Study hypothesis
Acne patients are increasingly developing clinically significant antibiotic resistant propionbacterium acnes resulting in the reduced effect of antibiotic therapy. Therefore, there is a need to develop non-antibiotic treatment options. A small study has shown benefit from treatment with a short pulse width 0.35 msec low energy pulsed dye laser used as monotherapy. Due to the expense of this type of treatment, it is important to determine the value of pulsed dye laser treatment as adjuvant therapy in patients receiving conventional antibiotic therapy. Most pulsed dye lasers use a longer 1.5 msec pulse width and the effect of this type of laser as adjuvant therapy for acne also needs to be determined. Therefore the aim of this study is to assess the effect of both an N-lite low energy pulsed.
