Your skin could literally be crawling right now, or at least the mites in them could.

You may have heard of the half a millimeter long, face mites that are invisible to the naked human eye, but did you know that we might all be infested?

A new study of 253 people over the age of 18 found that 100% of sampled people had Demodex mite DNA on their faces suggesting that these semi-transparent, 8-legged mites could be universal. Yikes.

The human face houses two types of these mites. The first, the Demodex brevis inhabits the sebaceous glands (oil glands)—one to a few per glad. The other, better-known type is Demodex folliculorum, which enjoy their stay on hair follicles like eyelashes and eyebrows, right above the oil glands, where they ingest cell contents.

Additionally, the study found that mites varied genetically depending on where they are from; for example, China’s skin mites were distinguished from those from the Americas, thus being useful for tracing human populations and their migrations.

Hate to break it to you, but you and your body aren’t alone. Know more.
