I bought this out of curiosity. This is a tint device and it is operated on battery. It has vibrations which is mild enough to be used everyday. And the LED colour is Red which is good for anti-ageing. I use it after applying creams and it helps with the absorption of the cream into the skin. And i use it for a few minutes after which ky skin feels more firm. It could be a temporary effect, but I love it as a massager!
