The Dermaroller, How It Works and Its Benefits

Microneedling with dermaroller is a new technique that treats scars, stretch marks and wrinkles, and for overall facial rejuvenation. It is a trouble-free and fairly cheap modality that is also used for transdermal administration of drugs.

Background

Dermaroller first became popular as a simple way of treating scars, specifically acne scars. It may be used safely by any licensed dermatologist with minimum training.

The Dermarolling Instrument

The typical dermaroller used for acne scars is drum-shaped and studded with 192 microneedles – 0,1 mm in diameter and 0.5 to 1.5 mm in length – arranged in eight rows. The microneedles are etched into silicon or medical-grade stainless steel with the use of reactive ion techniques. Gamma irradiation is used to pre-sterilize the instrument. Medical dermarollers may only be used once.

How It Works

The length of each medical dermaroller needle is 0.5-1.5 mm. During treatment, the needles prick into the stratum corneum of the skin and create holes known as microconduits, without damaging the epidermis. Dermarolling over a particular area 15 times makes about 250 holes for every square centimeter. Microneedling spurs the release of growth factors that stimulate new collagen (natural collagen) and elastin formation in the topmost layer of the skin called the papillary dermis. Additionally, new capillaries are formed, and with this post-treatment neovascularisation and neocollagenesis comes a visible reduction of scar tissue. Thus, the procedure is fittingly called “percutaneous collagen induction therapy,” and has been used in photoageing treatments as well.

Dermarolling and Acne Scars

Microneedling or dermarolling is fast and simple procedure that can be done in any office. The treatment area is first anesthetized using topical anesthesia for 45 to 60 minutes. When the area has been readied, the dermatologist begins dermarolling, making 15 to 20 vertical, horizontal and oblique, horizontal and diagonal strokes. The site is then wetted using saline pads. The whole procedure runs for 15 to 20 minutes, depending on the size of the treatment area.

Prior to the next treatment, there should be at least a six-week gap, the period it takes the body to manufacture new natural collagen. Moderate acne scars will probably require three to four treatments.

After Care

In general, microneedling is well-tolerated by patients, although it can cause erythema, which may last for a maximum of three days following treatment. Photoprotection for one week is recommended and application of local antibiotic creams may be necessary. Patients are normally able to return to work the following day.

Self-use Dermarollers

Home-use dermarollers are often shorter than 0.15 mm in length, and are very useful for the transdermal delivery of lipopeptides and many other anti-aging substances. Most brands may be used twice weekly for up to a hundred times. After every use, the rollers must be cleaned with hot tap water and shaken dry.
