Light-based therapies have been successfully used to treat dermatological conditions since the early 1900's, with various parts of the electromagnetic spectrum (i.e. UV, visible, near-Infrared, etc.) demonstrating different benefits. Light-emitting diodes (LEDs) offer delivery of light to the skin in a gentler manner as compared to light delivered by lasers primarily due to the lower energy output. It has been reported that LEDs do not deliver enough power to damage tissues and do not have the same risk of accidental eye damage that lasers do. Visible-LED light therapy has been deemed a non-significant risk by the Food and Drug Administration and has been approved for use in humans.
