How do dermarollers work?
Dermarolling or microneedling is a process that was originally carried out by a dermatologist. It has gained popularity in recent years as an accessible, effective, and relatively non-invasive skin treatment.We are happy to explain how derma rollers work and offer tips for getting the best results.
A dermaroller is a skincare device used to help rejuvenate the skin, treat acne scarring, and reduce signs of ageing. But how does dermarolling work?
What is a dermaroller?A dermaroller is a skincare device. On one end is a handle and on the other is a roller with lots of small, fine needles on its surface.As this 2009 reviewTrusted Source explains, dermarollers were invented through a series of discoveries. Two independent studies in the 1990s explored the use of needles to treat scar tissue. But it was not until 2005 that the first study trusted Source reported the use of a dermaroller.
How it worksWhen 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.As this 2016 study trusted Source of the technique explains, 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
Uses of a dermarollerDermarolling was originally used by dermatologists as a way of boosting collagen production for treating facial scars and skin rejuvenation.It is now also used as a way to deliver therapeutic drugs and vaccines through the skin.In addition, it improves the appearance of the skin. Many people use it to try to combat the signs of aging, such as:
- loss of skin firmness
- the appearance of fine lines
- start of wrinkles
People should avoid a dermaroller if they have a history of blood-clotting problems, or are using Accutane or other medical treatments.Dermarollers should not be used on areas of skin that have eczema, sunburn, or cold sores. Anywhere there are moles, skin inflammation, or rosacea should also be avoided.
