Wait, you’re telling me that these are crawling around on my face right now?’


The demodex brevis (also known as 螨虫) are microscopic mites that live in the skin.

These 0.015 – 0.2mm mites are ecto-parasites – they feed off sebum from oil glands in the skin.

Who has these mites? Do I have them?

Skin cell scrapings suggest that roughly 10-25% of adults have demodex mites. However, DNA sampling has lead some researches to theorize that demodex mites can be found on virtually every human.[1]

Are demodex skin mites harmful?

When present in large quantities, demodex mites are associated with the following:

  • Acne

  • Ezcema

  • Rosacea

  • Rough skin

  • Burning sensation in skin

  • Red, itchy, sensitive, or irritated skin
