    “We strongly discourage attempting this on human skin, as the toxicology of dye molecules in humans, particularly when applied topically, has not been fully evaluated,” he tells Popular Science.

    I feel like it’s only a matter of time before this becomes a TikTok trend.

      Wait, let me get this straight: they’re not even sure if Yellow #5/Tartrazine is safe to be applied topically, but it’s FDA-approved to be ingested?

        Things absorbed through the skin may be in a different state when they reach your bloodstream than things that are ingested. The process of digestion can break down a lot of things that would otherwise be harmful, but aren’t similarly filtered when absorbed through the skin.

        It’s also why some medicines are taken by swallowing a pill, and some are taken by dissolving a tablet under your tongue.

            There’s a difference between having Dorito dust on your fingers and having it massaged/injected into your skin via microneedling. It’s closer to “don’t tattoo yourself with Dorito dust” than it is “don’t let it get on you.”

              I mean, people tattoo with phosphorous (I think it was phosphorous) to get glow in the dark tattoos and that shit’s a carcinogen! People gonna people.

                Some glow in the dark chemicals are called phosphors, and while they’re named after phosphorus, they usually do not contain any phosphorus, zinc sulfide for example. These are the kinds of things you might find on a watch face or stickers or whatever that need to absorb light from some other source first.

                To make it even more confusing, phosphorus isn’t actually phosphorescent, its glow is from chemiluminescence, the result of a chemical reaction.

                And for what it’s worth, stuff that glows under a black light is fluorescent.

                I don’t think phosphorus has ever been used for glowing tattoos, and if it was I’m pretty sure no one is still using it. We’re well outside of my realm of expertise, but it should also be considered that how a chemical enters your body can make a difference in how toxic it is too, there’s a whole lot of chemistry at work in your body, and ingesting something and absorbing it through digestion isn’t necessarily going to have the same effect as absorbing it through your skin, there’s a reason different medications have to be taken oral, allowed to dissolve under your tongue, given as a suppository, intravenously, intramuscularly, subdermally, etc. that said, I’m pretty sure phosphorus is bad no matter how you put it into someone’s body.

                My understanding is that phosphates are no longer used, and that most “glow in the dark” tattoos are actually glow under UV tattoos now.

              Additionally, we’re talking about using a significantly higher concentration of the dye that you’re going to find in Dorito dust.

        I believe have a problem with the cuboid bone in my foot, and I’ve been waiting over a year for a podiatrist. I wonder if I can see if there’s a crack in it myself… It’s close enough to the surface that it should be visible if that really works? I wonder how no one who works with the stuff has ever noticed this before

          I’d think a fracture big enough to be a problem would be immediately apparent, but if it’s just a hairline, this probably isn’t clear enough to show it…

          OTOH, if you’re around Portland, I know a super good podiatrist.

          But they could just do an X-ray of that. I would have thought other procedures such as tissue injuries would be what benefits from a procedure like this which would otherwise require an expensive follow-up

              Sounds like someone forgot to put in your paper work. I’d follow it up if I were you.

                Paper work is the problem, my doctor’s office sucks. My actual doctor is great. Literally the best experience with a doctor we’ve ever had, but the office is terrible. Still waiting on an ultrasound of my gallbladder for 8 months, waiting on testosterone shots for low t for 1.5 years, plus other shit, and that’s just me. My mom had to wait 3 months for colostomy supplies because they couldn’t manage to fax the prescription correctly. She had to wash out and reuse ostomy bags using skin safe glue and tape to stick them on. But they’re the only ones around here. It’s a big corp that bought out all the other practices that didn’t shut down, so they are literally the only PCP in the area. Even the urgent care is owned by the same people. No matter which office you go to it’s all the same problems. :/ but at least our doctor is good. Lol.
