Clinical Trial Summary

This study will evaluate the clinical efficacy, safety and the performance of the BTL-785-2 applicator of the BTL-785F system for non-invasive treatment of facial wrinkles and correcting facial skin laxity.

Description:

The changes in the skin tissue related to the levels of hyaluronic acid (HA) will be assessed histologically. The study is a prospective, single-center, three-arm, open-label study. The subjects will be enrolled and assigned into two treatment groups; group A (RF & USN) and B (only RF) which will receive a treatment with different settings. Subjects of both groups will be required to complete four (4) treatment visits and two follow-up visits. Additionally, a Control will be included to verify the treatment outcomes. At the baseline visit, health status will be assessed. Inclusion and exclusion criteria will be verified and informed consent will be signed. Punch biopsies of the facial skin for the examination of changes related to HA levels and photographs of the treated area will be taken. The treatment administration phase in both treatment groups will consist of four (4) treatment visits, delivered 7 - 14 days apart.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Histological examination	Evaluation of the facial skin tissue to assess the changes related to levels of HA in the biopsies obtained from both treatment groups and control.	5 months
Secondary	Subject Satisfaction	The 5-point Likert scale Subject Satisfaction Questionnaire will be used for evaluating the satisfaction. The Subject Satisfaction Questionnaire will be given to subjects after the last therapy, at 1-month and 3-month follow-up. The answers to the questions related to the subjects' overall skin and face appearance will vary from "strongly agree" to "strongly disagree".	5 months
Secondary	Therapy Comfort	The 5-point Likert scale Therapy Comfort questionnaire will be used for evaluating the comfort during the treatment sessions. Pain sensation will be rated by the subjects from 0 (no pain) to 10 (worst possible pain).	5 months
Secondary	Evaluation of Wrinkle Severity	Three independent evaluators will evaluate changes of wrinkle severity according to the Fitzpatrick Wrinkle and Elastosis Scale (FWES) using the photographs of treated areas for wrinkles (left and right cheeks and the forehead) taken at the baseline, last therapy visit and each follow-up visit. Wrinkle severity improvement according to FWES is considered when there is a decrease in score of the scale. The baseline and post-treatment scores will be compared. If applicable, the statistical significance of obtained results will be analyzed in Microsoft Excel spreadsheet software. The level of significance (a) will be set as 5%.	5 months
Secondary	Evaluation of Overall Facial Appearance According to GAIS	Three evaluators will evaluate facial appearance in the treatment group according to the Global Aesthetic Improvement Scale (GAIS) using the photographs taken at the baseline, last therapy visit and both follow-up visits. Each evaluator will be asked to assign a score to a set of photographs. Facial appearance improvement to GAIS is considered when there is an increase in score of the scale. The baseline and post-treatment scores will be compared. If applicable, the statistical significance of obtained results will be analyzed in Microsoft Excel spreadsheet software. The level of significance (a) will be set as 5%.	5 months
