Red light therapy, also known as low-level laser therapy (LLLT) or photobiomodulation (PBM), is a non-invasive treatment that uses red or near-infrared light to stimulate cellular function and promote healing. The wavelengths of light used in red light therapy penetrate the skin and can reach the cells, where they may have various positive effects. This therapy is believed to enhance cellular energy production, improve blood flow, reduce inflammation, and accelerate tissue repair. It has been used for a variety of purposes, including promoting skin health, reducing pain and inflammation, and supporting muscle recovery. Red light therapy is applied using devices that emit specific wavelengths of light, and it is considered safe when used as directed.
