“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.
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.
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
“massaging tartrazine solution into hairless mouse skin over the course of a few minutes or using microneedling achieves “complete optical transparency in the red region of the visible spectrum”
I know it didn’t happen this way but I like to believe it was someone having their unwashed dorito fingers after lunch, decided to massage a mouse for several minutes, and figuring this out
Some of us can't be trusted with such power. I would personally use invisibility to switch items in people's coat pockets. Keys always in the left? Well now they're in the right pocket!
Yellow 5 is super common (in the US) for things that go inside our bodies. Doritos, Mt Dew, probably Red Bull. When we were kids there was a rumor that it would shrink your dick haha.
Read the ingredients on stuff the next few days and take note of how often you see it. It's probably why they chose it as one of the test substances. It's relatively safe to eat.
What is unknown is how dangerous it is to absorb large amounts into someone's skin.
It's like the illegal weed vape pen issue years ago. People would cut the product with vitamin e to thicken it and also make more money. Vitamin E is safe for human consumption. Turns out its vapor is terrible for lungs. It's quite unsafe for that kind of consumption.
Highly recommend anyone reading check out an app called Yuka. You scan barcodes and it'll give you a score of the ingredients and why things are rated the way they are. Not always 100%, but better than trying to just figure out if carboxymethylcellulose is safe, (it is) let alone pronouncable.
So, I skimmed the article and may have missed it. Why is this anything more that tinkering with and (maybe torturing) mice? What's the actual scientific value here? (Assuming invisibility potion wasn't an actual goal)
They applied a yellow, food-safe dye to the skin of the mice and found it caused light to refract in such a way that their skin became significantly more transparent. An article I read (I did not read this one) listed some potential uses like making veins visible for blood draws and more precise tattoo removal. The dye washed off afterwards.
