The Full Story A disgusting photo of an injured hand has been floating around internet recently — and it’s the kind of image you can’t get out of your head. But what freaked us out were the headlines we’ve seen with it: What Parasite Caused This? You Don’t Want to Catch This! Did some creepy critter really cause this skin condition? A search on the image reveals that it’s from a YouTube video called “Trypophobia Hand Tutorial” from QUEENKINGSFX. They show how to make this bubbly skin on your own body using Mehron Spirit Gum, Ben Nye Nose & Scar Wax, Argan oil and some basic home tools. So, in terms of whether or not there is a parasite that causes this, the answer is — No.
