Derma-needling has been clinically proven to induce collagen synthesis.
It takes 1.5mm length needle for best results, at that depth utmost care for sterility of needles and skin are important.
High supplementation of Vitamin C (ascorbate) is necessary to support the collagen synthesis.
There is also a laser based treatment that heats the collagen under the skin causing it to contract and also induce collagen synthesis.
There is also threading -- which causes collagen synthesis google "thread lift"
All these processes induce collagen synthesis due to micro injury of the collagen layer.
Also google "jack lalane facial exercises" - you can find on youtube
Most of these treatments take months (6-10 or more) to show results.
Newer research from Dr. Lance Setterfield has shown that Dermarollers 0.5mm induce collagen. He has shown that even cosmetic rolls of 0.3mm can produce collagen via a different pathway than medical rolls.

Can you post a link to the research papers -- I would much rather use .3 or .5 ; .3 you really don't even need the numbing gel.
Yes that is a huge advantage to shorter needles. I remember rolling with a 2.0mm and it still hurt pretty bad with the numbing cream.
For most of the time I have rolled (3+ years) I have followed the advice of Sarah at owndoc.com who was basically following the advice of Dr. Fernandez.
With a 0.5mm you should not need numbing cream either. Dr.Setterfield say's that for best results you should incorporate both cosmetic and medical rolls into your routine. I personally don't care about product penetration. I'm interested in what the rollers themselves are doing.
I use a 0.75mm roller for medical rolls simply because I figure I'm a guy and our skin is a little thicker so just makes sense to me. Thinking outside the box if you will. I try to do cosmetic rolls every other night. Medical rolls once every 4 weeks.
