DERMAROLLING or MICRONEEDLING is a process that was originally carried out by a dermatologist.

A dermaroller is a skin care device. On one end is a handle and on the other is a roller with lots of small, fine needles on its surface.

As this 2009 review explains, dermarollers were invented through a series of discoveries. Two independent studies in the 1990s explored the use of needles to treat scar tissue. But it was not until 2005 that the first study reported the use of a dermaroller.

There are a number of different brands of dermaroller available, and they are considered to be relatively inexpensive.

It is important to purchase one from a trusted retailer and to make sure that it is sterile before it is used.
