Light-Based Devices for the Treatment of Facial Erythema and Telangiectasia.

Facial erythema is one of the most common outpatient complaints in dermatology. There are various causes of facial erythema and several devices are available for its treatment. Pulsed dye laser (PDL) and intense pulsed light (IPL) are the two common light devices used for these conditions. In this review, we evaluated the literature to assess efficacy of IPL versus PDL in facial erythema and telangiectasia. We searched published articles including clinical trials or reviews articles, case series, and case reports. Electronic databases (MEDLINE and PubMed) were searched to retrieve the articles. Reference lists of selected articles were also considered for the review. Articles published in English language until June 2021 were considered for this review.
