Red light therapy
Red light therapy (RLT) is an ineffective kind of light therapy in which the skin of the patient is exposed to long-wavelength red light, near or including the infrared portion of the spectrum, during a series of sessions. There is no evidence that RLT is effective at treating the skin or any other part of the body for any medical condition.[1]
RLT is being promoted in the popular media with unproven claims of multiple benefits.[2]

Three reviews examined laser and light therapies, and found some evidence of superiority only for blue or blue/red light treatment over placebo light, but a general absence of comparisons against other acne treatments. Photodynamic therapy had consistent benefits over placebo but was associated with significant side-effects and was not shown to be better than topical adapalene.
