Serious problems can happen if you try to do a tattoo yourself, have a friend do it for you, or have it done in any unclean environment. Skin infections caused by bacteria, viruses, or fungi can happen if the skin is not cleaned properly, or the ink or needles are contaminated. Sharing needles, ink, or other equipment without sterilization increases your chance of getting HIV, hepatitis B, or hepatitis C.
The American Academy of Dermatology distinguishes five types of tattoos: traumatic tattoos, also called "natural tattoos", that result from injuries, especially asphalt from road injuries or pencil lead; amateur tattoos; professional tattoos, both via traditional methods and modern tattoo machines; cosmetic tattoos, also known as "permanent makeup"; and medical tattoos.
Plenty of cultures from across the globe have used tattoos as a form of expression. Certain cultures have used tattoos as a part of many rites of passage, for beauty, or artistic purposes, as a type of warrior mark, to identify a tribe or a gang, and so on.

The ultimate peak of rugged style has captured in the tribal sleeve tattoo. The comprehensive designs are connected to our ancestors’ rites involving scarification rituals, and they were already around way before tattoos were even accepted by society. Plenty of historians are certain that tribal tattoos were the first form of ink-based body art ever created. A lot of aboriginal and tribal groups have glorified the use of tribal tattoos, to symbolize a boy’s maturity. These designs have often been associated to the state of reaching full adulthood. This type of symbolism is still being used up to this day.
The word tattoo, or tattow in the 18th century, is a loanword from the Samoan word tatau, meaning "to strike". The Oxford English Dictionary gives the etymology of tattoo as "In 18th c. tattaow, tattow. From Polynesian (Samoan, Tahitian, Tongan, etc.) tatau. In Marquesan, tatu." Before the importation of the Polynesian word, the practice of tattooing had been described in the West as painting, scarring or staining.
