Microneedling how often

To the question ”how often should microneedling treatment be done” one find different answers. In the table below, I have gathered up the recommendations from different kinds of sources.
From this information, a clear rule takes shape: the longer needles, the longer paus between treatments.

Needles longer than 0,5 mm are not recommended for home use.

It is interesting, that Dr Des Fernandes, who is worldwide known as "the father of microneedling", recommends rolling once a week.
For many years I have rolled 1-2 times a week myself, and with excellent results. Still, I don't want to claim this being the only and final truth. In this case (as in many other matters as well) I strive to get a view which on one hand is based on objective, scientic facts, and on the other hand I trust my own common sense and listen to my own body. I try, test and follow up very precisely, and I finish my own routines to get the optimal results. 

I read, that also Des Fernandes "self-tests all his products". I have a feeling, that I could have a lot to talk about with this gentleman 😊
