A Study on the Effectiveness and Safety Evaluation of Combination Therapy With 1,927nm Thulium Laser and Fractional Microneedle Radiofrequency Equipment for Improvement of Skin Aging

Not Applicable

Completed

• Conditions: Wrinkle
• Interventions: Device: LUTRONIC GENUS laser(Fractional Microneedle Radiofrequency(FMR)); Device: LASEMED laser(The Thulium laser with 1,927nm wavelength)

• Registration Number: NCT03739398
• Lead Sponsor: Yonsei University

Brief Summary

Fractional Microneedle Radiofrequency (FMR) equipment is a device that penetrates the epidermis and irradiates the high frequency by entering the dermis. The generated radiofrequency transfers heat energy and induces thermal denaturation in the surrounding tissue.

Detailed Description

Using this principle, FMR equipment is being used as a very effective treatment for scarring, enlarged pores, hyperhidrosis as well as wrinkles. Unlike conventional treatments, FMR equipment has the advantage of a short recovery time after treatment because it minimizes damage to the epidermis because the insulated microspheres penetrate the skin and generate high frequency only at the end of the microspheres.

The Thulium laser with 1,927nm wavelength is a device that effectively removes various skin diseases present in the epidermis while minimizing the side effects such as scarring and pigmentation because it induces thermal damage to the only skin surface compared to conventional laser equipment. In recent years, not only skin lesions on the epidermis but also pigment disease and wrinkles have been reported to have a good effect.

In this study, investigator investigated the effect and stability of combined treatment of Thulium laser with 1,927nm wavelength in addition to FMR equipment which has already proven to be effective in improving skin aging.
