This therapy is knownnto help skin and hair .
I just started the therapy but it is not hot...it has LEDs that do not emit heat. It is comfortable though I get conflicting info about covering my eyes, so I wear small blockers that just cover the eyes. It is too early to say what it does for ME, but I have read many positive information from medical studies. It doesn't hurt you and I do not use the light for long sessions. My skin seems to like it.
