Tattooing and piercing can cause skin breakdown and bleeding. They produce open wounds and the possibility of infection. Infections at the location can result in long-term deformity, scarring, serious sickness, and even death. Many tattoo colors are comprised of metals and can cause skin irritations and allergic reactions. Never sleep with your tattooed skin exposed, as this can lead to infections. People have died from having tattoos removed. The ink particles can spread throughout the body and may cause other problems such as heart disease, lung disease, and cancer. Tattoos are permanent treatment for pain management purposes only. If you are thinking about getting a tattoo, ask yourself if you really want it.
