Dermaroller
The new dermaroller treatment at Face & Eye is undertaken by Amanda Baker, our specialist aesthetics nurse.
MECHANISM OF ACTION OF THE DERMAROLLER
In this micro-needling procedure the body’s self-healing mechanisms are utilised. The skin reacts to the intrusion of micro-needles like it would react to any other object penetrating the skin but the difference is the size of the object - the micro-needle. The intrusion of the tiny surgical needles of the dermaroller is sensed by skin nerve receptors as an injury stimulus but the needles are so fine and thin that actual tissue damage is extremely unlikely. The injury triggers a healing process cascade. Skin cells, in a radius of 1 to 2 mm around the needle prick channels, 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 fibres. The function of fibroblasts is to migrate to the point of intrusion to facilitate wound closure and healing. The needle prick channels, caused by the micro-needles, close very quickly and no tissue lesion can be detected, and none has to be repaired. The transformation of the wound repair cells is an automatic process. Their final mission is to transform into collagen fibres. They integrate into the existing collagen formation in the upper dermis. This new collagen fibre formation thickens the skin. The thousands of microscopic needle-pricks caused by the dermaroller results in the induced collagen formation becoming confluent and forming 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.
