Beautiful and part of our health! If we destroy them, then we'll have many skin diseases! The same applies to all the bacteria living inside our intestine.
Don't freak out, but you probably have a few dozen arachnids grinding up on the tiny shafts of hair lodged inside your face, quietly gorging themselves on your natural oils.
OK, you can freak out if you want. But there's nothing wrong with you. These tick-like arachnids are known as face mites (in the genus Demodex) and, according to a skin-tingling new video created by the folks at KQED San Francisco, they live a peaceful life buried in the facial pores of most human adults. (The mites are not found on babies, and they are thought to be transmitted through motherly contact.)
These creepy-crawlies are eight-legged, mostly transparent and microscopic in size, measuring about 0.01 inches (0.3 millimeters) apiece, according to an NPR article accompanying the new video. They live near the roots of facial hair follicles on both men and women, hidden away inside your pores.
