Here's what they discovered. In order for a tattoo to be permanent, ink has to get into the dermis, the tissue just underneath the outer layer of your skin, called the epidermis. This is done by making thousands of tiny pricks in the skin. To do that, a tattoo artist uses a handheld machine that has a needle affixed to it.
How does tattoo ink stay in the skin? Tattoos are injected into the second layer of our skin, the dermis, which rests underneath the protective layer of the epidermis.
So, we have shown that tattoo pigment can spread through the mouse's blood system as well as through the lymphatic system." The ink pigment was detected inside special cells in the liver that remove toxic substances, called Kupffer cells. These cells appeared to be in the process of "eating" the pigment particles, Sepehri said.
Epithelial tissue is used in the Epidermis. This tissue is used to form the outer layer of skin. This tissue effects tattooing because tattoos are on your top layer of skin. Connective tissue is in the Dermis.
A tattoo in the epidermis wouldn’t last – it would likely disappear in just a few weeks. The dermis is very sensitive.
However, few people take time to understand the science behind the art. It’s important to know what really happens to your body when you get a tattoo to fully understand the process of what goes on under the skin.
Modern tattoo machines work quickly; they can pierce the skin to inject ink at a frequency of up to 3,000 pricks per minute.
Tattoos are permanent images in the skin, delivered by needles injecting ink into the dermis. This tissue is just underneath the outer layer of your skin, called the epidermis. The ink is injected into the dermis by a machine that delivers thousands of tiny pricks per minute via needle.
This process is complex: Macrophages are why tattoos fade over time AND part of what makes them permanent. Some macrophages swallow ink particles and send them out through the lymphatic system. However other macrophages remain in the dermis and allow the injected ink to remain visible.
This isn’t the real reason why tattoos are permanent, though. Basically, from the first piece of the needle, your tattoo and your body’s immune system are locked in a tug that never stops. The secret to a permanent tattoo is, in fact, a permanent inflammation. When a tattoo needle punctures the skin, it rips through the epidermis, ...
When a tattoo needle punctures the skin, it rips through the epidermis, the outer layer of skin, and spills ink in the dermis, the inner layer of skin which is flooded with blood vessels and nerves. With each penetration, the immune system is alerted there’s a wound going on and immune system cells are sent to the site.
Some of these are macrophages which gobble up the ink in an attempt to clean the area. What’s left of the ink becomes absorbed by skin cells called fibroblasts. Most of the fibroblasts and macrophages alike become suspended in the dermis where they’re locked permanently.
Most people think a tattoo is permanent because the ink goes so deep into the skin that it cannot be washed off. It turns out there’s a lot more to it than that.
Tattoo needles penetrate through the outer layer of your skin (called the epidermis), and deliver the ink into the deeper layer of skin (called the dermis), which contains nerves and blood vessels.
Special cells called macrophages come to the rescue, eating up the dye in an attempt to "clean up" the inflammation it's causing.

Because tattooing is essentially making thousands of tiny wounds in the skin, the body's immune system goes into overdrive, sending special blood cells called macrophages to the site of the tattoo to engulf the foreign ink particles.
The artist dips the needle in the ink, turns on the motor that moves the needle, and applies the moving needle to the skin. The sharp needle pricks the skin quickly and repeatedly, dragging the ink clinging to it down into the dermis. Smarter Every Day.
Smarter Every Day. The tattoo needle is actually one piece of metal that has several ends to it. A needle can have three ends or as many as 25. Each type of needle can achieve different effects. Needles with fewer ends are used for outlining, while needles with more ends can be used for shading or coloring.
Tattoo artist Leah Farrow told Smarter Every Day that the two most common machines are the rotary and the coil. The two different machines work differently but do essentially the same thing — moving the needle. The rotary machine's motor moves a rotating circular bar, which moves the needle up and down.
This is part of the body's attempt to clean up and it's also the reason tattoos fade over time, but it also plays a part in making tattoos permanent. Once a macrophage consume an ink particle, it goes back through the lymphatic highway and brings the consumed particles to the liver for excretion.
Instagram/iamlilbub. Getting a tattoo is a notoriously painful process but that doesn't stop all that many people from getting their skin inked. Luckily for them, tattoo machines have come a long way from the tools used in the past.
Let’s start with a quick biology lesson on skin. There’s 3 main layers in our skin : The Epidermis , the Dermis and the Subcutaneous. The Epidermis Layer is in charge of sensing our environment and acting as a barrier to keep infectious organisms out. The epidermis is constantly making new skin cells.
The skin cells travel up to the top layer and flake off, about a month after they form. The Dermis Layer is in charge of many bodily functions including growing hair, bringing blood to your skin, making sweat and also holds the nerves. In our opinion, its most important feature, being home to your professional tattoo!
To make a tattoo permanent, a tattoo artist punctures the skin with hundreds of needle pricks. Each prick delivers a deposit of ink into the dermis, the layer of skin that lies below the epidermis , which is populated with blood vessels and nerves.
The ink that's not cleared away by special repair cells, called macrophages, stays in the dermis within trapped macrophages or skin cells called fibroblasts. It then shows through the skin, perhaps spelling out "Mom" or featuring ...
The scientists detected particles of cobalt, nickel and chromium, which are sometimes added to organic tattoo pigment as preservatives, at the lymph nodes.
Carbon black, which is one of the most common ingredients in tattoo inks, appears to break down readily into nanoparticles and end up in the lymph nodes, the study found. The team also looked at titanium dioxide (TiO2), which is a common ingredient in a white pigment usually combined with other colors to create certain shades.
Research on mice suggests some particles of ink may also end up in the liver. "When you inject particles into the skin, some travel to the lymph nodes within minutes," Ines Schreiver, a chemist with the German Federal Institute for Risk Assessment in Berlin,told Live Science.

But long-term studies in humans are needed to definitively link tattoo ink in lymph nodes to any harmful effect. The ingredients within tattoo ink itself also remain largely unknown and under- regulated. A study from Denmark in 2011 found that 10 percent of unopened tattoo ink bottles tested were contaminated with bacteria.
It's also not known if it's harmful for tattoo pigment particles to accumulate in the lymph nodes. So far, evidence suggests such deposits may cause enlargement of the lymph nodes and some blood clotting. But long-term studies in humans are needed to definitively link tattoo ink in lymph nodes to any harmful effect.
Tattoos are injected into the second layer of our skin, the dermis, which rests underneath the protective layer of the epidermis. This alone isn’t enough to make tattoos permanent however , as the damage caused by the needle brings our immune response, including our foreign body-eating white blood cells, to the site. Unfortunately for the white blood cells, the injected pigment molecules are too large to be consumed, meaning the ink can hang around indefinitely.
Unfortunately for the white blood cells, the injected pigment molecules are too large to be consumed, meaning the ink can hang around indefinitely. The permanency of tattoos is a double-edged sword, as they can be difficult to remove.
