Prospective, single centre, evaluator-blind study of the safety and performance of fractional radiofrequency (RF) for the treatment and reduction of acne scarring. The study will evaluate the progress of 15 subjects requesting treatment of acne scarring. The study will involve three treatments on both sides of the face with 3-5 week intervals between each treatment. Subjects will be followed at 6 and 12 weeks after their last treatment. Analysis will be performed on all subjects who receive at least one treatment.
The Venus Viva™ fractional RF device has been shown in clinical studies to improve various skin conditions related to aging and alter collagen structures such as wrinkles, rhytids and scars. Beginning with the Baseline visit (Visit 1), subjects will receive a total of 3 treatments approximately 3-5 weeks apart. The left and right side of the face will be treated and assessed as independent sites, and the same applicator tip configuration will be used to treat both sides at all 3 treatment visits.
Acne Scar Improvement [ Time Frame: 6 and 12 Weeks Post-Final Treatment ]
Change in acne scarring at 6 weeks and 12 weeks post-intervention compared to baseline as assessed by blinded evaluators by photographic assessment utilizing a 7 point Global Aesthetic Improvement Scale (GAIS) for acne scarring.
Secondary Outcome Measures :
Subject Satisfaction [ Time Frame: 6 and 12 Weeks Post- Final Treatment ]
Subjects' assessment of satisfaction with the treatment using a 5 point Subject Satisfaction Scale at 6 weeks and 12 weeks post-treatment.
Subject Scale - Visual Analog Scale for Pain [ Time Frame: Up to 3 Months Post Enrollment ]
Subjects' assessment of discomfort and pain after treatments as measured by a 10 cm visual analog scale (VAS).
Incidence of Treatment-Related Adverse Events [ Time Frame: Up to 12 Weeks Post-Final Treatment ]
Subjects experiencing a treatment-related adverse event (AE) by 12 weeks post-treatment.
Subject Scale - 5 Point Scale for Treatment Tolerability [ Time Frame: Up to 3 Months Post Enrollment ]
Subjects' assessment of treatment tolerability as measured by a 5 point scale
