Face Mite (or Eyelash Mite)
Scientific Name: Demodex folliculorum
Order & Family: Order: Trombidiformes; Family: Demodicidae
Size: 0.3–0.4 mm in length (microscopic)

Natural Habitat
Human hair follicles and sebaceous (oil) glands, particularly on the face, forehead, nose, and eyelids.
Diet & Feeding
Skin cells, sebum (skin oil), and hormones found within the hair follicles.
Behavior Patterns
They are nocturnal, emerging from follicles at night to move across the skin surface to find mates and lay eggs. They lack an anus and accumulate waste in their bodies until they die.
Risks & Benefits
Generally harmless commensals that may help remove dead skin cells. However, overpopulation is associated with skin conditions like rosacea, blepharitis (eyelid inflammation), and demodicosis.
