Not Just Art, Study Reveals Tattoos Affect the Body's Immune System

JAKARTA - Tattoos are no longer taboo. From small symbols to full images on the body, tattoos have become a common form of self-expression in various circles. However, behind the art that is attached to the skin, a number of recent studies reveal that tattoos have the potential to affect the body's immune system in ways that have rarely been realized.

A scientific study shows that tattoo ink is not just a dye under the skin. Tattoo pigments can interact directly with immune cells and trigger an inflammatory response over a certain period of time.

"When tattoo ink is injected into the skin, the body immediately recognizes it as a foreign substance. The immune system will react and this process does not always stop after the tattoo wound heals," said one of the researchers in the study, quoted from the Science Alert page.

In the process of making tattoos, ink is injected into the dermis layer, a skin layer rich in immune cells. These cells try to clean up the ink pigment, but because the size is too large, the ink cannot be completely removed from the body.

As a result, the pigment is locked in the skin cells and immune cells that make the tattoo permanent. However, this process also triggers immune system activity in no short time.

The research found that immune cells that absorb tattoo ink can remain active and trigger inflammation in surrounding tissues, including in the lymph nodes, for weeks to months.

"We see signs of inflammation in the lymph nodes even up to two months after the tattooing process," explained the researcher.

The quite surprising findings come from the results of a study that links tattoos to the body's response to vaccines. In certain conditions, the presence of tattoo pigments in the injection area of the vaccine can affect the way the immune system responds to the vaccine.

"Tattoos seem to interfere with the communication signals between immune cells. In some cases, this is associated with a lower immune response to certain vaccines," said the researcher.

However, experts stressed that this does not mean that tattoos make vaccines dangerous or unsafe. The findings show that tattoo pigments can affect immune mechanisms in certain situations.

One of the main factors highlighted is the chemical content in tattoo ink. Many of the pigments used today were originally developed for industrial purposes, such as vehicle paint or plastics, not to be injected into the human body.

Some inks are known to contain small amounts of heavy metals, such as nickel and chromium, as well as organic compounds that can potentially trigger allergic reactions or chronic inflammation.

"The problem is not only with the tattoo itself, but with the accumulation of chemicals that stay in the body for a long time," said the researcher.

Until now, there has been no strong evidence linking tattoos directly to serious diseases such as cancer in humans. However, scientists warn that many diseases develop over decades, so the long-term impact of tattoos still needs to be studied further.

Allergic reactions, prolonged itching, swelling, and granulomas are still the most frequently reported health risks, especially in red ink.

"Tattoos are relatively safe for most people, but that doesn't mean there are no risks. The long-term effects still hold many questions," said the researcher.
