Anyone?

I would say single needle, especially if your skin between the scars is reasonably smooth.

In my experience my skin became ripply from rolling. It was much smoother prior.

It did help my scars- but didn't help the skin texture in general.

What would be a good place to purchase one online? Own docs.com has some but I'm not sure if they're any good

I just went to ebay looked at the mid price range and looked at reviews.

what did you search? Tattoo needles or?
