Professional-grade devices utilizing light-emitting diodes (LEDs) within the red and near-infrared spectrum are employed in various settings, including wellness centers, athletic training facilities, and medical practices. These devices deliver specific wavelengths of light to the skin, purportedly stimulating cellular processes and offering potential therapeutic benefits. An example application involves exposing targeted areas of the body to red and near-infrared light for a prescribed duration.
The use of light for therapeutic purposes has a long history, dating back to ancient civilizations. Contemporary research suggests potential advantages in areas like skin rejuvenation, pain management, and wound healing. This burgeoning field continues to be the subject of ongoing investigation as scientists explore its mechanisms and efficacy. The availability of these devices in commercial settings offers wider access to this evolving modality.
