The micro needling process facilitates and stimulates the skin’s natural repair and growth processes without causing any scarring or permanent damage. PCI micro-needling with the Environ Medical Roll-Cit is performed under topical anaesthesia. The primary function of this treatment is to cause microscopic breaks in the blood vessels immediately below the surface of the skin (epidermis). As a response, platelets are released. These, in turn, produce a series of growth factors that promote the body’s own production of natural collagen and elastin.
