Review: love it? - easy to use and i can see a difference with my skin. :)
Review: Heals skin cuts quickly - I bought this device for the cold sore, but the cold sore hasn't come back yet. I have used the red light for a skin cut on my finger and tongue, and the blue light for a dark spot on my face. On pulse mode only. It's been a month. So far, it works wonders on skin/tongue cuts. The dark spots are not fading yet. I like the 5-minute auto shut-off. The two different tips are useful. It has a metal body and is well-built. Only one battery is included. Asked the seller questions and they responded quickly. I still can't figure out how and when to use the other waves. I sure hope the instructions will cover more. It would be nice if it came with a pair of protective glasses. I will keep updating my review and change the rating accordingly. I don't use this device for treating muscle/joint pain because I have a few massage guns that did wonders for me. Thanks to other reviewers who made it easier for me to decide which brand to purchase.
