A dermaroller is a skin care device used to help rejuvenate the skin, treat acne scarring, and reduce signs of aging. The dermaroller is a skin roller with several hundred micro-needles (540 for the face and 1080 for the body) whose diameter varies from 0.5 to 1.5 mm.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. This is the 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 top layer of the skin. The needles help to break down any scar tissue and also allows gentle exfoliation of the skin. It is used to fight against cellulite, reduce stretch marks and to reduce acne scars.


The size of the needle is the criterion of choice of a dermaroller. Here is a table that summarizes the use of the dermaroller.
