The Silk’n ReVit Prestige removes dead skin cells that are sucked into the device using vacuum stimulation. These dead skin cells are captured by a filter that you can replace. When you change the filter, you will see how many dirt particles have accumulated on your skin over time. The real proof of the treatment of your skin is visible when you look in the mirror. Your skin has been balanced, the complexion is more even, and your skin appears visibly smoother and younger.
