The Dermapen’s sterile needle tips are designed to be disposable and for are for a single-use only, to prevent cross-contamination and infection. The needle tips cannot be be properly decontaminated due to the materials used in the construction of the needle tip cartridge itself. We strongly recommend -against- re-using needle tip cartridges, as patient safety is of paramount importance. The Dermapen’s design permits the user to change the needle tip cartridge after each use, at a very low consumable cost with each treatment. A low consumable cost, combined with little to no downtime for the patient, makes Dermapen an ideal solution.
