IPL Hair Removal Device is a personal, light-based, home-use hair reduction device intended to be sold over-the-counter. The device provides hair reduction by using Intense Pulsed Light (IPL) technology. It works below the skin's surface and does not involve any cutting or pulling, reducing hair growth with minimal pain. The device is only powered by the external power adapter (100-240V, 50/60Hz) and its IPL emission activation is by finger switch. It contains a skin sensor to detect appropriate skin contact; if the light outlet of the device is not in full contact with the skin, the device cannot emit the treatment light pulses. The device includes JP1, JR3, JR8, JR9 four models. There is difference in product appearance, physical product dimension, indicator display, spot size and output energy, but their intended use, performance, structure design and operation are basically identical.
