IMPORTANT
Before we go into more details, we would like to emphasise that the induction of body's own new collagen is a medical procedure and should only be performed by trained and licensed skin care professionals. The Collagen-Induction-Therapy (CIT) by micro-needling the skin requires special medical Dermarollers and medical knowledge. As human skin has an average thickness of 1.5 mm, Dermaroller needle lengths range from 0.3 to 1.5 mm. Any longer needles – often offered by copiers of the Original - are contraindicated! Needles longer than 0.25 mm cause pain and require a pre-anaesthetisation of the skin. In order to avoid infections and other unpleasant experiences, a medical procedure should always be performed in a clinical environment!
Although the medical Dermaroller treatment may look so easy - under NO circumstances treat yourself! Without knowledge of skin anatomy, sterility and handling the instrument, you may experience negative side effects and severe damage of your skin! Medical Dermarollers are SINGLE USE invasive instruments. Do NOT reuse them! You may experience severe infections!
If copiers of the Original tell you the opposite – don’t believe it! Trust your physician – trust in our knowledge! Trust the team of the Genuine Dermaroller!
As a certified manufacturer of Medical Devices we only supply Top Quality to authorised professionals and clinics.
If you feel it is worthwhile to buy Roller Copies from the Internet for self treatment and in order to save some Dollars, this is fine with us. But always keep one point in mind: What about liability in case you run into problems? Think about it!
MECHANISM OF ACTION IN MICRO-NEEDLING
All this is a very complex process, but the principle is quite easy to understand.
In micro-needling we simply utilise the body 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 fibres. 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 fibres. They integrate into the existing collagen formation in the upper dermis. This new fibre 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.
