Study Details:
- 15 subjects with mild to severe facial rhytids treated with fractional RF (FRF)
- Single pass treatment (temp. 62 to 78°C, 3-5 sec energy, impedance 300 - 2,000 Ohms)
- 5 evaluators - blinded assessment of photos compared with 6 sets of surgical face-lifts
Study Results:
- Average improvement was 37% of surgical face-lift
- 93% patient satisfaction with FRF treatment
- Mean rating of moderate improvement for rhytids by patient assessment
- Transient side effects with return to normal activities within 24 hours
- Surgical face-lift group experienced scarring and other side effects with 7-10 days downtime
