Abstract
Background: RF‐pulsed light with ELOS technology devices have recently been used to treat acne vulgaris in selected patients. Objective: To investigate the safety and efficacy of a combination of two kinds of device with ELOS technology for the treatment of acne. Methods: Ten patients with moderate acne were treated twice weekly for 4 weeks with the Aurora AC® (Syneron Medical Ltd, Yokneam, Israel), a combination of pulsed light and RF energy. Immediately after Aurora AC treatment, all patients were treated weekly only on one facial half with the Matrix IR® (Syneron Medical Ltd), a combination of fractional diode laser and RF energy. Photographic documentations were obtained at baseline, before each treatment session, and 1 and 3 months after the final treatment. Results: At 3 months after treatment, the mean lesion count was reduced by 38% (p<0.05) after eight treatments with the Aurora AC alone. With additional treatment with the Matrix IR, the mean lesion count was reduced by 61%. Conclusion: The combination of Aurora AC and Matrix IR was superior in reducing the acne lesion count, and in extending the length of the remission period.
