Microneedling devices are instruments with technological features, such as many small needles, tips, or pins on the surface, which are repeatedly inserted
and removed into the skin, penetrated into the living skin layers (epidermis and dermis) .
The needles may be attached to a cylinder that is rolled across the skin, project from a flat surface that is "stamped" on the skin, or arranged in a pattern on
the tip of a pen-shaped instrument.
Microneedling devices create many small puncture holes in the skin by moving over the skin repeatedly.
In doing so, these micro-injuries encourage and harness the body’s innate ability to regrow and repair the skin through normal physiological processes and
the skin becomes rejuvenated.
And then the serum can be directly entered into the skin mesoderm through the tiny wound generated by the micro needle, so that the skin can absorb the
MICRONEEDLING microneedling devices are manual, meaning the needles always project from the surface, and they enter the skin when the device is rolled
or stamped on the surface.
MICRONEEDLING microneedling devices use a motor to move needles in and out of the device surface, named electric microneedling device. In some motorized
devices, the health care practitioner can adjust and control the depth and speed of penetration of needles into the skin.
