670 nm therapy
670 nm therapy uses red light at a specific wavelength (670 nanometers) to stimulate cells and tissues in the body. This form of low-level light therapy works by delivering light that cells can absorb, which can prompt biological responses without heat or damage. In particular, the light can help the tiny energy factories inside cells work more efficiently, reduce inflammation, and encourage repair processes. The treatment is noninvasive and is applied externally, often with LEDs or lasers, for short sessions over several days or weeks depending on the condition. Researchers and clinicians are studying it for a range of uses, from supporting skin healing to helping cells in the eye and brain. While many studies show promising results, outcomes can vary and more research is needed to pin down the best doses and schedules. It is generally considered safe when used properly, but people should follow professional guidance and avoid overuse. 670 nm therapy is not a cure-all, but it is a useful tool in the growing field of light-based treatments that aim to improve cellular health.
