"My skin is very sensitive and I blush easily. I have dermatographia, a condition in which one’s immune system releases excessive amounts of histamine, causing capillaries to dilate and welts to appear (lasting about thirty minutes) when the hypersensitive skin’s surface is lightly scratched. This allows me to painlessly draw on my skin with just enough time to photograph the results."
Beauty is especially skin deep if you’re artist Ariana Page Russell. She has dermatographia, a condition in which lightly scratching your skin causes raised, red lines where you've scratched. It affects roughly 5 percent of the population, but Ms. Russell is the only one who has turned her puffy, ruddy, sensitive skin into elaborately patterned high art.
