NEEDLING FROM ITS ORIGINS TO MODERN APPLICATIONS – dentrocasa magazine, September 2013

Needling is a regenerative dermatology technique born a few years ago that consists of treating the skin with special micro needles in order to induce a cellular stimulus that increases the production of collagen and elastin.
Originally, needling was performed by the doctor through a roller (dermaroller) equipped with micro needles and manually scrolled repeatedly in the areas to be treated. In the modern version, an electromedical device is used that accurately modulates the depth of action, the penetration vector and speed. Compared to the old devices, the advantages are that the extreme speed of vibration makes the procedure painless and the control of the penetration vector allows a homogeneous and effective treatment. The dermaroller is more painful, the needles penetrate obliquely into the skin, generating more evident trauma and the control is entrusted completely to the operator’s hand without guarantee of evenness.
The mode of action of needling is based on the cell stimulation of the epidermis and of the dermis as a result of which coagulation factors and inflammatory cytokines are released, which induce an increase in the production of new collagen and elastic fibres. The skin regenerates and becomes more turgid with a clear reduction of the finest roughness.
In aesthetic medicine, skin needling is one of the possible treatment tools for the reduction of photoaging and chronoaging skin damage. Its more specific functions include the treatment of post-acne scars, stretch marks and the most hostile wrinkles of the upper lip and the décolleté.
The treatment is performed in the clinic with the support of a topical anaesthetic and the session lasts for between 10 and 30 minutes depending on the extent of the area to be treated. At the end of the session, the patient is left with redness in the affected area that will disappear after two or three days in the most serious cases.
The first results are noticeable after a couple of weeks but the stimulus to the production of collagen is maintained for some months. When appropriate, it is suggested to repeat the treatment after one month.
