Micro-Needle Therapy with Dermapen
This technique is known as Collagen Induced Technique (CIT). All this is a very complex process, but the principle is quite easy to understand.
In micro-needling, we simply utilize the body’s self-healing mechanisms. It reacts to the intrusion of micro-needles like it would react to any other skin penetrating object. But the difference is the size of the object – the micro-needle. The intrusion of tiny surgical needles (provided they are professionally designed) is sensed by skin nerve receptors as an injury stimulus. But the needles are so fine and thin that tissue damage is unlikely.
The skin integrity actually stays intact. However, this “nerve-stimulus”, transported by electrical signals, triggers the cascade of the healing process.
Skin cells, in a radius of 1 to 2 mm around the pricking channel, release growth signals to undifferentiated cells. These signals in return stimulate the proliferation of new cells, e.g. fibroblasts to transform into collagen and elastin fibers. The task of fibroblasts is to migrate to the point of intrusion for wound closure.
And here comes the trick: The pricking channels, caused by the micro-needles, close very quickly and no tissue lesion can be detected, and none has to be repaired.
The transformation for wound repair cells (e.g. fibroblasts and others) is an automatic process – like a one-way road. Their final mission is to transform into collagen fibers.
Micro-Needling for Collagen Formation
They integrate into the existing collagen formation in the upper dermis. This new fiber formation – in terms of many hundred percent – thickens the skin and fills former atrophic scars.
As single needle prick is not worth mentioning. But if thousands of microscopic small needle-pricks are set, the induced collagen formation becomes confluent and forms a new collagen layer. This body reaction is called neo-collagenesis.
In addition, the inner cells that coat our vessels (endothelial cells), and in particular these of our capillaries, are also stimulated to proliferate. They react to this stimulation by sprouting out new capillaries that in return results in more and better blood supply of the skin. This reaction is called neo-angiogenesis.
The result is new regenerated skin in the treated area. This technique is used to treat wrinkles, hyper pigmentation and scars. There is no downtime and 2 or 3 treatments are recommended per year.
Best results are seen when microneedling combined with PRP.
