Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 7 participants
• Study Classification: INTERVENTIONAL

Brief 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.

Detailed 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.
