Review title is A simple and effective addition to skin care [SEP] The Wonderskin Derma roller seemed to be a prefect choice to see if micro needling was something I could incorporate into my facial routine. The unit itself came nicely packaged in it's own storage case which keeps it safe and clean when not in use. Instructions are printed on the box and suggest replacing the unit every 1 to 2 months.<br />I use the roller after washing and drying my face and before applying my facial cream. It doesn't hurt to use the roller but you do feel a prickly sensation. I'm hoping that the facial products I use are being better absorbed with use of the Wonderskin Derma Roller. I do notice a nice glow to my skin after using. I'm excited to see more improvement to my skin with continued use.
