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
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
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
Some people also use it to try to reduce pore size or reduce the production of an oil called sebum if their skin is oily. Others try dermarollers to try to improve the appearance of stretch marks
