A Pilot Comparative Study of Alternating Blue and Red Light LED Phototherapy and Pulsed-dye Laser Therapy for Acne Vulgaris Treatment / 대한피부과학회지

ABSTRACT

Background@#Light-based and laser therapy have emerged as alternative therapies for the treatment of acne. Blue and red light-emitting diode (LED) phototherapy and pulsed dye laser (PDL) therapy are recognized as effective modalities in the treatment of acne vulgaris. @*Objective@#To compare the efficacy of LED phototherapy and PDL therapy in the treatment of acne. @*Methods@#We randomly allocated a total of 11 patients to receive LED combination therapy or PDL monotherapy.Outcome assessments included the number of inflammatory and non-inflammatory lesions, investigator’s and subject’s assessment, MexameterTM and CorneometerTM measurements. @*Results@#Five men and six women were enrolled in the study. After treatment, a greater improvement in the inflammatory and non-inflammatory lesions was recorded in the LED treatment group. Erythema score decreased more in the PDL treatment group than in the LED treatment group. Patient’s self-satisfaction was better in the LED treatment group than in the PDL treatment group. @*Conclusion@#This study suggests that both combination LED phototherapy and PDL monotherapy could be effective in the treatment of acne. Additional large-scale studies should be conducted to compare the efficacy of these two treatments.
