I have been using RubyLux Near Infrared bulb for some time now on my face and on legs for cellulite. I have started to see a difference after 2-3 weeks. I have fine lines around my lips, from smiling too much, lol. They are definitely less visible. Also my legs look smoother. I have been using it for 3 months a few times a week. It is much cheaper than a sallon solution and I can do it when kids are napping, which is awesome.
