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.
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.
