Macrophage immune cells in the skin can capture pigments from tattoos and hold them in place, causing tattoos to persist even after new macrophages move in to deal with the contaminants:

[...] That's what French scientists observed from studying tatted mice. In their model of tattoo persistence [open, DOI: 10.1084/jem.20171608] [DX], published Tuesday in the Journal of Experimental Medicine, macrophages — immune cells that ingest foreign or unhealthy debris in the body — play a starring role. Targeting these cells, the authors suggested, might help improve tattoo removal procedures for people.

As a tattoo is given, macrophages descend to capture invading ink. Probably because the ink granules are too bulky for the microscopic Pac-Mans to break down, they hold onto the pigment, your body art shining through their bellies.

With time, these original macrophages die and release their pigments, which get vacuumed up by new macrophages, starting the cycle over, said Sandrine Henri, a researcher at the Immunology Center of Marseille-Luminy who led the study with her colleague Bernard Malissen.

[...] Jared Jagdeo, a dermatologist at the University of California, Davis, has also wondered whether macrophages impede tattoo removal by reabsorbing lasered ink particles. Since 2014, he has performed a laser removal procedure that uses anti-inflammatory ointment to suppress macrophages. "It makes a difference," he said, noting that he often removes tattoos in 10 or fewer treatments [instead of 20].

    Seriously, a tattoo is a sign of a lack of self-respect for one's own body, along with a lack of discretion relative to life choices.

    It might seem cool to get one at the time you get it, but later on it will just be stupid.

    On the other hand, if you think it's cool to have tattoos, then you are an idiot, and your tattoos can warn the world about your idiocy, so that is a positive use for
    a tattoo.

    I don't judge others based on how they dress or otherwise adorn themselves. I judge them on the things they do and say.

    Do you consider those who have pierced ears to be idiots as well? How about those who wear jewelry? Dye their hair? Shave their faces? wear clothes? All of those things are similar to getting a tattoo.

    Just because *you* don't think a tattoo is something worth having doesn't mean that *everyone* who wants/has/gets a tattoo is an idiot.
    That you think so means that *you* are an idiot.

    I know you think I'm just being mean by saying that. I'm not. I'm pointing out your idiocy so that you might stop acting like one.

    So I'll explain, in the hope that you have a few functioning brain cells to understand.

    Anyone who paints all those who have a certain characteristic (like a tattoo or dyes their hair or listens to Nickelback or wears a one-piece bathing suit or just about anything else that people have or do) with a broad brush is an idiot, in my opinion.

    I suspect you disagree with me (mostly because I'm describing you), but perhaps the point is made?

    For the record, I have no tattoos myself, as I don't want/need to modify my body in that way. I don't even wear any jewelry. Nor do I dye my hair. I do shave my facial hair, as I hate that just slightly more than I hate shaving it off. I reluctantly wear clothes, at least when I leave the house, as some folks seem to frown on public nudity for some reason.

    tl;dr: Different people have different ideas about how they wish to adorn themselves. That doesn't make them idiots. You, however, are certainly giving off that vibe, friend.

      How is "permanent deposition of alien material into your dermis" not something you "do"?

      > Do you consider those who have pierced ears to be idiots as well?

      In my experience, thinking negatively about tattoos is very highly correlatedwith thinking negatively about permanent mutilation of ones facial features.

      So if you're trying to trap people into saying something negative about piercings, you have failed, they already express such opinions freely.

      > How about those who wear jewelry?

      That's not permanent, nor a modification of living tissue.

      > Dye their hair?

      That's not permanent, nor a modification of living tissue.

      > Shave their faces?

      That's not permanent, nor a modification of living tissue.

      > wear clothes?

      That's not permanent, nor a modification of living tissue.

      > All of those things are similar to getting a tattoo.

        Personally, I have observed a strong correlation between tattoos and gang activity, and often hang out in prisons.

          I know a lot of people who have tattoos.

          Most of them have never been to prison.

          What's more, I've dated a number of women who have at least one tattoo. None of them have been to prison either.

          In fact, I know very few people who have been in prison. Or in gangs.

            None of the following are necessarily true for a particular woman with a tattoo, but all are more likely:

            smoker
            drinker
            pothead

              She doesn't smoke
              She's not much of a drinker
              She is a pothead

              She's in graduate school at the moment
              She has no criminal record
              She has many plans/goals for the future and is working hard to achieve them
              She doesn't have a lot of savings/assets, but she's a grad student. That's par for the course at her age
              She doesn't have much income, but she's a grad student. That's par for the course at her age
              She doesn't have debt problems
              She has a loving family to whom she is very close. And a great extended family who is happy to help her any way they can, but we don't really need to because she's bright and successful all on her own.

              My niece will make someone a wonderful wife (should she choose to marry. Women aren't just baby factories -- they're fully human with agency and the same right to live their lives as they wish, like any man) someday, and will be a great, loving mother (again, if she chooses to have children) too.

              Times have changed, AC. The fat 50 year old you meet in a bar that's half in the bag and has stretched out tattoos is from a different generation. Back in the day, tattoos were considered to be the province of the low-lifes and criminals. Things are different now.

              Sticking your dick in crazy can be lots of fun! It's just important to protect yourself if you do. You don't have much imagination, do you? More's the pity.

              Then again, your pastor (who is a good friend and mentor, isn't he?) encourages your narrow world view, doesn't he? Is Jesus Christ yo' nigga? [youtube.com]

              Well done in generating a list that taints about 99% of the female population.

              Some are well-founded, there is a positive correlation between having tattoos and being a thrill seeker.
              Being a thrill seeker is positively correlated with several things on your list.

              Here's a list of traits positively correlated with not having a tattoo:
              being unadventurous
              being boring

              That's not necessarily the perfect partner either.

              Here's a handy hint, or even 3, as I'm generous:
              1) if you like tattooed females, prioritise finding a partner from within a demographic with a higher preference for getting tattoos.
              2) if you don't like tattooed females, prioritise finding a partner from within a demographic with a lower preference for getting tattoos.
              3) if you are neutral regarding tattoos on females, don't feel obliged to prioritise finding a partner from within a demographic with an unusual preference for getting tattoos.

    Whilst I'm happy to counter your cowardly counterer (what's the betting that IRL that AC is male, has a tattoo, and feels a little bit more manly because of his tattoo?), I'm just as happy to counter you.

    Tattoos may sometimes be unwise - to tattoo a marginal political belief, or association with some marginal group, on your forehead, at a young age may hinder your job prospects, and your social acceptance at a later age. It may get you into a fight if you enter the wrong bar (I'm thinking M.C. tats, for example). I agree that anyone who does that, and who then complains about rejection, could be labelled an "idiot". Those that get a partner's name tattooed across or under a heart motif are statistically going to be with that tattoo longer than they are with that partner too, which does show a naivete and a lack of foresight. But if they're prepared to carry them around, like medals from successful missions, into later battles, then so be it. But one has to ask what kind of partner considers posession of a stamp from a previous partnership to be superior to lack of posession of same. (Though some "I stole him from X" pride might exist.)

    However, tattoos can be artistic, and can be as much an augmentation of ones appearance as any of the other ways of decorating oneself, albeit in permanent form. They can be gauche, but they can also be tasteful, as can all other ways that humans visually present themselves to each other. Everyone knows they'll fade, they're not that naive. Those who believe a small amount of imagary says something about who they are, and want to say that about themselves, should not be called idiots for actually getting the device that they think says what they want to say about themselves. You're attempting to stamp out a form of self-expression. Like all communication, interpretation is in the mind of the recipient, and if you think all tattoos say "idiot", that's you're right, but that doesn't make you right. Of course, if they think a swallow diving down into their cleavage says "I'm a free spirit, and I'm also sensual", that's their right too, even if many people will interpret it as "I'm a slapper". Fuck knows what my went-out-of-fashion-in-the-early-70s haircut (erm, what's the word "cut" doing in that compound word? No scissors have encountered this for 30 years) says to most people who see it. I have the right to not care about those who judge such things negatively. I extend that right to tattoo bearers, them doing so doesn't make them all idiots.

      I guess the fact that you can get arrested for being in the public without clothes is quite a good reason to wear them.

      Also, during most of the year, I really appreciate the protection they give against the weather conditions. Indeed, for some time of the year, it's not just a question of comfort, but a question of survival to wear clothes whenever you leave the warmth of your home for a non-negligible amount of time.

    a tattoo is a sign of a lack of self-respect for one's own body

    Why would this matter? The body is yours, and this alteration, while permanent, doesn't noticeably degrade the body's abilities (it interferes with some medical monitors, that's the only non-social downside I'm aware of).

    On the other hand, if you think it's cool to have tattoos, then you are an idiot, and your tattoos can warn the world about your idiocy, so that is a positive use for a tattoo.

    This! In places in the US, tattoos are more widespread among non-dumb population, but at least here in Poland, having a tattoo is a strong signifier of being wilfully ignorant and proud of it. This is how criminals and regular low-class (not necessarily money-wise) people mark themselves to stand out. This causes a cycle as the rest of the population: those intelligent, those average, and those who are poor but honest, distance themselves from tattoo-bearers, which in turn reinforces that group's urge to keep away from the normies even more.

    Thus, just like certain kinds of clothing, tattoos are a social signifier. And with current use of that signifier, it's a warning against interacting with such a person. Which is unfair to those who merely made a mistake, thinking a tat can be "cool", but the social convention is so strong that not knowing any better is by itself telling.
