1 The Derma pen is an automated micro-needling device with a disposable tip cartridge that is made up of 12 micro-needles, which uses proprietary technology to penetrate vertically into the skin. 2 The stamping action of the Derma pen’s vertical tip creates invisible micro-injuries to the skin, while stimulating the skin’s natural ability to heal itself and increase the production of new collagen. 3 In doing so, these micro-injuries encourage and harness the body’s innate ability to regrow and repair the skin through normal physiological processes and the skin becomes rejuvenated and refreshed.
