The microorganisms that use the human body as a host often have an extremely bizarre appearance, which scares a lot of people. A good example is this, which is called Demodex.

It lives in an area of the body that you probably don’t even expect, namely: eyebrows and eyelashes. It feeds on hair follicles and, although it looks like a dangerous being, it is very harmless.

In rare cases, the microorganism can cause inflammation and irritation, this happens especially when the person hosting it has a weakened immune system.
