Pleasantly surprised. The instructions are in English, but the device is easy to understand: press the on/off button for 3 seconds to turn it on/off. When the mask is turned on, press once to change the color; the last mode before returning to red alternates through all colors. I tested the red light, I believe the program lasts about 15 minutes. It heats up very little, no risk of burns. The mask is a bit uncomfortable and I find that the eyes are not well insulated, but I will do the sessions in relaxation mode with my eyes closed.

Good buy

So far so good. Arrived exactly as described. It does have 7 different lights; red, blue, green, purple, turquoise, white, and yellow. I'm using serums and face creams along with it so i can't review on whether it does something specific or not (like remove fine lines and wrinkles). The straps are adjustable to fit any size. I'm satisfied.

Very fast ! !! I like this device!

The face and neck lights are very easy to put on and use
