I’d say so far so good! Been using it for about 11 days now. I have read it takes about 8-12 weeks to really start seeing the bigger effects of the red light therapy. I started out at 10 minutes a day for the first 2 days, then went to 15 for one day, and then up it to 20 minutes every day after. I actually did 20 yesterday for front, and 20 more for back later in the day. I’ve been having terrible lower back pain the last two days. Woke up this morning with back feeling much better. I do believe my belly fat is less and my skin on my face feels very soft, and pores on the chin appear to be smaller. A couple of my goals is to see face tightening and to help with carpal tunnel in my thumbs, among a few other goals. I know it’s helping internally and those results will eventually come. As in everything in life you need to believe in what you are doing…. As the power of the mind is bigger than we can imagine! So to finish up I’d say I’m very satisfied so far. While using the lights I feel warmth which is very relaxing, and in my lower back where it hurts I have tingling that is going on. so I know something is happening there. I will be excited to do another review in a few weeks!
