IPL Hair Removal Device is an over-the-counter, home-use device for unwanted hair removal by using Intense Pulsed Light (IPL). It has been designed in eight models with the same IPL technology for hair removal: KA-10, KA-11, KA-11C, KA-11D, KA-18, KA-20, KA-21, KA-21C. The device works below the skin's surface and does not involve any cutting or pulling, removing hair growth with minimal pain. The device is powered by an external power adapter and its IPL emission activation is by finger switch or auto flash mode. The IPL Hair Removal Device has an irreplaceable flash window and can cover an area of 3.0cm2 for models KA-10, KA-11, KA-11C, KA-11D, and 3.3cm2 for models KA-18, KA-20, KA-21, KA-21C, suitable for multiple hair removal areas such as upper lip, armpit, bikini line, arms, legs, etc. The device contains a skin sensor to detect appropriate skin contact; if the flash window is not in full contact with the skin, the device cannot emit the treatment light pulses. Additionally, the IPL Hair Removal Device has a sapphire cooling function (Model: KA-18, KA-20, KA-21) and ice cooling function (Model: KA-10, KA-11, KA-11C, KA-11D), activated throughout the hair removal process to cool down the treatment area's temperature and provide a better user experience.
