The term “microneedling” refers to punctures made briefly in the skin with tiny microneedles. The micropores that are formed in this process close back up within
a few minutes. The clinical procedure of microneedling is called Collagen Induction Therapy (CIT).
The medical Dermaroller treats stretch marks and scars from acne and injuries with successful results. It can be used to fill in wrinkles and scars, and improve poor circulation in scars; they’ll lose their pale colouring. Skin becomes demonstrably tighter and smoother. Pigment disorders such as age spots or melasma (hyperpigmentation) are visibly reduced.
The medical Dermaroller’s tiny microneedles create very small perforations in the skin. The skin registers these punctures as an injury. This triggers the skin’s repair function, even though the punctures made by the Dermaroller aren’t really an injury, but more like skin irritation. In this respect, the skin doesn’t react by forming scar tissue, as would be the case with an injection needle, but instead produces growth agents.
For example, treatment with the medical Dermaroller causes the skin to form type III collagen fibres (which have a firming effect) as well as elastin fibres (which give the skin elasticity) and new capillaries, which promote circulation, especially in old scar tissue. Scars and wrinkles are filled and smoothed from below. The advantages in comparison to “ablative” treatment methods are obvious: Unlike lasers, dermabrasion, or skin peels, which make the skin thinner and thus weaken its protective function, Dermaroller treatment stimulates the building of new layers of tissue.
Aside from the skin reddening mentioned above, there are no known side effects and the treatment can be repeated indefinitely.
