My husband has back pain and has been using the Celluma light therapy on it. He says it helps a little, I am happy it helps him. Because any relief for him is great. I have been using it on my knee and it does help me a lot. And I have also used it for wrinkles. I really haven't noticed anything there yet. But I was told in time you will. I want to thank you for your product, yes it is expensive but I really think in time it will pay off for us.
