Be sure to clean a designated surface to place the things you'll need during the process. 2 Apply a thin layer of topicaine numbing gel to the treatment area. This step is only necessary for a deep, intense treatment; therefore it only needs to be done once a week. Wipe off any excess gel with a paper towel. 3 Roll the derma roller in different directions on the skin---four rolls vertically, horizontally and both diagonals should be sufficient enough to ensure desired results and stimulate collagen formation in the skin. Do not press too hard, but apply a significant amount of pressure. If you use your derma roller without the topicaine gel, less pressure should be applied. 4 Cleansing after treatment is an important step.
