Brief summary

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.

Interventions

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.

History of diseases stimulated by heat, such as recurrent herpes simplex in the treatment area; may be enrolled only after a prophylactic regime has been followed for 2 weeks or longer prior to enrollment, or according to Investigator's discretion. 10. Poorly controlled endocrine disorders, such as diabetes. 11. Any active condition in the treatment area, such as sores, psoriasis, eczema, and rash. 12. History of skin disorders, such as keloids, abnormal wound healing, as well as very dry and fragile skin. 13. History of bleeding coagulopathies, or use of anticoagulants (excluding daily aspirin). 14. Facial dermabrasion, facial resurfacing, or deep chemical peeling within the last three months, if face is treated. 15. Use of isotretinoin (Accutane®) or other systemic retinoids within six months or topical retinoids within three months prior to treatment; or as per physician's discretion. 16.

Subject Scale - Visual Analog Scale for PainImmediately post-treatment at each treatment (average of all 3 treatments)Subjects' assessment of discomfort and pain after treatments as measured by a 10 cm visual analog scale (VAS) with 0 being no pain and 10 being pain as bad as it can be. Each subject was asked to rate their pain after each of the 3 treatments. The result is the mean of each subject's mean VAS score.
Treatment TolerabilityImmediately post-treatment at each treatment (mean of the tolerability scores following each of the 3 treatments)Subjects' assessment of treatment tolerability as measured by a 5-point scale ranging from 0 (Very Intolerable) to 4 (Very Tolerable).
