Ladies, I wanted to add to this post since I too have some experience with micro needling. I bought both a derma roller and a the derma pen. I have used it on and off mainly for my face and like the results. The one thing is that...
What is the name of the serum you are using? I have seen a lots of products sold online. On this site there seems to be mention of only two products - Procell (made from human bone marrow) and Bioipelle (made from snail "serum").
