The principle of micro-needling (dermaroller) consists in exploiting the natural ability to self-healing.


The body reacts to the introduction of micro-needles, how to react to any object that penetrates the skin. The difference is the size of the object. The inclusion of small and thin surgical needles (specially designed) means that the cutaneous nerve receptors receive the same type of stimulus and react as if they were in the presence of a superficial skin lesion. The needles are so thin that can cause tissue lesions.

This “nerve stimulation” triggers the healing process.

Skin cells, within 1 to 2 mm around the needle, send a signal to the growth of undifferentiated cells. In turn, these signals stimulate the proliferation of new cells, for example, fibroblasts that are transformed into collagen and elastin.

The task of migrating fibroblast is the point of needle insertion.
The final mission is to transform these cells into collagen, which integrates with the existing one in the epidermis.

While a single puncture has no effect, hundreds of microscopic needles induce sufficient collagen formation.

Even the cells lining the blood vessels (endothelial cells) and in particular those of the capillaries are stimulated. They react to this stimulus by inducing the formation of new capillaries, thereby enhancing the vascularization of the skin.

This technique can be applied to any area of the body, in contrast to ablative techniques . Depending on the conditions of the skin an initial course of 2-3 treatments is recommended.

Since the newly formed collagen requires an aging time average of six weeks, an interval of about two months between the treatments is recommended.

The day after the treatment you can resume the social life, with the aid of a slight make-up.
