Below you will find a list of abstracts and studies discussing low level light therapy or light emitting diode (LED) light therapy. These abstracts and studies cover areas of acne and pain management with emphasis on the effects of LED light therapy for these conditions. Please take the time to review these materials and see the science behind LED light therapy.
