Treatment of facial post-burn hyperpigmentation using micro-plasma radiofrequency technology

Management of facial post-burn hyperpigmentation is a common and challenging problem for dermatologists and plastic surgeons. The recent development of micro-plasma radiofrequency technology, which allows precise and rapid treatment with controlled thermal injury, can be an effective treatment of post-burn hyperpigmentation. This study aimed to evaluate the effectiveness and complications of micro-plasma radiofrequency treatment of post-burn hyperpigmentation. The study included 35 patients with Fitzpatrick skin type III or IV and facial post-burn hyperpigmentation. Patients received three to five treatments at 8-week intervals. A roller tip was used with the power setting at 60–90 W, and 3–4 passes were made in different directions. The degree of improvement and complications were recorded. Improvement of hyperpigmentation was evaluated by patient self-assessment and by plastic surgeons who compared digital photographs taken before treatment and 2 months after the last treatment. The results showed that post-burn hyperpigmentation responded favorably to micro-plasma radiofrequency treatment with very few complications. The average pain score using a visual analog scale from 0 to 10 was 6.7 ± 0.7. After a series of treatments, 32 of the 35 patients had achieved a >51 % improvement of their hyperpigmentation, and 3 patients had achieved a fair improvement. The mean score for improvement of hyperpigmentation was 4.28. Patient self-evaluations indicated good satisfaction with the cosmetic outcomes, and some softening of the scars. Micro-plasma radiofrequency technology is appropriate, effective, and safe for the treatment of facial post-burn hyperpigmentation, and provides a promising noninvasive treatment for superficial facial injuries.
