One hundred twenty consecutive patients (skin phototypes I through VI) with facial and nonfacial scars from a variety of etiologic sources (acne, trauma, surgery) were treated using a mechanical microneedling device.

Microneedling too often can create more inflammation and pigmentation, and the skin will take even longer to heal. DermaPen for Stretch Marks – Stretch marks are caused by the dermis being torn; DermaPen’s tiny punctures trigger the body’s wound healing response. For example, the A7 and M8 have finer needles than previous models which is ideal for treating scars. In addition, the hyperproliferation of keratinocytes is downregulated by microneedling in acne patients because it overall balances out the cell equilibrium. Other events noted are post-inflammatory hyperpigmentation, aggravation of acne and reactivation of herpes, systemic hypersensitivity, allergic granulomatous reactions and local infections following the use of a nonsterile instrument.

MS-4 is the only dermaroller that has a smaller cylinder, 1 cm length, 2 cm diameter, and subsequently 4 circular arrays of needles (total 96 needles) that have 1. Dermarolling has been used for a wide range of indications with many trials supporting evidence for its usefulness.

It makes use of a rechargeable battery to operate in two modes, namely, the high speed mode (700 cycles/min) and the low speed mode (412 cycles/min) in a vibrating stamp-like manner.The minimum time interval between two sittings of microneedling depends upon the indication for which the procedure is being done as well as the needle length of the dermaroller being used. The stamping motion of a Dermapen also causes less trauma to the epidermis by making smaller holes than the holes made by a dermaroller treatment, resulting in less discomfort and less downtime, also allowing maximum penetration to the dermal layer, further supporting skins natural collagen and elastin production. Another common misconception is that the more bleeding and redness you have after microneedling, the more effective the treatment was.
