A dermaroller is a skin care device used to help rejuvenate the skin, treat acne scarring, and reduce signs of aging. Dermarolling or micro needling 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. 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. Acne is a common skin problem that can affect both teenagers and adults. Having to deal with acne itself is bad enough, but acne can also leave behind permanent scars. Acne scarring can really have a negative impact on your self-esteem and quality of life.
