I’m a fan of red light therapy and have had a number of devices. Some were inconvenient, one face mask was so bulky as to leave marks, some weren’t user friendly and on and on. This device is easy to use and not cumbersome at all. Well crafted. Holds a charge for at least 3-4 uses. Does it work? Well, to be honest, no one has gushed about my beautiful skin - yet. But I’m 70 and notice that after a month, my skin seems to be brighter and looks fresher. I’ll take it. It works as well or better than the other devices I’ve had. The key is regular use and the crafting of this device makes regular use easier.
