Abstract

Light-based acne treatments may represent a new emerging treatment for acne that does not increase the risk of bacterial resistance and they may be potentially effective with a favorable safety profile. Current data show that photodynamic therapy reduces inflammatory lesions and significantly improves acne. However, there is no consensus on the optimal implementation in the treatment of acne. In addition to topically applied photodynamic therapy, intense pulsed light, pulsed dye lasers, potassium-titanyl-phosphate lasers, infrared diode lasers, broad-spectrum continuous-wave light sources (red light, blue-red light) have been introduced as alternative treatments. Since well-designed studies to evaluate their efficacy versus traditional medical therapies are lacking and standardized regimens have not been agreed upon, procedures including laser, intense pulsed light, and photodynamic therapy should currently not be considered first-line treatment for inflammatory acne.

Keywords: Intense pulsed light therapy; Lasers, dye; Lasers, solid-state; Photodynamic therapy; Photosensitizing agents.
