performed for each half lower two-thirds of the face and submental area.

    Procedure: HIFU

Interventions

  • ProcedureHIFU

    300 lines and 10,200 dots will be performed to each half lower two-thirds of the face and submental area of every participant.
