How does microneedling help reduce hyperpigmentation


Medical Micro Needling enables gentle treatment to improve the appearance of the skin. The therapeutic benefit has been proven in several respects and, with the designation collagen induction therapy (CIT), has found consensus among medical experts.

Medical Needling (CIT)

Microneedling is a relatively new therapeutic option that is ideally suited, among other things, for large-area therapy for atrophic scars. Here, fine needles on a roller are used to pierce small perforations into the skin barrier. These repeated micropunctions create multiple small injuries that lead to collagen remodeling. The resulting micropores close again within a few minutes. As a result, the grain structure and height gradually adjust to the surroundings. Since treatments with needle lengths of 0.25 mm and more are painful, the skin area to be treated must be anesthetized beforehand. The treatments can be carried out under surface anesthesia, e.g .: with a cream containing lidocaine with an application time of only 30 minutes (dolocupine).

Medical needling is a minimally invasive form of medical treatment to improve the structure of the skin. Sun-damaged skin, wrinkles, stretch marks and hyperpigmentation can also be treated well. For this purpose, dermarollers with different needle lengths from 0.5 to 1.5 mm and different roller head widths from 10 to 20 mm are used.
All dermarollers used for medical needling are sterile SINGLE-USE INSTRUMENTS and must be disposed of properly according to use and manufacturer's instructions. The treatment is carried out exclusively by trained doctors and their clinical staff. Devices for medical needling are supplied exclusively to doctors and clinical institutions.
The skin of the face has an average thickness of 1.5 mm. For this reason, from an anatomical point of view, dermarollers with needles longer than 1.5 mm are not required (with the exception of burn scars).
To achieve an optimal result, 2 to 3 treatments at an interval of 8-10 weeks are necessary.
The DermaStamp was developed for small and isolated scars. This means that scar treatments can be carried out in just a few minutes.

Which skin problems does the dermaroller help with?
The medical dermaroller shows success in the treatment of acne scars, injury scars and stretch marks. By using it, wrinkles and scars are filled and the poor blood supply to scars is significantly improved; they lose their pale color. The skin is proven to tighten and smooth. Pigment disorders such as age spots or melasma (hyperpigmentation) are visibly reduced.
The home care dermaroller is not suitable for treating scars. It has a stimulating effect on the cell division of the epidermis. The Beauty Mouse is used to treat cellulite.

How does the treatment with the dermaroller work?
Medical dermarollers are unsuitable for household use - treatment may only be carried out by a trained doctor. After a light local anesthetic (in cream form, e.g. Dolocupine) of the skin to be treated, the dermaroller is rolled several times lengthways, crossways and diagonally over the skin with minimal pressure. In this way, the skin receives around 250 micro-punctures per square centimeter. After the treatment, which lasted around 30 minutes, the skin is only slightly reddened. This reddening has completely subsided after a day at the latest. There is no downtime.
When using the Home Care Dermaroller, the top layer of skin is hardly noticeably perforated with extremely short microneedles. The use of the Home Care Dermaroller and Beauty Mouse is painless as there are no nerve cells in the top layer of skin (epidermis). As with the medical device, the user glides along, across and diagonally across the skin with light pressure.

What does the dermaroller do under the skin?
The tiny microneedles of the medical dermaroller create minimal perforations in the skin. The skin registers the puncture as an injury. This triggers the skin's repair function, even though the puncture by the dermaroller is not a real injury, but rather a skin irritation. In this respect, the skin does not react with the formation of scar tissue, as would be the case with an injection needle, for example, but produces growth substances. Treatment with the medical dermaroller, for example, causes the skin to form collagen fibers of type III (have a firming effect) as well as elastin fibers (give the skin elasticity) and new capillaries that promote blood circulation, especially in old scar tissue. Scars and wrinkles are filled in and smoothed from bottom to top. The advantages over so-called skin-removing (ablative) treatment methods are obvious: Instead of removing skin as with laser, dermabrasion or peeling, i.e. making the skin thinner and thus weakening its protective function, treatment with the dermaroller stimulates the build-up of new tissue layers. Apart from the aforementioned reddening of the skin, there are no known side effects and the treatment can be repeated without restriction.
When treating with the extremely short microneedles of the Home Care Dermaroller and the Beauty Mouse, no new collagen is formed, as is the case with the medical Dermaroller. However, the tiny microneedles loosen scale deposits and blockages on the top layer of the epidermis and the pore size is noticeably reduced. The process stimulates cell production, the complexion becomes more transparent and rejuvenated.

How quickly can the first treatment results be seen?
Even after a treatment with the medical dermaroller, an improvement in the complexion of the skin can be noticeable - wrinkles and scars are much less pronounced. After two to four treatments, which should ideally take place every six to eight weeks, acne scars, for example, improve by up to 70 percent. To date, medical professionals have used the Dermarolle® on more than 250,000 patients worldwide and successfully treated acne scars, pigment disorders, burn scars as well as wrinkles and skin aged by the sun.
With regular use of the Home Care Dermaroller developed for home use or the Beauty Mouse - the manufacturer recommends two to three treatments per week - a significant improvement in the complexion of the skin can be achieved.
