Blue, red, and infrared light have been used medically for decades, so these therapies have been approved or cleared by the FDA. This is increasingly important because both red and blue light claim to have benefits that could technically be described as medical benefits - such as treating inflammation, muscle pain, and healing.
Other light therapies, such as green, red, violet, cyan, and yellow, while many studies have shown them to be effective in treating the skin conditions they claim to treat, have not been used in medical treatments to the same extent as red, blue, and infrared, and therefore have not been cleared or approved by the FDA to date. In fact, any LED device that treats colors beyond red and blue will not be approved by the FDA. However, all of our products have been tested by the European Union CE and have received the CE certificate, so they are independently certified for safety.
