Background: Photobiomodulation is a process by which the absorption of red light energy produces a series of physiological effects at the cellular level such as the enhancement of mitochondrial Adenosine Triphosphate (ATP) production, cell signaling and growth factor synthesis, and the reduction of oxidative stress. Light emitting diodes (LEDs) photobiomodulation is an increasingly popular therapy for treating skin problems, especially for reversing the signs of skin aging.
Objective: The objective of this study is to demonstrate the effectiveness of a photobiomodulation treatment using red LEDs on the facial skin at a rate of two sessions per week for 3 months.
Background: The purpose of this study was to elucidate why some potentially damaging and beneficial effects were obtained following blue light exposures on skin.
Materials And Methods: Light-emitting diode (LED) devices containing 415 and 470 nm bulbs were used on normal human keratinocytes, skin biopsies and subjects with acne. Reactive oxygen species (ROS) evaluation was performed after a course of blue LED light exposures.
