“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?

[–] Chozo@fedia.io 82 points 2 months ago (1 children)

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.

Does it mean I'm supposed to eat that with gloves,? This is not making sense

[–] EldritchFeminity@lemmy.blahaj.zone 75 points 2 months ago (3 children)

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.

[–] Fondots@lemmy.world 23 points 2 months ago

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.

[–] SturgiesYrFase@lemmy.ml 3 points 2 months ago

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

Eagerly awaiting my sick-ass radium tattoo

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

[–] synae@lemmy.sdf.org 1 points 2 months ago

Chopsticks, my friend.

Vinegar isn't good for the skin either. But healthy if ingested.

eating Doritos with dorito dust all over fingers

Well….uh, ok?

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

[–] jordanlund@lemmy.world 5 points 2 months ago (1 children)

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.

[–] dharmacurious@slrpnk.net 4 points 2 months ago (1 children)

Sadly, I'm in Tennessee. But if you know of anything for 1000 a month or less I'll move there tomorrow!

It can be done! Keep in mind too, I bet our wages are higher than TN too + no sales tax.

[–] dharmacurious@slrpnk.net 7 points 2 months ago

Wtaf, how are the prices in Portland better than in my little hick town in Tennessee? Jeeze

Just looked it up, and I'll make almost exactly 3 more dollars an hour, too. Honestly, this is worth genuinely considering

[–] dharmacurious@slrpnk.net 3 points 2 months ago (1 children)

One more thing, how concerned should I be about falling into the ocean if the cascades fault goes?

[–] jordanlund@lemmy.world 2 points 2 months ago (1 children)

Ocean is about an hour away to the west, OTOH there's a giant volcano an hour to the east.

Bonus, Portland has a dormant volcano inside city limits:

[–] dharmacurious@slrpnk.net 2 points 2 months ago (1 children)

Maybe not falling into the ocean, but does the idea of earth quakes, like "the big one" ever freak you out? I'd imagine I'd get used to little ones pretty quick, but the society-collapsing earthquake built up in my brain is very scary! Lol

Also, contacted my work and asked about transferring out there. We might actually be doing this!

[–] jordanlund@lemmy.world 2 points 2 months ago (1 children)

PM me if you come out! I know a great podiatrist! We actually just saw him today!

Earthquakes are infrequent. I've felt a couple. More of a deal if you're at the coast because they have tsunami alarms. Feels like a big truck driving behind you.

Oh, and it's always "the coast", not "the beach". People don't really "go to the beach" like in California, LOL:

[–] dharmacurious@slrpnk.net 2 points 2 months ago (1 children)

Can't watch that yet, no earbuds at the moment. Lol. Do y'all not swim in the ocean? I grew up in Virginia Beach, VA. We went to the beach. Like 9 months out of the year. Lol.

[–] jordanlund@lemmy.world 2 points 2 months ago (1 children)

It's way, way too cold most of the year.

There are also dangers like sneaker logs. I love the coast and visit it when I can, but when you're a kid growing up here they always teach you "Don't turn your back to the ocean" because it has no pity and can and will straight up kill you.

https://www.weather.gov/safety/ripcurrent-waves

"The coastline of Northern California, Oregon and Washington State are steep, tree lined, and have cold to frigid water temperatures. These beaches are quite unlike the flat, broad beaches of Southern California with their inviting warm water temperatures. The steep slopes of the Northwest’s coastlines are much more likely to cause sneaker waves; the trees that line the cliffs can wind up in the swift ocean currents running along the shoreline; while the cold to frigid temperatures, depending on the season, can induce cold water paralysis for anyone caught in these northwestern ocean waters.

While in Southern California people at the beach are in bathing suits or light summer clothes wading and swimming in warm waters with open beaches, in contrast in the North they wear heavier clothes, coats, shoes, and boots due to the cooler temperatures and in autumn and winter those waters are frigid. Encounters with the waves in Southern California, with its warm water temperatures and broad beaches, might simply knock a person over on the beach, but in the North the cold water temperatures could induce cold water paralysis rendering the individual helpless to escape the pull of the receding wave returning to the ocean.

Always respect the ocean on the beaches of the North Coast of California, Oregon, Washington with their steep, rugged tree lined coasts, and frigid ocean temperatures."

[–] dharmacurious@slrpnk.net 2 points 2 months ago (1 children)

Makes sense. I did assume it was swimmable during the summer. I just figured it was like in Maine and New Hampshire where it was a short season. Do y'all ever get to swim anywhere besides pools? I'm a southern kid, I grew up swimming in lakes, rivers, the ocean. Just about everything but the swamps lol

[–] jordanlund@lemmy.world 2 points 2 months ago (1 children)

Tons of rivers and lakes, but you still have to be careful. Generally folks are out on the first hot day of the year and forget the water is still 50°. LOL.

There's this place called "High Rocks" and every year people are like "Well, start the clock until the first drowning..."

[–] dharmacurious@slrpnk.net 2 points 2 months ago

Jesus. Yeah, we get some drownings here, but nothing like that. There's this one spot in the county I used to live in called the blue hole, where the water is always 45 degrees, and kids dare each other to jump in. They freeze up or cramp and drown.

[–] Smoogs@lemmy.world 2 points 2 months ago (1 children)

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

[–] dharmacurious@slrpnk.net 1 points 2 months ago (1 children)

They could... But for over a year I've been waiting :/

[–] Smoogs@lemmy.world 2 points 2 months ago (1 children)

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

[–] dharmacurious@slrpnk.net 1 points 2 months ago

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.

[–] it_depends_man@lemmy.world 1 points 2 months ago* (last edited 2 months ago)

It also means "we don't know (yet)" so there is a chance it's not that toxic.
