MICRONEEDLING IN THE MEDICAL AND COSMETIC FIELD
ABSTRACT Differences between non- invasive, minimally-invasive, and invasive microneedling are described in the following article. The boundaries of cosmetic and medical microneedling are clearly defined. Regarding the depth of skin penetration no difference is made between medical and cosmetic
microneedling, only the intended use of the treatment is relevant. The cosmetic microneedling treatment contributes to the wellness and beauty of the skin, whereas medical microneedling treatment contributes to the improvement of the disease condition of the skin. During the medical treatment, healthcare professionals may only use

HE SKIN CONSISTS OF THE EPIDERMIS, dermis, and subcutis. Skin thickness can vary in every region of the body, with the epidermis varying between 0.03 mm up to 2.0 mm in thickness depending on the skin area. Generally, the epidermis
amounts to 4–8% of the skin thickness depending on the ethnic group1
. Depending . The thickness of the dermis is
between 0.5 mm to 1.5 mm and scientific studies describe the combined thickness of the epidermis and dermis to range between 0.5 to 2.0 mm2
on the fat content the thickness of the subcutis can vary between 0.5 mm to 3 cm at the abdomen.
Microneedling instruments and devices The conventional microneedling instrument is the so-called needle roller. Needle rollers are manual instruments with a handle and a cylinder, on which sharp needles with a diameter of 0.3 mm to 0.4 mm are fixed. When the instrument is rolled over the skin, the needles will penetrate the skin to different depths depending on the pressure, skin tension, and needle length, causing micro-injuries. Needle
rollers create approximately 30–50 punctures per second during an appropriate application. Through repeated applications across selected skin areas approximately 250–300 punctures per cm2
are
Heinz Freier and Andreas Pachten evaluate the application, mode of action, and distinction of medical and cosmetic microneedling in Europe
approved medical compounds, instruments, and devices with an intended medical use. The regulatory background that creates the basis for the distinction of medical and cosmetic microneedling is described in this article and can help manufacturers and practitioners likewise to gain certainty in the area of non- medical microneedling.
