On your face, right now, there are tiny bugs that are closely related to spiders, living, and possibly mating, in the pores of your face. For years, these tiny bugs were considered harmless passengers that were riding the natural ecosystem that exists on your face. It wasn't until 2012, that scientists started to believe that these tiny bugs could be the cause of an ancient skin disease!
The disease, Rosacea, effects around 5 and 20 percent of people worldwide. The disease was nicknamed the "curse of the Celts" as it is often found in people who have very fair skin. A commonly thought cause of the disease was excessive drinking, and while it can make Rosacea more noticeable, it isn't the exact cause.
Kevin Kavangh of the National University of Ireland thinks he discovered the cause. Tiny mites, live in the pores of your facial skin. They love the hair follicles of eyebrows and eyelashes, and the areas around the noise, forehead, and cheeks. The mites it facial oil, and basically colonise your face at puberty! These little insects are called Demodex!
