Before understanding how Micropen TR tattoo removal works, it is helpful to understand the nature of a tattoo. A tattoo is applied to the skin using an electric tattoo machine containing needles that rapidly and repeatedly puncture the skin and insert pigment into the dermal layer. The dermal layer of your skin is below the top layer, known as the epidermis. As a result, tattoos are not easy to remove—at least they never used to be. Further adding to the permanency of tattoos are the metallic compounds found in tattoo inks. These metallic compounds include: • Copper • Manganese • Lead • Mercury So now that you know exactly what happens when you get a tattoo, let’s talk about what happens when you regret a tattoo! The number of sessions required to remove a tattoo is highly variable and therefore can never be guaranteed.
