Of course, I was skeptical of the effectiveness of photon therapy… but it exceeded my expectations! I have only been using the system for almost two weeks but I have noticed an immediate result. Two of my close friends each tried a single 15-minute treatment. Their skin has less redness and was tighter. The blue light seemed to calm down the skin as well as preventing additional redness from the other lights. The microcurrent also helps me much on the skin toning and my appearance. continues to improve the skin. Without a doubt, this was a great purchase.
