LED light therapy: the evidence behind the efficacy

Abstract

The plethora of modalities available to improve skin health and appearance is greater than ever, with one of these options being LED light therapy. Various LED-based devices for dermatological and cosmetic usage have become widely available, but the average consumer or aesthetic practitioner may not be confident in their efficacy or safety. Francesca Ramadan summarises the latest evidence-based applications of LED phototherapy and the research supporting its benefit to the aesthetic practitioner's toolkit.
