Outcome Measures
Primary Outcomes (1)
Time at which the patient no longer shows an improvement from the base line RNKLS score indicating that the initially successful GFX procedure is no longer effective at a scheduled follow-up visit.
18 months
Secondary Outcomes (1)
Minimal or transient incidence of minor unanticipated adverse events.
30 days
Study Arms (1)

EXPERIMENTALPatients 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 R) are candidates for this study.
Interventions
The GFX system employs minimally invasive technique utilizing Bi-polar (radio frequency) RF technology. GFX ablates nerves activating the muscles that cause glabellar furrowing.
Eligibility Criteria

- Has no medical contraindication
- Presents for correction of glabellar furrows, as classified per the Rated Numeric Kinetic Line Scale Score for Facial Wrinkles Secondary to Hyperkinetic Function (Class 1 or Higher)
- Is at least 18 years of age
- Signs a written informed consent
- Understands and accepts the obligation to present for scheduled follow-up visits
- Understands that the GFX procedure may not be successful
- Presents at the one month follow-up visit with an improvement from the base line RNKLS score
You may not qualify if:
- Has had an injection of botulinum toxin to the target area within the previous 4 months and still exhibits a positive cosmetic effect to the glabellar frown.
- Has had silicone, fat, collagen or a synthetic material placed in the glabellar region or surgical correction or excision of the glabellar furrows
- Has a known bleeding disorder

- Has known lidocaine hypersensitivity
- Is enrolled in another study
- Has history of keloid formation
