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].

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

    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.

    If you can't predict a big fat "oh, no, they're not" coming, you're gonna be shocked...

    What's your point?

    Do you think you have the right to control how others adorn their bodies, whether permanent or not?

    If so, you're an ass.

    If not, why are you bothering, unless you're just looking to pick a fight?

      My point is that my parent poster's argummentation was ill thought out, containing various forms of illogic.

      I conclude he was the supplier of one of the downmods I got.
      And given the content of your post, I conclude you are him again.

      Thinking that this is a fight rather than an argument implies that you know the argument is lost.

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

    I consider it a warning that it may be wise to avoid contact. Like in nature, brightly colored things are often not wise to mess with.

      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.

      Perhaps you should upgrade either the places you hang out or the people you hang out with. Just a crazy thought.

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

        smoker
        drinker
        pothead
        even worse drugs
        has an STD
        obese
        infidelity/cheater
        low level of education
        criminal
        doesn't plan for the future
        doesn't have savings/assets
        doesn't have much income
        has debt problems
        has a dysfunctional family

        Obviously this is not wife material. You're risking STDs, child support, police raids, fights with her, fights with her friends, and so on. Don't stick your dick in crazy.

          My 21 year old niece has a tattoo.

          She doesn't smoke
          She's not much of a drinker
          She is a pothead
          She doesn't do even worse drugs
          She doesn't has an STD
          She's not obese
          She doesn't do the infidelity/cheater thing
          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.
