With the Medisana IPL 850 you will be assured of smooth legs in the coming years. This IPL device has 200,000 flashes of light. The more light flashes a device has, the longer you use it. 200,000 light flashes is approximately equivalent to a 15-year use. Thanks to the glide function, you can slide to the next piece of your skin without lifting the device. This means that you do not have to interrupt the flash every time and you're done faster. You set the desired light intensity yourself by selecting 1 of the 5 levels. The built-in sensor indicates when you use too high intensity for your skin type. This prevents damage to your skin and the IPL device.
