Epidermis increases in thickness
In recent research we found out that even the short needles of the Home
Care 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 skin care
products. Many people believe that the epidermis consists 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.
In order to highlight and to see what happens in the epidermis with an
average thickness of 0.1 mm (0.0034 inch), please refer to the
up-scaled scheme.
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 esults in an
increase of the keratin layer of 30% and more. The keratin layer is
pushed upward and finally forms the so-called stratum corneum. This
last layer of skin scales with an average thickness of one hundredth of
a millimeter (0.0004 inch) finally forms the first protection layer (barrier) of
our skin towards environmental influences.
Aged skin often has a matte, grayish appearance. This is caused by the
slowed cell proliferation and 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.
* IMPORTANT NOTE: So called “Light” Peelings (with lower grade chemical acid) or Micro-Dermabrasion – both ablative procedures - are very common theses days to achieve a fresher look of the skin. Both procedures remove several layers (up to 10 or more) of the horny scales. These horny cell layers are considered to be “dead cells” and have no more function. But this is an erroneous assumption! They are former keratinocytes that only have lost their cell nucleus, but still have a very vital function: They filter UVA and UVB rays! If they are removed chemically or mechanically UVA- and B rays have a much higher destructive impact in the vital lower epidermal cells with possible irreparable skin damage and permanent pigmentation loss. In order to prevent such cell damage and to avoid increased photo-sensibility after an ablative procedure, it is a MUST to apply a sunscreen with a factor of 30 or more for several weeks.
The Home Care Dermaroller combines several advantages in one:
Increase of the epidermal cells and 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 Home Care Dermaroller after they have used it for 2 to 3 months:
1. Reduction and normalization of big pores in connection with a reduction of sebum production.
2. A significant cutback of transient acne associated with the monthly cycle.
(We assume that the fine needles carry away excessive keratin and keep the sebum ducts open.
3. A softer and more transparent skin.
