A tattoo is a form of body modification, made by inserting indelible ink into the dermis layer of the skin to change the pigment.
The Oxford English Dictionary gives the etymology of tattoo as, "In 18th c. tattaow, tattow. From Polynesian tatau. In Tahitian, tatu." The word tatau was introduced as a loan word into English; its pronunciation was changed to conform to English phonology as "tattoo". Sailors on later voyages both introduced the word and reintroduced the concept of tattooing to Europe.
The first written reference to the word, "tattoo" (or Samoan "Tatau") appears in the journal of Joseph Banks (24 February 1743 – 19 June 1820), the naturalist aboard Captain Cook's ship the HMS Endeavour: "I shall now mention the way they mark themselves indelibly, each of them is so marked by their humor or disposition".
The word "tattoo" was brought to Europe by the explorer James Cook, when he returned in 1771 from his first voyage to Tahiti and New Zealand. In his narrative of the voyage, he refers to an operation called "tattaw". Before this it had been described as scarring, painting, or staining.
Tattoo enthusiasts may refer to tattoos as "ink", "pieces", "skin art", "tattoo art", "tats", or "work"; to the creators as "tattoo artists", "tattooers", or "tattooists"; and to places where they work as "tattoo shops", "tattoo studios", or "tattoo parlours".
Usage of the terms "skin art", "tattoo art", "pieces", and work" is gaining greater support][, with mainstream art galleries holding exhibitions of both conventional and custom tattoo designs. Beyond Skin, at the Museum of Croydon, is an example of this as it challenges the stereotypical view of tattoos and who has them. Copyrighted tattoo designs that are mass-produced and sent to tattoo artists are known as "flash", a notable instance of industrial design. Flash sheets are prominently displayed in many tattoo parlors for the purpose of providing both inspiration and ready-made tattoo images to customers.
The Japanese word irezumi means "insertion of ink" and can mean tattoos using tebori, the traditional Japanese hand method, a Western-style machine, or for that matter, any method of tattooing using insertion of ink. The most common word used for traditional Japanese tattoo designs is Horimono. Japanese may use the word "tattoo" to mean non-Japanese styles of tattooing.
Anthropologist Ling Roth in 1900 described four methods of skin marking and suggested they be differentiated under the names "tatu", "moko", "cicatrix", and "keloid".
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.
According to George Orwell, coal miners could develop characteristic tattoos owing to coal dust getting into wounds. This can also occur with substances like gunpowder. Similarly, a traumatic tattoo occurs when a substance such as asphalt is rubbed into a wound as the result of some kind of accident or trauma. These are particularly difficult to remove as they tend to be spread across several different layers of skin, and scarring or permanent discoloration is almost unavoidable depending on the location. In addition, tattooing of the gingiva from implantation of amalgam particles during dental filling placement and removal is possible and not uncommon. Another example of such accidental tattoos is the result of a deliberate or accidental stabbing with a pencil or pen, leaving graphite or ink beneath the skin.
Many tattoos serve as rites of passage, marks of status and rank, symbols of religious and spiritual devotion, decorations for bravery, sexual lures and marks of fertility, pledges of love, punishment, amulets and talismans, protection, and as the marks of outcasts, slaves and convicts. The symbolism and impact of tattoos varies in different places and cultures. Tattoos may show how a person feels about a relative (commonly mother/father or daughter/son) or about an unrelated person. Today, people choose to be tattooed for artistic, cosmetic, sentimental/memorial, religious, and magical reasons, and to symbolize their belonging to or identification with particular groups, including criminal gangs (see criminal tattoos) or a particular ethnic group or law-abiding subculture. Some Māori still choose to wear intricate moko on their faces. In Cambodia, Laos, and Thailand, the yantra tattoo is used for protection against evil and to increase luck.][
In the Philippines certain tribal groups believe tattoos have magical qualities, and help to protect their bearers. Most traditional tattooing in the Philippines is related to the bearer's accomplishments in life or rank in the tribe.][
Extensive decorative tattooing is common among members of traditional freak shows and by performance artists who follow in their tradition.][
People have also been forcibly tattooed. A well-known example is the identification system for inmates in Nazi concentration camps during the Holocaust. The Nazis introduced the practice of tattooing at Auschwitz in 1941 in order to identify the bodies of registered prisoners in the concentration camps. During registration, they would pierce the outlines of the serial-number digits onto the prisoners’ arms. Tattoos have also been used for identification in other ways.][ For example, during the Roman Empire, Roman soldiers were required by law to have identifying tattoos on their hands in order to make it difficult to hide if they deserted. Gladiators and slaves were likewise tattooed, exported slaves were tattooed with the words "tax paid", and it was a common practice to tattoo "Stop me, I'm a runaway" on their foreheads. Emperor Constantine I banned tattooing the face around AD 330 and the Second Council of Nicaea banned all body markings as a pagan practice in AD 787.
In the period of early contact between the Māori and Europeans, the Maori people hunted and decapitated each other for their moko tattoos, which they traded for European items including axes and firearms. Moko tattoos were facial designs worn by women and men to indicate their lineage, social position, and status within the tribe. The tattoo art was a sacred marker of identity among the Maori and also referred to as a vehicle for storing one's tapu, or spiritual being, in the afterlife.
Tattoos are sometimes used by forensic pathologists to help them identify burned, putrefied, or mutilated bodies. As tattoo pigment lies encapsulated deep in the skin, tattoos are not easily destroyed even when the skin is burned.][
Tattoos are also placed on animals, though rarely for decorative reasons. Pets, show animals, Thoroughbred horses, and livestock are sometimes tattooed with identification and other marks. Pet dogs and cats are often tattooed with a serial number (usually in the ear, or on the inner thigh) via which their owners can be identified.][
Also, animals are occasionally tattooed to prevent sunburn (on the nose, for example). Such tattoos are often performed by a veterinarian, and in most cases the animals are anesthetized during the process. Branding is used for similar reasons and is often performed without anesthesia, but is different from tattooing as no ink or dye is inserted during the process.][
The cosmetic surgery industry continues to see a trend of increased popularity for both surgical and noninvasive procedures (Gimlin 2002; Sullivan 2001).
When used as a form of cosmetics, tattooing includes permanent makeup and hiding or neutralizing skin discolorations. Permanent makeup is the use of tattoos to enhance eyebrows, lips (liner and/or lipstick), eyes (liner), and even moles, usually with natural colors, as the designs are intended to resemble makeup.][
Medical tattoos are used to ensure instruments are properly located for repeated application of radiotherapy and for the areola in some forms of breast reconstruction. Tattooing has also been used to convey medical information about the wearer (e.g., blood group, medical condition, etc.). Additionally, tattoos are used in skin tones to cover vitiligo, a skin pigmentation disorder.][
Tattooing has been practiced for centuries in many cultures, particularly in Asia, and spread throughout the world.][ The Ainu, an indigenous people of Japan, traditionally had facial tattoos. Today, one can find Atayal, Seediq, Truku, and Saisiyat of Taiwan, Berbers of Tamazgha (North Africa), Yoruba, Fulani and Hausa people of Nigeria, and Māori of New Zealand with facial tattoos.][
Tattooing spread among Polynesians and among certain tribal groups in Africa, Borneo, Cambodia, Europe, Japan, the Mentawai Islands, MesoAmerica, New Zealand, North America and South America, the Philippines, and Taiwan. Indeed, the island of Great Britain takes its name from tattooing; Britons translates as "people of the designs", and Picts, the peoples who originally inhabited the northern part of Britain, literally means "the painted people".
The modern revival in tattooing stems from the voyage of Captain James Cook in the late 1700s. Cook's Science Officer and Expedition Botanist, Sir Joseph Banks, returned to England with a tattoo. Banks was a highly regarded member of the English aristocracy and had acquired his position with Cook by putting up what was at the time the princely sum of some ten thousand pounds in the expedition. In turn, Cook brought back with him a tattooed Raiatean man, Omai, whom he presented to King George and the English Court. Many of Cook's men, ordinary seamen and sailors, came back with tattoos, a tradition that would soon become associated with men of the sea in the public's mind and the press of the day. In the process sailors and seamen re-introduced the practice of tattooing in Europe and it spread rapidly to seaports around the globe.
As many tattoos were stimulated by Polynesian and Japanese examples, amateur tattoo artists were in great demand in port cities all over the world, especially by European and American sailors. The first documented professional tattoo artist in the USA was Martin Hildebrandt, a German immigrant who arrived in Boston, Massachusetts in 1846. Between 1861 and 1865, he tattooed soldiers on both sides in the American Civil War. The first documented professional tattooist in Britain was established in Liverpool in the 1870s. Tattooing was an expensive and painful process, and by the 1870s had become a mark of wealth for the crowned heads of Europe.
Since the 1970s, tattoos have become a mainstream part of global and Western fashion, common among both sexes, to all economic classes, and to age groups from the later teen years to middle age. For many young Americans, the tattoo has taken on a decidedly different meaning than for previous generations. The tattoo has "undergone dramatic redefinition" and has shifted from a form of deviance to an acceptable form of expression. In 2010, 25% of Australians under age 30 had tattoos.
Tattooing involves the placement of pigment into the skin's dermis, the layer of dermal tissue underlying the epidermis. After initial injection, pigment is dispersed throughout a homogenized damaged layer down through the epidermis and upper dermis, in both of which the presence of foreign material activates the immune system's phagocytes to engulf the pigment particles. As healing proceeds, the damaged epidermis flakes away (eliminating surface pigment) while deeper in the skin granulation tissue forms, which is later converted to connective tissue by collagen growth. This mends the upper dermis, where pigment remains trapped within fibroblasts, ultimately concentrating in a layer just below the dermis/epidermis boundary. Its presence there is stable, but in the long term (decades) the pigment tends to migrate deeper into the dermis, accounting for the degraded detail of old tattoos.
Some tribal cultures traditionally created tattoos by cutting designs into the skin and rubbing the resulting wound with ink, ashes or other agents; some cultures continue this practice, which may be an adjunct to scarification. Some cultures create tattooed marks by hand-tapping the ink into the skin using sharpened sticks or animal bones (made like needles) with clay formed disks or, in modern times, needles.
The most common method of tattooing in modern times is the electric tattoo machine, which inserts ink into the skin via a single needle or a group of needles that are soldered onto a bar, which is attached to an oscillating unit. The unit rapidly and repeatedly drives the needles in and out of the skin, usually 80 to 150 times a second. This modern procedure is ordinarily sanitary. The needles are single-use needles that come packaged individually. The tattoo artist must wash his or her hands and must also wash the area that will be tattooed. Gloves must be worn at all times and the wound must be wiped frequently with a wet disposable towel of some kind. The equipment must be sterilized in a certified autoclave before and after every use.
The Government of Meiji Japan had outlawed tattoos in the 19th century, a prohibition that stood for 70 years before being repealed in 1948. As of June 6, 2012 all new tattoos are forbidden for employees of the city of Osaka. Existing tattoos are required to be covered with proper clothing. The regulations were added to Osaka's ethical codes, and employees with tattoos were encouraged to have them removed. This was done because the strong connection of tattoos with the yakuza, or Japanese organized crime, after an Osaka official in February 2012 threatened a schoolchild by showing his tattoo.
Current cultural understandings of tattoos in Europe and North America have been greatly influenced by long-standing stereotypes based on deviant social groups in the 19th and 20th centuries. Particularly in North America tattoos have been associated with stereotypes, folklore, and racism. Not until the 1960s and 1970s did people associate tattoos with such societal outcasts as bikers and prisoners. Today, in the United States many prisoners and criminal gangs use distinctive tattoos to indicate facts about their criminal behavior, prison sentences, and organizational affiliation. A teardrop tattoo, for example, can be symbolic of murder, or each tear represents the death of a friend. At the same time, members of the U.S. military have an equally well-established and longstanding history of tattooing to indicate military units, battles, kills, etc., an association which remains widespread among older Americans. Tattooing is also common in the British Armed Forces. A study conducted in 2004 among 500 adults between ages 18 and 50 found an explicit link between tattooing and criminality. 72 percent of respondents with face, neck, hands, or fingers tattoos have spent more than three days in jail, compared to 6 percent of the non-tattooed population. Depending on vocation tattoos are accepted in a number of professions in America. Although companies across many fields are increasingly focused on diversity and inclusion, tattoo flaunting is still probably best reserved for post-work hours.
The Romans tattooed criminals and slaves, and in the 19th century released US convicts and British army deserters were identified by tattoos. Prisoners in Siberian and Nazi concentration camps were tattooed with an identification number. Today, many prison inmates still tattoo themselves as an indication of time spent in prison.
Native Americans also used tattoos to represent their tribe.
Insofar as this cultural or subcultural use of tattoos predates the widespread popularity of tattoos in the general population, tattoos are still associated with criminality. Tattoos on the face in the shape of teardrops are usually associated with how many people a person has murdered. Although the general acceptance of tattoos is on the rise in Western society, they still carry a heavy stigma among certain social groups. Tattoos are generally considered an important part of the culture of the Russian mafia.
The prevalence of women in the tattoo industry, along with larger numbers of women bearing tattoos, appears to be changing negative perceptions. A study of "at-risk" (as defined by school absenteeism and truancy) adolescent girls showed a positive correlation between body modification and negative feelings towards the body and low self-esteem; however, the study also demonstrated that a strong motive for body modification is the search for "self and attempts to attain mastery and control over the body in an age of increasing alienation."
Many studies have been done of the tattooed population and society's view of tattoos. In June 2006, the Journal of the American Academy of Dermatology published the results of a telephone survey which took place in 2004. It found that 36% of Americans ages 18–29, 24% of those 30-40, and 15% of those 41-51 had a tattoo. In September 2006, the Pew Research Center conducted a telephone survey which found that 36% of Americans ages 18–25, 40% of those 26-40 and 10% of those 41-64 had a tattoo. They concluded that Generation X and Generation Y are not afraid to express themselves through their appearance, and tattoos are the most popular form of self-expression. In January 2008, a survey conducted online by Harris Interactive estimated that 14% of all adults in the United States have a tattoo, slightly down from 2003, when 16% had a tattoo. Among age groups, 9% of those ages 18–24, 32% of those 25-29, 25% of those 30-39 and 12% of those 40-49 have tattoos, as do 8% of those 50-64. Men are slightly more likely to have a tattoo than women.
Because it requires breaking the skin barrier tattooing carries health risks including infection and allergic reactions. Modern tattooists reduce risks by following universal precautions working with single-use items and sterilizing their equipment after each use. Many jurisdictions require that tattooists have blood-borne pathogen training such as that provided through the Red Cross and OSHA. As of 2009 (in the United States) there have been no reported cases of HIV contracted tattoos.
In amateur tattooing, such as that practiced in prisons, however, there is an elevated risk of infection. Infections that can theoretically be transmitted by the use of unsterilized tattoo equipment or contaminated ink include surface infections of the skin, fungal infections, some forms of hepatitis, herpes simplex virus, HIV, staph, tetanus, and tuberculosis.
Tattoo inks have been described as "remarkably nonreactive histologically". However, cases of allergic reactions to tattoo inks, particularly certain colors, have been medically documented. This is sometimes due to the presence of nickel in an ink pigment, which triggers a common metal allergy. Occasionally, when a blood vessel is punctured during the tattooing procedure, a bruise/hematoma may appear.
While tattoos are considered permanent, it is sometimes possible to remove them, fully or partially, with laser treatments. Typically, black and some colored inks can be removed more completely than inks of other colors. The expense and pain associated with removing tattoos are typically greater than the expense and pain associated with applying them. Pre-laser tattoo removal methods include dermabrasion, salabrasion (scrubbing the skin with salt), cryosurgery, and excision - which is sometimes still used along, with skin grafts for larger tattoos. These older methods, however, have been nearly completely replaced by laser removal treatment options. Tattoos and piercings have been around for a very long time but those who take the decision to get a tattoo lightly (or who decide to get a name other than that of their own name,parents or children’s name) will almost always decide to cover or remove said tattoo at some point in their lives.
Ink or coloring applied to the surface of skin is sometimes referred to as a "tattoo." Mehndi, also known as a henna, is a traditionally Hindu method of staining the skin. Modern techniques include ink transfers on sheets of paper and tattoos drawn on skin with ballpoint pen.
