Convenient form of light therapy
This device is a very convenient way to experience red light therapy  at home.  It works basically like a flashlight, just turn it on and aim it at the source of pain.  It is a mild heat that is supposed to penetrate deep into the muscles to sooth and help heal tightness or injury.<br />It also is supposed to help build collagen, thus fighting wrinkles.<br />All this takes time , so all I can really say at this time is that the heat feels good and the device is easy to use.
