Ewww! What lives in your eyelashes?

Constipated mites that's what.

Ok, yes there are countless mites living in your eyelashes, eating your dead skin cells. Our bodies are full of strange and wonderful mites and bacteria, all coexisting happily with us. And who knows - maybe someone will bring out a "product" to feed and nourish these little fellas.
In case you're still going eeew at the very thought the good news is:

• they're only teeny tiny; 0.4mm big
• they can't poo. They have a mouth to chomp with, but no er exit.

Look I dunno. Maybe they die of constipation or something.
