to clarify on the damage a bit, duct tape is thick and non-permeable enough that it makes a hard air seal against your skin. that plus the adhesive being somewhat abrasive means the top layers of skin just start dying. if you’ve ever used a salicylic acid pad or something of the sort for warts, it’s a very similar effect.
even a little bit of prolonged use and you’ll end up with a persistent rash kind of thing. too long and you get what look like bedsores. the damage is cumulative as more fresh skin is exposed, and it will take longer than you think it should to heal.
it’s also one of the only ways to ACTUALLY get rid of a planter’s wart for good, at home. seriously do not recommend unless you are REALLY VERY CAREFUL about it. the end goal is literally a hole in your foot, and duct tape gets you there more reliably than acid lmao
she originated the alot AND the “clean all the things!/clean ALL the things?” memes, and it feels like hardly anyone even knows about the blog hahahah
