Health effects of tattoos

A variety of health effects can result from getting a tattoo. Because the process of tattooing requires breaking the skin barrier, tattooing carries inherent health risks, including infection and allergic reactions. Modern tattoo artists reduce such risks by following strict health precautions, including working with single-use disposable needles and sterilising tattoo machines and other equipment after each use. Many jurisdictions require tattoo artists to undergo periodic bloodborne pathogen training, such as is provided through the Red Cross and the U.S. Occupational Safety and Health Administration.

Dermatologists have observed rare but severe medical complications from tattoo pigments in the body, and have noted that people acquiring tattoos rarely assess health risks prior to receiving their tattoos. Some medical practitioners have recommended greater regulation of pigments used in tattoo ink. The wide range of pigments currently used in tattoo inks may create unforeseen health problems.
