Terms


The word "tattoo" is traced to the Samoan word tatau, meaning to mark or strike twice . Sailors traveling the Pacific who encountered Samoans, and who were fascinated by the Samoan tatau, mistakenly translated the word "tatau" into the modern tattoo. In Japanese Japanese language

 the word used for traditional designs or those that are applied using traditional methods is irezumi , while "tattoo" is used for non-Japanese designs.

Tattoo enthusiasts may refer to tattoos as tats, ink, art or work, and to tattooists as artists. The latter usage is gaining support, with mainstream art galleries holding exhibitions of tattoo designs and photographs of tattoos.

Tattoo designs that are mass-produced and sold to tattoo artists and studios and displayed in shop are known as flash.

History


Tattooing has been a Eurasian practice at least since Neolithic times. Mummies bearing tattoos and dating from the end of the second millennium BCE have been discovered in Xinjiang, West China. Tattooing in Japan is thought to go back to the Paleolithic era, some ten thousand years ago. Various other cultures have had their own tattoo traditions, ranging from rubbing cuts and other wounds with ashes, to hand-pricking the skin to insert dyes.

Purpose


Tattoos have served 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.

Such tattoos are often performed by the veterinarian him or herself and in most cases, the animals are anaesthetized during the process. Branding is used for similar reasons and is often performed without anaesthesia, but is different from tattooing as no ink or dye is inserted during the process.

. The growth in tattoo culture has seen an influx of new artists into the industry, many of whom have technical and fine art training. Coupled with advancements in tattoo pigments and the ongoing refinement of the equipment used for tattooing, this has led to an improvement in the quality of tattoos being produced. Movie stars, models, popular musicians and sports figures are just some of the people in the public eye who are tattooed, which in turn has fueled the acceptance of tattoos. During the 2000s 2000s

, the presence of tattoos became evident within pop culture, inspiring television shows such as A&E's Inked and TLC's Miami Ink.


In many traditional cultures tattooing has also enjoyed a resurgence, partially in deference to cultural heritage. Historically, a decline in traditional tribal tattooing in Europe occurred with the spread of Christianity Christianization

. A decline often occurred in other cultures following European efforts to convert aboriginal and indigenous people to Western religious and cultural practices that held tattooing to be a "pagan" or "heathen" activity. Within some traditional indigenous cultures, tattooing takes place within the context of a rite of passage between adolescence and adulthood.

A poll conducted online between July 14 and 20, 2003 , found that 16% of all adults in the United States have at least one tattoo. The highest incidence of tattoos was found among the gay, lesbian and bisexual population and among Americans ages 25 to 29 years and 30 to 39 years . Regionally, people living in the West were more likely to have tattoos. Democrats were more likely to have tattoos than Republicans and Independents ; approximately equal percentages of males and females have tattoos.

Negative associations


Secular attitudes

Some employers, especially in professional fields, still look down on tattoos or regard them as contributing to an unprofessional appearance. Tattoos can therefore impair a wearer's career prospects, particularly when inked on places not typically covered by clothing, such as the hands, neck or face. It is not unusual for tattoo artists to refuse to tattoo these very conspicuous areas.

In some cultures, tattoos still have negative associations despite their increasing popularity, and are generally associated with criminality in the public's mind; therefore those who choose to be tattooed in such countries usually keep their tattoos covered for fear of reprisal. For example, many businesses such as gyms, hot springs and recreational facilities in Japan Japan

It is widely believed that one of the initiation rites in becoming a triad member is silently withstanding the pain of receiving a large tattoo in one sitting, usually performed in the traditional "hand-poked" style. One reason the Chinese associate tattoos with criminals is because historically criminals who were released from prison for minor crimes were given a tattoo on their face as a "warning sign" to other people.

In the United States many prisoners and criminal gangs use distinctive tattoos to indicate facts about their criminal behavior, prison sentences, and organizational affiliation. This cultural use of tattoos predates the widespread popularity of tattoos in the general population, so older people may still associate tattoos with criminality. At the same time, members of the U.S. military have an equally established and longstanding history of tattooing to indicate military units, battles, etc., and this association is also widespread among older Americans.

Procedure



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 Scarification

. Some cultures create tattooed marks by hand-tapping the ink into the skin using sharpened sticks or animal bones or, in modern times, needles. Traditional Japanese tattoos are still "hand-poked," that is, the ink is inserted beneath the skin using non-electrical, hand-made and hand held tools with needles of sharpened bamboo or steel.

The most common method of tattooing in modern times is the electric tattoo machine Tattoo gun

Aftercare

Tattoo artists, and people with tattoos, vary widely in preferred methods of caring for new tattoos. Some artists recommend keeping a new tattoo wrapped for the first twenty-four hours, others suggest removing temporary bandaging after a few hours. Many western tattooists advise against allowing too much contact with water for the first few days or weeks; in Japan, in contrast, a new tattoo is often bathed in very hot water early and often.

General consensus for care advises against removing the scab that forms on a new tattoo and avoiding exposing tattoos to the sun for extended periods, which can contribute to fading. Various products may be recommended for application to the skin, ranging from those intended for the treatment of cuts, burns and scrapes, to petroleum jelly or lanolin. In recent years, specific commercial products have been developed for tattoo aftercare. In other cases, the client will be advised to use no products on a new tattoo.

Tattoo removal

While tattoos are considered permanent, it is possible, to varying degrees, to remove them. Complete removal, however, is often not possible, and the expense and pain of removing them typically will be greater than the expense and pain of applying them. Some jurisdictions will pay for the voluntary removal of gang tattoos.

Tattoo removal is most commonly performed using lasers that react with the ink in the tattoo, and break it down. The broken-down ink is then absorbed by the body. This technique often requires many repeated visits to remove even a small tattoo, and may result in permanent scar Scar

ring.

A newer method of removal is by tattooing glycolic acid Glycolic acid

Glycolic acid is the smallest a-hydroxy acid [i]. ... 

 into the skin with a tattoo machine: the acid pushes the ink to the surface of the skin in the scab, which is later removed. This method purportedly scars less than laser techniques. Glycolic acid is also used for facial peels; when used for tattoo removal, a lower percentage mix is used.

Some wearers opt to cover an unwanted tattoo with a new tattoo. This is commonly known as a coverup or cover-up. An artfully done cover-up may render the old tattoo completely invisible, though this will depend largely on the size, style, colours and techniques used on the old tattoo. Some shops and artists use laser removal machines to break down and lighten undesired tattoos to make coverage with a new tattoo easier.

Overall, green-based ink is the most difficult to remove. Black ink is most readily broken down by the laser, and unprofessional tattoos done at home are the easiest ones to remove, due to the low quality of ink used, as well as the ineffective manner in which they were applied.

Health risks


Because it requires breaking the skin barrier, tattooing may carry health risks, including infection and allergic reactions. In the United States, for example, a person who receives a tattoo will generally be prohibited from donating blood for 12 months .

Modern western tattooers reduce such risks by following universal precautions, working with single-use items, and sterilizing their equipment after each use. Many jurisdictions require that tattooists have bloodborne pathogen training, such as is provided through the Red Cross International Red Cross and Red Crescent Movement

Infection

 and bodily fluids, diseases may be transmitted if the instruments are used on more than one person without being sterilized. However, infection from tattooing in clean and modern tattoo studios employing single-use needles is rare. In amateur tattoos, such as those applied in prisons, however, there is an elevated risk of infection. To address this problem, a program was introduced in Canada as of the summer of 2005 that provides legal tattooing in prisons, both to reduce health risks and to provide inmates with a marketable skill. Inmates will be trained to staff and operate the tattoo parlors once six of them open successfully; the program, however, was discontinued by the new Canadian government in 2006.

Although the FDA technically requires premarket approval of inks; because of limited resources, it has not actually approved the use of any ink for tattoos. The first known study to characterize the composition of these inks was started in 2005 at Northern Arizona University .

However, research by Shellock and Crues reports adverse reactions to MRI and tattoos in a very small number of cases. Wagle and Smith also documented an isolated case of Tattoo-Induced Skin Burn During MR Imaging.

Temporary tattoos

Temporary tattoos are not really tattoos. Rather, they are a type of body sticker, like a decal. They are generally applied to the skin using water to temporarily transfer the design to the surface of the skin. Temporary tattoos are easily removed with soap and water or oil-based creams, and are intended to last only a few days.

Magician Penn Jillette claims in his book "Penn & Teller's How to Play in Traffic" that he had a special tattoo made on his arm that used no pigment . Penn states that the tattoo left a red scar that had a discenrable pattern, but would heal to near invisibility after five or six years.

Airbrush tattoos is another popular form of temporary tattoos. This process involves using a stencil design and blowing paint through the stencil onto the skin. This form of tattoo lasts approximately a week.

Forensics

Tattoos are sometimes utilized by forensic pathologists to help them identify burned, putrefied, or mutilated bodies.
Tattoo pigment is deep enough in the skin that even severe burns will often not destroy a tattoo.
