简要总结
The objective of this clinical study is to evaluate the efficacy of fractional RF for the treatment and reduction of acne scarring or facial wrinkles.
详细描述
Prospective, single centre, evaluator-blind, split face study of the efficacy of fractional radiofrequency (RF) for the treatment and reduction of acne scarring and facial wrinkles. The study will evaluate the progress of 15 subjects requesting treatment of scarring or facial wrinkles. The study will involve three treatments on both sides of the face with 3-5 week intervals between each treatment. Subjects will be followed at 6 and 12 weeks after their last treatment. Analysis will be performed on all subjects who receive at least one treatment.

结局指标
主要结局
Overall Wrinkle Improvement Assessed by the Fitzpatrick Wrinkle and Elastosis Scale (FWES) at 12 Weeks Post-Final Treatment
时间窗: 12 Weeks Post-Final Treatment
Evaluate the efficacy of overall facial wrinkles improvement assessed live by the Investigator and a subject assessment of facial appearance including the Fitzpatrick Wrinkle and Elastosis Scale (FWES). The FWES is a 9 point scale. Three independent evaluators evaluated before and after photographs and graded them for change. Possible responses were: a score of 1 - 3 (Mild) indicates fine texture changes with subtly accentuated skin lines, a score of 4 - 6 (Moderate) indicates distinct papular elastosis (\[indvidual papules with yellow translucency under direct lighting\] and dyschromia and a score of 7 - 9 (Severe) indicates multipapular and confluent elastosis \[thickened yellow and pallid\] approaching or consistent with cutis rhomboidalis. A lower class and a lower score means a better outcome.
Overall Acne Scar Improvement Assessed by the Global Aesthetic Improvement Scale (GAIS) at 12 Weeks Post-Final Treatment
时间窗: 12 Weeks Post-Final Treatment
Evaluate the efficacy of overall facial acne scar improvement assessed live by the Investigator and a subject assessment of facial appearance including the Global Aesthetic Improvement Scale (GAIS). The Global Aesthetic Improvement Scale is a seven-grade subjective test. Three independent evaluators evaluated before and after photographs and graded them for change. Possible responses were (3) Very Much Improved, (2) Much Improved, (1) Improved, (0) No Change, (-1) Worse, (-2) Much Worse, and (-3) Very Much Worse. For reporting of outcomes, the higher the GAIS value, the greater the improvement (Range -3 to 3).
