Abstract

OBJECTIVE: To explore the efficacy of facial acne scars treatment with micro-plasma radio frequency. METHODS: A total of 24 patients with facial acne scars underwent micro-plasma treatment for 3 - 5 times. And their efficacies were evaluated by the patient photographs before and 2 months after treatment. RESULTS: Facial acne scars were characterized by clouds of pitted scars with no specific shape. No difference appears in susceptibility between males and females. The overall improvement rate was 83.33%. The degree of improvement was as follows: significant 33.33%, moderate 25%, mild 25% and poor 16.67%. CONCLUSION: Micro-plasma technique is an effective therapy for acne scar.
