4. I'd give the Dermaroller some more thought. It's cheaper, downtime is less, and the results are comparable to fractionated laser. I have to stress the importance of only being treated by a professional who uses the original medical-grade Dermaroller, with 192 needles at 1.5mm in length. Anything else is inferior and a complete waste of time and money. Dermaroller has given me my life back. 
remember there are different needle sizes for different levels of scarring. I would say 0.75mm derma roller should do the trick for you.
Thanks for the information about the tropical numbing cream. Quirky you suggested that anything less than 1.55mm derma roller is not going to be effective.
I'm prepared to deal with the extra pain if it means that the results would be guaranteed. Is there any increase risk with the 1.55mm as oppose to the 0.75mm?

No pain! Trust me when I say that the Fraxel laser I had made me convulse on the table... it really did. Even with heavy numbing cream I still felt every pass of the laser. Compare this to the Dermaroller and I could have the treatment all day without complaining.
Everyone has a different threshold for pain. Coneill, I have had 4 professional Dermaroller treatments and I actually look forward to going
again. They ease you into it by making each treatment that little bit more "aggressive" (not a good word but it's close). Your face is thoroughly cleaned and numbed before the treatment, it's a cake-walk! 0.75mm? Pfft, you might as well spend the money at the pub because it would be a waste spending it on a roller with needles that length.
You need the 1.5mm, this is science. Human skin has an average thickness of 1.5 mm so why would you opt for shorter needles when treating scars? Anything less will not reach the depths in your skin required to maximise improvement. Anything longer and it's actually detrimental to your skin! They only use longer needles on burn victims.Again, I can't stress the importance of finding someone who is trained for and uses only the
original Dermaroller. It's easy to check. Just a few questions and you'll be on the right track:
1. Is it a medical-grade, single use device?
Nothing plastic! The Dermaroller is medical-grade steel. Think of this as an operation. Would you want a surgeon using a plastic knife to cut you open? Yes, the needles are not plastic but the point is about durability and sterility!2. Does it have 192 needles at 1.5mm?
If the device has any more than this then move on, move on! Too many needles will actually rip up your skin (in loose terms) and will cause unnecessary trauma which could lead to further scarring or other problems.www.dermaroller.de <-- It's in German but there is a little English flag you can click to translate their site. Maybe read up about the actual science behind the device and understand why you need 192 needles at 1.5mm and why you must wait 6-8 weeks between treatments.

I'm not affiliated with the Dermaroller, so don't think I'm just plugging them. I am an avid believer in their products after having my four treatments. The original Dermaroller is the only device that is
TGA listed (if they use words like "approved", or "acknowledged" it means that their device is a crappy, cheap copy). I think the term is FDA in the States? It needs to be
listed as every medical device in their database has gone through strict testing and has been thoroughly scrutinised. It is then, and only then, that the device can be listed as safe. Companies that claim that their device has been "approved" by the TGA (FDA) have
not had their device tested and you will not find their device in the TGA/FDA database. Instead, they consider it okay to market and use a device that is
similar to the Dermaroller because heck, our device looks similar so it must be fine yeah? Wrong! The term Dermaroller is used widely and inappropriately to describe other devices by other companies. Why there have been no law suits against copyright infringement is beyond me! Always look for mention of the name
Horst Liebl. 
So, don't try to treat yourself at home, get a professional who uses the original Dermaroller, add in some patience and a good skin care regime and I think you'd see awesome results! Keep in mind that you'll likely need 5 treatments spaced 6-8 weeks apart though.

Don't put your skin in jeopardy by choosing an inferior device/technician. Yes, the other companies are cheaper, but this is because their devices are easier to make (plastic, inferior needles etc).
As for risks, no long-term, serious side effects or negative outcomes have ever been reported from patients who have been treated with the original German-made Dermaroller. The same cannot be said for other rollers... I've read lots of horror stories. The esthetician who treats me has also been trying to correct damage to the skin of some of her clients who have tried cheap rollers. She said they mostly look like they have enlarged pores or "cat-scratch" like lines on their faces. For privacy reasons I haven't seen pictures but I can imagine what they must look like. My esthetician also has Dermaroller treatments performed on her face (by another trained professional) so I know that she's not just in it for the money, she has also been seeing positive results in her skin.

I'm sorry for the spiel. I get quite heated when talking about this because all the misinformation that's out there makes me angry. All I can say is do your research!
