Just wanted to share a guide that I found. Different depths are recommended for different parts of the face (this applies to Dermapens, Dermarollers, and Dermastamps). See the image on this link, as well as the charts hyperlinked to the page: http://www.dermapenworld.com/training/protocols/dermapen-treatment.html
Also, I've read that it takes about 4-6 weeks for the derma-needled treated skin to fully go through the healing process. So that is why it is recommended to space out the treatments to a certain area by that much time. I do not know what the long term effect will be (if any) of interrupting the healing process constantly. But, to get the maximum benefits, it is best to spread out the treatments.
PS--Don't know why they have listed the anesthetic. Lots of people use it but many say you don't need it. From what I have seen, it varies from person to person if they "need" it for bearing the pain, but it really isn't necessary.
