Why Are There Animals on My Face?!

The video discusses Demedex mites, microscopic arachnids living on human skin, particularly around hair follicles and oil glands. Two species, Demedex folliculorum and Demedex brevis, are common but not present at birth. They are transmitted through close contact, often from parents. While generally harmless, an overabundance can contribute to skin conditions like eczema and rosacea. Mites do not defecate during their lifetime, and their waste may cause skin irritation. Despite this, they are a natural part of human biology, similar to gut bacteria.
