Q: Can I use the devices too much / for too long?
There is an upside down U shaped response curve when it comes to red light benefits More is not always better! The great thing about Mito Red Light devices is that you can reap the same benefits in less time versus other products on the market. 5-15 minutes a day is really all you will need.
Having said that, Red (620-700nm) and NIR (800-900nm) light is very safe and there are no known negative side effects after over 3,000 clinical studies.
