Successful treatment of facial atrophic acne scars by fractional radiofrequency microneedle in Vietnamese patients

Abstract

AIM: This study aimed to evaluate the effect of the fractional Radiofrequency microneedle treatment for facial atrophic acne scars. METHODS: A group of 52 patients were recruited for the study. Goodman & Baron’s acne scar grading system was used for assessment at their first visit and the end of 3 months after the last treatment session. RESULTS: The results displayed that 73.1% of patients have the improvement of the Goodman scar level after four times of treatment. The Goodman and Baron scar point mean was reduced from 16 ± 7.6 to 5.6 ± 5.0 (p < 0.01). Post-inflammatory hyperpigmentation was experienced in 5 patients (9.6%). CONCLUSION: The microneedle fractional Radiofrequency is an effective treatment method of facial atrophic acne scars, with minor side effects and a short downtime.
