Biotechnology employs scientific studies of microorganisms in relation to metabolic, physiological and genetic aspects, providing support for the recognition of isolated microorganisms. For this reason, we analysed the Dermaroller in microbiological terms. These are plastic cylinders made up of micro-needles. There are a wide variety of brands of these rollers on the market, with variations in the number of needles and length, and they are used in just one application, with the instrument pre-sterilised by gamma irradiation, as the equipment is discarded after use. It is forbidden to reuse or sterilise the Dermaroller, as the needles lose their thread after use and during the autoclaving process they lose their pointed shape and can easily detach from the roller.
