• Background Microplasma fractional radiofrequency (MP FRF) technology has been increasingly used for acne scars. Nevertheless, little evidence has analyzed the factors influencing its effectiveness before and during treatment. Aims To evaluate the clinical factors affecting the effectiveness of MP FRF therapy for atrophic acne scars. Methods We analyzed retrospectively the clinical data of 79 acne scar patients treated with MP FRF technology. The outcome of interest included the effectiveness and adverse events after MP FRF treatment. Multivariable logistic regression was utilized to evaluate clinical factors associated with effectiveness after the initial session. Results All patients received 115 sessions of MP FRF therapy (average: 1.5 sessions). Twenty‐eight (35.4%) patients improved moderately to excellently after one session. We found that the severe grade before treatment was negatively correlated with the effectiveness according to Goodman–Baron qualitative scores (OR = 0.02, 95% CI [0.001, 0.37], p = 0.009). The presence of icepick scars was also a negative correlation factor for the effectiveness (OR = 0.06, 95% CI [0.004, 1.00], p = 0.049). Furthermore, after excluding the effects of icepick scars and Goodman–Baron scores before treatment, ECCA scores were also correlated with effectiveness (OR = 1.04, 95% CI [1.01, 1.06], p = 0.009). Conclusion MP FRF therapy was effective in treating atrophic acne scars with no permanent adverse events. The severity of Goodman–Baron qualitative scores and icepick scars were independent clinical factors affecting effectiveness, suggesting the possible requirement for additional treatments other than MP FRF for severe acne scars and icepick scars.
