Ariana Page Russell, suffers from “dermatographia”. That is: she scratches her skin until it leaves swollen, red imprints on her body. She is using this rare condition of hers as a form of art. She draws on her skin as you can see above, making beautiful designs. She enjoys it very much that she is not looking for a cure.
For me, I find it pretty weird. I am amazed by the art on her skin and its a bit weird since a new and unusual thing for me. I am very attracted to such news; it just gives something new to think about.
I would recommend you to read this article. Very interesting indeed and you can decide whether this is weird or pretty or both.
