3. Wrinkles
Principle:
The standard dermaroller used for acne scars is a drum-shaped roller studded with 192 fine microneedles in eight rows, 0.5-1.5 mm in length and 0.1 mm in diameter. The microneedles are synthesized by reactive ion etching techniques on silicon or medical-grade stainless steel. The instrument is presterilized by gamma irradiation. Medical dermarollers are for single use only.
THE PRINCIPLE-COLLAGEN INDUCTION THERAPY
The medical dermaroller needles are 0.5-1.5 mm in length. During treatment, the needles pierce the stratum corneum and create microconduits (holes) without damaging the epidermis. It has been shown that rolling with a dermaroller (192 needles, 200 µm length and 70 µm diameter) over an area for 15 times will result in approximately 250 holes/ cm2 . Microneedling leads to the release of growth factors which stimulate the formation of new collagen (natural collagen) and elastin in the papillary dermis. In addition, new capillaries are formed-this neovascularisation and neocollagenesis following treatment leads to reduction of scars.[4‐6] The procedure is therefore aptly called “percutaneous collagen induction therapy” and has also been used in the treatment of photoageing.
DERMAROLLER FOR ACNE SCARS-THE PROCEDURE
Microneedling is a simple office-based procedure. The area to be treated is anesthetized with topical anesthesia for 45 minutes to one hour. After preparation of the area, rolling is done 15-20 times in horizontal, vertical, and oblique directions; Petechiae or pin-point bleeding which occurs is easily controlled. After treatment, the area is wetted with saline pads. The entire procedure lasts for 15 to 20 minutes, depending on the extent of the area to be treated. A minimum of six weeks is recommended between two treatments as it takes that long for new natural collagen to form. Three to four treatments may be needed for moderate acne scars
