Abstract
Background/Objective: A variety of modalities are available for the treatment of acne scars. This prospective, IRB-approved study evaluates the efficacy and tolerance of fractional bipolar RF energy in the treatment of facial acne scars. Methods: Healthy subjects (n = 15, 13 females, aged 35.7 ± 5.6 years [mean ± SD], skin types I–V) with mild to moderate acne scars received three monthly treatments with a fractional bipolar RF device. Improvement and tolerance were evaluated at each visit, including a 1-month and 3-month follow-up visit. Results: Ten subjects completed the study. Physician-assessed acne scar severity was significantly reduced at 1 month and 3 months. Adverse effects were limited to transient erythema. Dryness, bruising and crusting erosion were limited. Subject-assessed stinging/burning, stinging (alone), tingling, itching and burning were also limited and consistent with each treatment. Subject-assessed fine lines and wrinkles, brightness, tightness, acne scar texture, pigmentation were all improved significantly. Satisfaction was high in 67–92% of subjects. Conclusion: Fractional bipolar RF energy is a safe and effective modality for the treatment of acne scars.
