Successful removal of freckles with the bipolar radiofrequency and optical energy

Abstract

Objectives: Freckles are melanocytic lesions frequently seen on the face with red or blond hair. We aim to determine the effectiveness of combined bipolar radiofrequency (RF) and optical energy. Methods: Thirty patients with facial freckles received four treatment at 3-week intervals with RF and optical energy, combination of broadband light (580–980 nm) + bipolar RF energy 100 J/cm3. The improvement of the freckles was evaluated using the Freckles Area and Severity Index (FASI), and physician and patient assessment at the end of the sessions, at Months 3 and 12 after the treatment. Results: By the end of the study, assessment of results by physician for 83% at Week 12 and by patients for 70% at Week 52 was excellent or good. On the other hand, 88% at Week 12 and 76% at Week 52 of the patients reported that they were extremely or very satisfied. FASI was noted to be 65.15 at pre-treatment, 25.60 at 12th week, and 27.40 at the end of the follow-up (one year). Mean improvement rate (n = 30), as determined from the difference in mean FASI score, was 70% at 3 months and 66% at 12 months. Conclusion: Bipolar radiofrequency and optical energy can be accepted as an alternative treatment modality for the therapy of freckles with few adverse effects and high satisfaction levels.
