The efficacy of intense pulsed light and heat energy therapy compared to benzoyl peroxide gel 2.5% in the treatment of mild and moderate acne vulgaris

The use of technology-based light therapies such as intense pulsed light and heat energy(IPL) provides an alternative therapy for patients with acne. However, clinical evidenceis required to evaluate the efficacy and safety of the IPL. This study aimed to evaluate theefficacy of IPL compared to benzoyl peroxide (BP) as standard therapies in patients withacne vulgaris. The study was conducted with randomized controlled trial parallel designinvolving patients with mild and moderate acne vulgaris. Acne severity was determined bythe method of Combined Acne Severity Classification (CASC). Statistical analysis usingrepeated measurement analysis of variance was conducted to assess the reduction inlesions and number of P. acnes in each group followed by independent t-test to compareof both groups.
