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 20 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Subject Satisfaction | 12 Weeks Post-Final Treatment | Subjects' assessment of satisfaction with the treatment using a 5-point Subject Satisfaction Scale at 12 weeks post-treatment. The Subject Satisfaction Scale is a five-grade subjective test. Possible responses were (4) Very Satisfied, (3) Satisfied, (2) Having No Opinion, (1) Unsatisfied, and (0) Very Unsatisfied. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Treatment Pain | Average of all treatments | Subject's assessment of discomfort and pain assessed immediately after treatments as measured by a 10 cm visual analog scale (VAS). The Visual Analog Scale is a scale from 0 cm (no pain) and 10 cm (pain as bad as it can be). |
| Subject Scale - 5 Point Scale for Treatment Tolerability | Average of all treatments | Subject's assessment of treatment tolerability as measured by a 5 point scale. Participants were asked about their treatment tolerability level immediately post-treatment. Possible scores were; (4) Very Tolerable, (3) Tolerable, (2) Having No Opinion, (1) Intolerable, and (0) Very Intolerable. |
