Tattoos, those beautiful and permanent works of art, involve injecting ink into the skin, which can trigger an immune response; that’s right, getting inked can affect your body’s defense system. At tattooat.com, we help you understand how your body reacts to tattoos and what you can do to ensure a safe and stunning tattoo experience. Learn about pigment migration, inflammatory responses, and tattoo aftercare.
1. How Does Tattooing Work and What Happens in Your Body?
Tattooing involves injecting insoluble pigments into the dermis, the deeper layer of your skin. After a tattoo, ink particles are either passively transported through the blood and lymph fluids or engulfed by immune cells, which then deposit them in the lymph nodes. The dermis and the draining lymph nodes contain these particles even after healing.
Simply put, a tattoo machine punctures the skin thousands of times to deposit ink. This process triggers an immune response as the body recognizes the ink as a foreign substance and tries to remove it. While some ink remains in the dermis, other particles are captured by macrophages, a type of immune cell.
2. What Exactly Is Tattoo Ink Made Of?
Tattoo pigments typically consist of inorganic metals and their oxides or polyaromatic compounds, generally considered biologically inert. Common metals include nickel, chromium, manganese, and cobalt. Titanium dioxide, a white pigment used to create shades when mixed with colored compounds, is also frequently used. The toxicity of titanium dioxide varies based on its crystal structure, with the photo catalytically active anatase structure producing reactive oxygen species when exposed to daylight.
It’s also worth noting that some tattoo inks may contain impurities or contaminants, such as heavy metals or other chemicals, which can potentially contribute to adverse reactions or health concerns.
3. How Do Tattoo Pigments Affect Your Lymph Nodes?
Research published in Scientific Reports in 2017 provided analytical evidence supporting the transport of organic and inorganic pigments, alongside toxic element impurities, from tattoo ink to the lymph nodes. Scientists at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, used X-ray fluorescence measurements to pinpoint titanium dioxide’s location in the skin and lymphatic system at both micro and nano levels.

The study revealed that organic pigments, heavy metals, and titanium dioxide travel from the injection site to regional lymph nodes. Organic pigments had the broadest size range, with the tiniest (nano) particles reaching the lymph nodes. This highlights the potential for long-term accumulation of tattoo pigments in the body, particularly in the lymphatic system.
4. What Changes Occur in Tissues Near Tattoo Particles?
Researchers detected structural changes in tissues near tattoo particles, including altered ratios of amide I α-helix to β-sheet protein and increased lipid content. These changes suggest that tattoo pigments can affect the surrounding tissue at a molecular level.
The authors concluded that their findings offer strong evidence for the migration and long-term deposition of tattoo pigment, along with conformational alteration of biomolecules, potentially causing cutaneous inflammation and other adverse events related to tattooing. Understanding these effects can help individuals make informed decisions about getting tattoos.
5. How Does the Immune System React to Tattoos?
The dermis, where tattoo ink is deposited, contains blood vessels, lymphatic vessels, nerves, and immune cells such as dermal dendritic cells, macrophages, CD4+ T cells, and innate lymphoid cells. These cells react to damage caused by the tattoo needle injecting pigment, recognizing the ink pigment as a foreign body and initiating an immune response to clear it.
Immediately after tattooing, the skin swells, and while most ink remains in the dermis, some migrates to regional lymph nodes, as discussed earlier.
6. What Role Do Macrophages Play in Maintaining Tattoos?
When tattoo ink remains in the skin, dermal macrophages engulf it and sequester it in their vacuoles, where enzymes cannot decompose it. A 2018 study determined the origin, identity, and dynamics of the skin myeloid cells responsible for capturing and retaining tattoo pigment particles.

The study showed that these myeloid cells are exclusively dermal macrophages, not resident dermal cells. Furthermore, analysis demonstrated that tattoo pigment particles undergo cycles of capture-release-recapture without risking tattoo loss at the injection site. This cycle ensures the permanence of tattoos.
7. How Do Macrophages Ensure the Permanence of Tattoos?
Researchers used diphtheria toxin to selectively delete cells expressing CD64, a monocytic marker found on monocytes, macrophages, myeloid cell precursors, and follicular dendritic cells. By engineering mice to have the diphtheria receptor under the control of the CD64 gene, they specifically targeted all myeloid cells for ablation (deletion).
The study found that macrophage death results in the release of trapped pigment. However, two days after diphtheria toxin treatment, circulating macrophages replenished the macrophage pool, which had been replenished by bone marrow-derived monocytes. These newly derived macrophages then engulf the free ink released by the prior macrophage population, continuing the process indefinitely and ensuring tattoo permanence.
Therefore, the study concluded that long-term tattoo persistence depends on macrophage renewal rather than macrophage longevity.
8. Can Tattoos Boost the Immune System?
A 2016 study measured immune function using secretory immunoglobulin A (SIgA) and cortisol in the saliva of 29 participants to investigate the ‘inoculation hypothesis’ of tattooing. This hypothesis suggests that tattooing inoculates the immune system, providing increased protection against stressors that produce soft tissue damage.
The tattoo experience was measured by the number of tattoos, lifetime hours tattooed, years since the first tattoo, percentage of body covered, and number of tattoo sessions.
9. What Did the Study Reveal About Immune Function and Tattoos?
Researchers observed an inverse relationship between SIgA and cortisol, with less immunosuppression of SIgA in those with more tattoo experience. Those without pre-existing tattoos experienced a greater strain on their immune system, evidenced by a larger dip in their SIgA levels.
The data suggest that the body habituates to the external insult of tattooing over time. However, the authors noted that individuals with healthy immune systems heal faster, increasing their likelihood of subsequent tattooing experiences. While tattoos might not directly boost the immune system, they may help the body adapt to external stressors.
10. What Are the Potential Risks and Side Effects of Tattoos?
While many people get tattoos without experiencing adverse effects, there are potential risks and side effects to be aware of:
10.1. Allergic Reactions
Some individuals may develop allergic reactions to tattoo inks, particularly those containing certain dyes or pigments. These reactions can manifest as:
