DERMAROLLER
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.
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 studyTrusted 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

Many people use it to try to combat the signs of aging, such as:
• loss of skin firmness
• appearance of fine lines
• start of wrinkles
