Well, I have been using this with the eye attachment for 2 weeks, every day. I can't see any improvements on the skin so far but probablyit will take more time, the gel that came with made me break out, even if my skin is not sensitive, so I've stopped using it. The app that you HAVE to use if you want more "professional " treatments is so frustrating, lagging, the video will freeze but the treatment will go on and you can't hear or see anything, just the timer going. If you are kicked out mid treatment, you just need to retart it all over agin, you can't pick up from where you were kicked out...I had to login and register my device 3 times in 2 weeks because the app just kick me out and deleted my device from the account. Such a shame that I can't use it to his full potential.
