“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.

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

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.

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

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

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