For effective hair removal you only need to glide the Magic Crystal in circles over the skin, using minimal pressure.
As a measure of how little you need to press, Magic Crystal only needs sufficient pressure to move the hair under the surface without any movement of the underlying skin. This is one of the fundamental features of using Magic Crystal; only use enough pressure to move the hair without any disturbance of the skin.
For most skin, getting the right balance of pressure is both easy and intuitive. However, where the skin is sensitive or delicate, achieving this balance can take experience and care. Unless you have considerable practice using Magic Crystal, we recommend that you avoid using it on the face, on your armpits and on the more tender parts beneath the bikini line.
