Danish doctor Niels Ryberg Finsen receives the Nobel Prize for Medicine for discovering the effects of light in the treatment of certain illnesses.
Scientists from NASA discover that red light creates a positive effect on the circadian rhythm of astronauts, particularly during sleep.
Russian professor and researcher Tiina Karu demonstrates that our cells have the capacity to convert red light emitted by LEDs into energy and to use this energy to its full potential.
Dr. Michèle Pelletier founds the Led Academy, a non-profit association that unites experts (physicians, physicists, researchers, engineers) interested in the biological effects and therapeutic use of low-power electromagnetic radiation sources.
Based on a meta-analysis of 33 clinical studies published around the world, Professor René-Jean Bensadoun proves the positive effect of LEDs on inflammation, tolerance, pain, scarring and duration of healing in the treatment of certain skin conditions.
Frenchmen Jérôme Grange et Jean-Marc Moncorger, PhD, form a scientific committee made up of dermatologists (Dr. M. Pelletier), neuroscience researchers (Dr. C. Gronfier) and physicists (O. Caselles), among others. Together, they create Helight™ to bolster global access to the esthetic and soothing benefits of red light.
