What influence have the fine needles of the Dermaroller on the epidermis?

Epidermal Proliferation

In recent research we found out that even the short needles of the homecare Dermaroller (C8) with a needle length of only 0.18 to 0.20mm (0.0078 inch) have a positive effect on the epidermis without any skincare products. Many people believe that the epidermis consists just of "dead" skin cells, but this is not the case. It is the contrary! Especially in the lowest layer, the basal membrane, we can observe very vital processes.

What influence have the fine needles of the Dermaroller on the epidermis?

The renewal cycle of the epidermal cells is between 2 and 4 weeks. In aged skin this process is prolonged. From research in the laboratories of MatTek™ and Owen Biosciences™ (USA) with the Dermaroller® we know that even short needles influence the cell communication by electrical signals, especially in the basal membrane. Transmitted Growth Factors (TGF) signals stimulate and accelerate the cell proliferation of keratinocytes, basal cells, etc. This stimulation caused by Dermarolling the skin reduces the proliferation cycle and increases the cell production of undifferentiated and differentiated cells. This results in an increase of the epidermis of 30% and more. The skin (over time) is pushed upward and finally forms the stratum corneum.
With a slower cell cycle, aged skin often has a matte, grayish appearance. This is caused by the slowed cell proliferation and also the keratin scales building up on the surface. This lack of transparency is the substantial optical difference between young and old skin. These matte scales (1 or 2 layers out of about 20) are removed by the fine needles of the Dermaroller.

The Home Care Dermaroller combines several advantages:

Increase of the epidermal cells and the improvement of transparency.
In order to achieve this effect, the Dermaroller may be used only 2 to 3 times per week. Verifiably suitable skin care products can support this effect.
The following observations were reported to us by users of the homecare Dermaroller after they have used it for 2 to 3 months:

1. Reduction of pore skin / reduction of sebum production (oil flow).
2. A reduction of monthly breakouts.
3. A softer and more transparent skin.
4. A stronger, resilient, more protected skin.
