A dermaroller is a skincare device used to help rejuvenate the skin, treat acne scarring, and reduce signs of aging. But how does dermarolling work?
Dermarolling or microneedling is a process that was originally carried out by a dermatologist. Nowadays, it is also commonly done at home with little training. It has gained popularity in recent years as an accessible, effective, and relatively non-invasive skin treatment.
This article explores how dermarollers work and how to use one. It also offers tips for getting the best results.
What is a dermaroller?
A dermaroller is a skincare 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 trusted Source 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 trusted Source 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.
How it works
When the dermaroller is rolled over the skin, the small, fine needles on the roller puncture the skin.
The holes that the needles create in the skin are tiny and considered to be superficial. For this reason, the treatment is not seen as invasive.
When the skin is punctured, this creates a controlled skin injury. It does not cause actual damage to the outer layer of skin. The needles help to break down any scar tissue.
As this 2016 study trusted Source of the technique explains, the controlled injuries to the skin lead to superficial bleeding. This triggers the body’s wound healing response, and the following occurs:
- the skin releases substances that stimulate growth
- new blood vessels form in the skin
- the skin starts to make more collagen
Over the next 5 days, the collagen produced by the body is deposited in the area of treated skin. This helps the skin to become firmer and may reduce the appearance of fine wrinkles.
Research has found that skin treated with four microneedling sessions, 1 month apart, could lead to a 400 percent trusted Source increase in collagen.
