Evaluation of combined fractional radiofrequency and fractional laser treatment for acne scars in Asians

Background and Objectives Fractionated radiofrequency (RF) induces deep dermal heating and leaves the epidermis less affected. We studied the efficacy and safety of bipolar RF and fractional diode laser followed by fractional RF in Asians with acne scars. Materials and Methods Twenty‐four patients (skin types III and IV) with acne scars received up to five treatments of combined fractional 915‐nm laser and bipolar RF using a Matrix IR applicator (Syneron Medical Ltd, Yokneam, Israel) with fluence ranging from 50 to 70 J/cm2, RF at 70–100 J/cm3, double passes followed by full‐face bipolar fractional RF treatment using Matrix RF at energy ranging from 50 to 62 mJ/pin, at 4‐week intervals. Changes in acne scars, skin texture, pore size, pigmentation irregularity, and complications were assessed up to 3 months post‐treatment by standardized photographs obtained with Canfield Visia‐CR system®. Subjective improvement and patient satisfaction were assessed by questionnaire. Results Twenty patients (age 27.7 ± 8.4 years) completed the study. Modest but statistically significant improvement was noted in acne scars, with the mean grade decreased by 29% (P
