Does Tattoo Ink Get In Your Bloodstream? Yes, some tattoo ink particles can migrate into the bloodstream during the tattooing process, raising concerns about potential health implications; tattooat.com is here to help you understand the science behind tattoo ink and its journey within your body, ensuring you’re well-informed about the art of tattooing. By exploring ink migration, lymphatic system interaction, and long-term health implications, we aim to provide clear, actionable insights, offering you the knowledge to make informed decisions, consider alternative inks, and understand permanent makeup safety.
1. The Tattooing Process and Ink Deposition
1.1. How Tattoos Are Applied
Tattoos are created by injecting ink into the dermis, the layer of skin beneath the epidermis. Tattoo machines use needles to puncture the skin, depositing ink with each puncture. According to research from Portland State University’s Art Department, in July 2025, traditional hand-poked tattoos are experiencing a resurgence, prized for their connection to ancient traditions. This process ensures the tattoo’s permanence, as the dermis cells are more stable than those in the epidermis, which constantly sheds.
1.2. What Happens to the Ink After Injection?
Once the ink is deposited, not all of it stays in place. Some ink particles are captured by immune cells called macrophages, which attempt to clear the foreign substance. While most of the ink remains within these macrophages and skin cells in the dermis, some particles can migrate. Ines Schreiver, a chemist with the German Federal Institute for Risk Assessment in Berlin, noted that some particles travel to the lymph nodes within minutes of injection.

1.3. The Role of Macrophages
Macrophages are crucial in the body’s response to tattoos. These immune cells engulf ink particles in an attempt to remove them. However, because the particles are often too large for the macrophages to break down, the ink remains trapped within the cells, contributing to the tattoo’s visibility. As Dr. Arisa Ortiz, a dermatologist and director of laser and cosmetic dermatology at U.C. San Diego Health, explains, the ink is engulfed by skin or immune cells and then sticks around in the dermis.
2. Ink Migration: Lymphatic System and Bloodstream
2.1. How Ink Travels Through the Body
Research has shown that some tattoo ink particles migrate from the dermis through the lymphatic system and into the bloodstream. The lymphatic system, a network of tissues and organs that help rid the body of toxins, carries these particles to the lymph nodes. A study published in Scientific Reports highlighted that pigmented and enlarged lymph nodes have been noticed in tattooed individuals for decades.
2.2. The Lymphatic System’s Role
The lymphatic system filters waste and toxins from the body, including some of the tattoo ink particles that migrate from the skin. These particles can accumulate in the lymph nodes, causing them to become enlarged and discolored. In some instances, this discoloration has been mistaken for signs of cancer, as detailed in a 2015 report in the journal Obstetrics and Gynecology.
2.3. Evidence of Ink in the Bloodstream
A May 2017 study published in the journal Dermatology provided evidence that tattoo pigment can enter the bloodstream. Researchers tattooed mice with black and red ink and, about a year later, found ink pigment in their lymph nodes and liver cells. According to Mitra Sepehri, lead author of the research, the pigment has to go through the blood to reach the liver. This indicates that tattoo pigment can spread through the bloodstream.
3. Chemical Analysis of Tattoo Ink in Lymph Nodes
3.1. First Chemical Analyses on Human Lymph Nodes
A team of German and French scientists conducted the first chemical analyses on tattoo ink collected from human lymph nodes. They analyzed lymph nodes from cadavers with tattoos and compared them to those without tattoos. The study revealed that nanoparticles, measuring less than 100 nanometers across, were most likely to migrate to the lymph nodes.
3.2. Common Ink Ingredients Found in Lymph Nodes
The researchers found that carbon black, a common ingredient in black tattoo inks, readily breaks down into nanoparticles and ends up in the lymph nodes. They also detected titanium dioxide (TiO2), a white pigment often used to create shades, in the lymph nodes. While TiO2 particles were larger than those of carbon black, they still migrated to the lymph nodes.
3.3. Detection of Heavy Metals
Disturbingly, the study also found potentially toxic heavy metals, such as cobalt, nickel, and chromium, in the lymph nodes. These metals are sometimes added to organic tattoo pigments as preservatives. According to Ines Schreiver, these are not things you want to have permanently deposited in your body.
4. Potential Health Implications
4.1. Accumulation in the Liver
The research on mice showed that tattoo pigment could accumulate in the liver. The ink pigment was detected inside Kupffer cells, which are responsible for removing toxic substances. While this study was conducted on mice and may not directly translate to humans, it raises concerns about the potential for similar accumulation in human livers.
4.2. Enlargement of Lymph Nodes
The accumulation of tattoo ink particles in the lymph nodes can lead to their enlargement. While it is not yet known if this enlargement is harmful in the long term, evidence suggests it may cause blood clotting. Long-term studies are needed to determine the definitive link between tattoo ink in lymph nodes and any harmful effects.

4.3. Unknown Long-Term Effects
The long-term effects of tattoo ink migration are still largely unknown. While some studies have identified the presence of ink particles in various organs, the potential health risks associated with this migration require further investigation. As Mitra Sepehri noted, even if tattoo ink can be deposited in the liver, it is still unknown if it’s harmful, as it may pose no risk.
5. Regulation and Composition of Tattoo Ink
5.1. Lack of Regulation
The ingredients within tattoo ink are largely unknown and under-regulated. A 2011 study from Denmark found that 10 percent of unopened tattoo ink bottles were contaminated with bacteria. Additionally, a 2012 Danish Environmental Protection Agency study revealed that 1 in 5 tattoo inks contained carcinogenic chemicals.
5.2. FDA Oversight
In the United States, tattoo ink manufacturing is overseen by the U.S. Food and Drug Administration (FDA) as a cosmetic. However, the FDA has traditionally not exercised regulatory authority for color additives in tattoo inks due to other competing public health priorities and a previous lack of evidence of safety problems.
5.3. Need for More Testing
There is a growing consensus that more testing is needed on both the tattooing process and the ink itself to understand potential reactions in the skin and optimize the safety of tattoos. As Dr. Arisa Ortiz stated, people have tattooed their bodies for thousands of years, and they are not going to stop, so we need more testing.
6. Tattoo-Related Skin Reactions and Infections
6.1. Common Skin Reactions
Tattoo-related skin reactions and infections are a known risk of getting a tattoo. These reactions can range from mild irritations to severe allergic reactions. Red tattoo ink, in particular, is often associated with nasty skin reactions.
6.2. Investigating Ink Ingredients
Researchers are beginning to investigate the specific ink ingredients associated with tattoo-related skin reactions and infections. By analyzing skin biopsies of human patients, they hope to identify the chemical components that cause these adverse reactions. As Ines Schreiver explained, describing a pigment as red means nothing to a chemist; we need to analyze the chemistry.
6.3. Importance of Proper Tattoo Aftercare
Proper tattoo aftercare is essential to prevent infections and minimize the risk of adverse reactions. This includes keeping the tattooed area clean and moisturized, avoiding sun exposure, and following the specific instructions provided by the tattoo artist.
7. Addressing Concerns and Seeking Professional Advice
