Light has been used for healing since ancient times, but in 2025, we are moving from "sunbathing" to precision science. Photomedicine uses specific wavelengths of light—lasers, LEDs, and infrared—to trigger chemical reactions in our cells that speed up healing, kill cancer, or even fix our vision.
Here is the latest on photomedicine, without the complex physics.
