The Diode Cold Laser has unique and special characteristics. The number of flashes is unlimited, ranging from 2 to 3 million flashes. This means the device will last you a lifetime—you won't need to discard it when the flashes run out, unlike some other devices. The device head includes a cooling feature, which is optional. If activated, it can reach a temperature of 8 degrees Celsius. It helps cool skin irritation, prevents burns, and allows you to enjoy treatments without any stinging or discomfort. It comes with 3 lenses designed for use on the body, face, and sensitive areas. The device operates using electricity and automatic pressure. Laser usage is minimal—approximately one month of use with only one lens.
