A dermaroller is a skin care 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.
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.
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.
• 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.
