The goal of this clinical trial is to determine the BTL-785-7-11 applicator effectiveness for an under-eye appearance improvement by evaluation of the periorbital area in healthy adult volunteers. The main question it aims to answer is:

Whether the BTL-785-7-11 applicator is able to improve the periorbital area post-treatment, as assessed by the analysis of 3D photographs.

Participants will complete four treatments and two follow-up visits.

The study will evaluate the clinical efficacy and safety of the BTL-785 device with applicator BTL-785-7-11 for periorbital area rejuvenation.

The study has a prospective, multicenter, open-label, and one-arm design.

Subjects will be required to complete four (n=4) treatment visits and two (n=2) follow-up visits.

At the baseline visit, inclusion and exclusion criteria will be verified upon obtaining informed consent from the patient. Digital 2D and 3D photographs of the treatment area will be taken.

The treatment administration phase will consist of four (n=4) treatments, delivered 2 -14 days apart. The applicator will be placed outside the orbital rim, on the subject's inferior orbital portion of the orbicularis oculi muscles and lateral canthal edge-temporal area. Therapy time is set to 20 minutes. At the last therapy visit, the subject's digital 2D and 3D photographs of the treatment area will be collected. In addition, subjects will receive therapy comfort and subject satisfaction questionnaires to fill in.

During the 1-month and 3-month follow-up visits, the subjects will undergo 2D and 3D photographing of the treatment area, and the subject satisfaction questionnaires will be collected.

Safety measures will include documentation of adverse events (AE), which will be assessed after each procedure and at all follow-up visits.
