Skin Needling

this method also called needle dermabrasion, dry tattooing or tattooing without pigment.

It is a technique whereby a Dr. or Tattoo artist uses either a hand tool or a tattoo machine to “needle or “tattoo the skin without using pigment (water can be used in place of ink). This is said to "break up" the scar tissue thereby smoothing the appearance of the skin.
NOTE: It is possible to “needle yourself, but there are risks associated with this. Also, results are generally not as pleasing. It is best to see a specialist whenever possible.
