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 successive generations of macrophages, 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.[66]

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. The needles are single-use needles that come packaged individually.
Redhat.......its ok little man. I realise you hate yourself and must demean others to feel better about yourself. But I have to disagree with you. I think Ashley is a very sexy woman. But regardless you dont have to think she is. However the fact you went out of your way to spread hate makes it clear you also hate yourself. I hope your figure out your own issues. Maybe you'll enjoy life more
Today's the day, you're ready to commit, and you just know in your heart — it's tattoo time! Now you need help figuring out how to pick a full tattoo sleeve theme. I've been on a mission for Bustle, interviewing tattoo artists all over the Bay Area. My goal has been to learn more about tattoo sleeves so I can help ladies who are ready to go under the gun, but still need more information. I've covered what part of a tattoo sleeve hurts the most and facts to know before getting started. I wrote a piece answering how long does a full sleeve tattoo take and how to deal with aftercare. But I honestly think picking the theme is the most exciting part.
Following discussions with my colleague Professor Don Brothwell of the University of York, one of the specialists who examined him, the distribution of the tattooed dots and small crosses on his lower spine and right knee and ankle joints correspond to areas of strain-induced degeneration, with the suggestion that they may have been applied to alleviate joint pain and were therefore essentially therapeutic. This would also explain their somewhat 'random' distribution in areas of the body which would not have been that easy to display had they been applied as a form of status marker.
Tattoos have also been used for identification in other ways. As early as the Zhou, Chinese authorities would employ facial tattoos as a punishment for certain crimes or to mark prisoners or slaves. During the Roman Empire, gladiators and slaves were 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.[18] Owing to the Biblical strictures against the practice,[19] 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.[20]
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.[86]
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.[21] Moko tattoos were facial designs worn to indicate 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.[22]
