I have had the LED mask from Dr Dennis Gross for a few years now and TBH I am really on the fence if it actually does anything lol. It is crazy expensive and the one i got was not a great design when it came to the head strap which broke after about a year (when you spend over $600 i expect it to last). I think they have improved the design since then but still, it's a lot of money and i'm not sure its worth it.
