A split-face comparative trial of photopneumatic therapy versus intense pulsed light for the treatment of acne vulgaris.

Abstract

A novel photopneumatic (PPX) technology, combining blue light-emitting diode (LED) and broadband intense pulsed light (IPL) with vacuum pressure, was developed for the treatment of acne vulgaris (AV). In this study, we enrolled 50 patients with mild to moderate AV. Five successive treatments were performed on one side of the face with a combined PPX device, and the opposite side was treated with only IPL with the same fluences at 2-week intervals. Clinical improvement was evaluated by inflammatory and non-inflammatory acne lesion counts. Additionally, patient self-assessment scores were assessed. The results showed that inflammatory and non-inflammatory acne lesion counts were significantly improved on both sides of the face after treatment (p < .001, p = .001, respectively). Both inflammatory and non-inflammatory lesion counts were significantly reduced on the side treated with PPX when compared to the side treated with IPL alone (p = .008, p = .045, respectively). Thirty-eight of 44 patients reported slight to moderate improvement on the patient self-assessment score. No significant side effect was observed during the study periods.In conclusion, PPX therapy is an effective and safe modality to treat mild to moderate AV. This study shows that PPX therapy has superior efficacy for the treatment of AV compared to IPL monotherapy.
