Select a suitable skin area, such as your forehead, cheek, nose or upper lip, and roll systematically with the Dermaroller8 about 4-6 times vertically, horizontally and diagonally. Apply smooth, gentle pressure. Treatment should not feel painful but more like gentle pins and needles. There should be no other effects apart from a slight redness of the skin. You can roll as close to your eyes and lips as you like, but be careful as your skin is thinner and more sensitive in these areas. The treatment may also be used successfully on your neck, chest, the back of your hands, etc.
