Microneedling – scars and stretch marks treatment with Dermaroller and Dermapen

Microneedling – scars and stretch marks treatment with Dermaroller and Dermapen

Microneedling or Collagen Induction Therapy. The application of Dermaroller (Fig.2) forms hundreds of microscopic channels in the skin. Following a number of complicated consecutive reactions (hemostasis – inflammation – proliferation – remodeling), fibroblasts, special skin cells, close off the loopholes (tiny channels) that were formed by the Dermaroller needles (Fig.2).

Collagen islands are synthesized within the channels (Fig.3), which are attracted to one another, thus gradually aligning the edges of scars or striae. In this manner an elastic backing of fresh collagen tissue is created on the one hand, decreasing the width of atrophic scars or striae by retracting and elevating their bottom to the skin surface on the other hand (Fig.4).

Collagen fibers of keloids are located differently compared to regular scars. They are located relatively in parallel to the skin surface in regular scars, while chaotically and node-like, resembling a fingerprint in keloids (Fig.6).

Therefore, in order to improve the appearance of pathological scar and reduce its height to be broken randomly arranged collagen fibers, and create new ones, which will be more parallel to the surface of the skin. This task can also be performed through micro needle therapy (Fig.7).
