Arms Assigned Interventions
Experimental: 1 Device: GFX System
The GFX system employs minimally invasive technique utilizing bi-polar radio frequency (RF) technology. GFX ablates nerves activating the muscles that cause glabellar furrowing.
Other Name: Radio Frequency Ablation

Detailed Description:

The purpose of this research study is to evaluate the acute ability of GFX to reduce glabellar furrowing.

Patients who have presented to the investigator for correction of glabellar furrows, as classified per the Rated Numeric Kinetic Line Scale Score for Facial Wrinkles Secondary to Hyperkinetic Function (Note: Class 1 or Higher)7 (Appendix N) are candidates for this study. All patients must consent to the procedure and agree to complete their post treatment evaluation visit.
