In 1841, German anatomist Jacob Henle was examining earwax under a microscope when, much to his surprise, tiny, worm-like creatures came into view.

00:19

Soon after, scientists realized that these animals were, in fact, tiny arachnids.

00:26

And now we know they belong to a group of mites, which scientists named Demodex, that contains more than 100 different species that live in and around mammals’ hair follicles.

00:39

Two of these species— Demodex folliculorum and brevis— specifically inhabit human follicles.

00:47

And not just some people’s. Nearly everyone is thought to host mites from at least one of these two Demodex species.

00:56

One person’s face might harbor hundreds or even thousands of individual mites.

01:02

So, yes: on any given day, microscopic arachnids are probably eating, mating, and laying eggs inside your pores.
