Lasers cause controlled damage to the skin to trigger an inflammatory reaction to promote wrinkle reduction and reduced redness. Ilyas says it’s helpful to compare how red light therapy works versus traditional skin devices, such as lasers and intense pulsed light (IPL). To further explain the effectiveness, Dr. a Pennsylvania-based board-certified dermatologist with Schweiger Dermatology. Red light therapy and other low-level light modalities take advantage of a phenomenon called photobiomodulation, which is how different components of our cells are activated or respond to different wavelengths of light, explains Erum Ilyas, M.D. “Think of it as your morning coffee-red light therapy helps your cells wake up and get the job done!” says Dr. With this boost to the energy center of the cell, the cells can do their jobs-such as healing and growth-more efficiently. Red light therapy works by activating your mitochondria, or the powerhouse of the cell, explains Dr. “Essentially, the red light stimulates your cells to work at a higher level.” How Does Red Light Therapy Work? “With red light therapy, you expose an area of your body to a specific wavelength of red light emitted by a device that can range in size from handheld to whole-body,” says Casey Kelley, M.D., founder and medical director of Case Integrative Health. Visible light penetrates biological tissues, such as cells, muscle tissues and nerve tissues-with red and near-infrared (NIR) light going deeper than green, blue or violet light. ![]() These studies led to the discovery that red light therapy could be used deliberately as a type of photomedicine, which is the application of light for health and healing purposes. “Nothing heals in space, so NASA funded many years of research with these lights for human trials.” Eells, Ph.D., a professor in the Department of Biomedical Sciences at the University of Wisconsin-Milwaukee. “It was here that astronauts tending the plant growth chambers noticed little scratches on their hands began to heal,” says red light therapy researcher Janis T. Microgravity Laboratory Spacelab mission (STS-73, Columbia) as part of experiments in plant growth. In October 1995, sources of red light-part of the visible spectrum of light-made their space shuttle flight debut on the second U.S. When it comes to the discovery of potential benefits of red light therapy, you can actually thank voyages to outer space.
