Abstract
BACKGROUND: Fractional microneedle radiofrequency (FMRF) systems are popular options for treating acne scars. However, treatment efficacy when used in combination with traditional ablative fractional laser (AFL) and the safety profile with concomitant use of isotretinoin remain unknown.
OBJECTIVE: The aim of this study was to assess the safety and efficacy of an early intervention combination treatment protocol for inflammatory acne and acne scars.
MATERIALS AND METHODS: The electronic records of 71 patients with inflammatory acne and acne scars were included in this retrospective observational study. Data were collected for all patients who received combination FMRF and AFL. Within the study group, 43 patients were receiving low-dose isotretinoin or had completed isotretinoin within the past 3 weeks.
RESULTS: The mean Scar Global Assessment score significantly decreased after 3 sessions of combination treatment (n = 71). Patients with inflammatory acne showed a significant decrease in the number of inflammatory lesions (n = 30). Patients with concomitant low-dose isotretinoin use reported a further decrease in Scar Global Assessment score (n = 43). There were no reported persistent side effects, including prolonged inflammatory reaction or scarring.
CONCLUSION: Combination treatment with FMRF and AFL is an effective and well-tolerated treatment modality for acne scars and inflammatory acne.
