aactually no. there is a compound used to make mascara that also happens to be found in bat poop, but that doesn't mean that is what they use. this compound is also found in fish scales. I believe it was called guano? i think. I learned about it in my biology class.

so yeah, NO BAT POOP IN MODERN MASCARAS.

Yes, I think some brands use that in their mascaras. I couldn't tell you which ones though, but I'd imagine higher end ones would be the ones to do that. It's not really a big deal though... I mean, honey is bee puke and people still eat it, and lots of dyes are made from insect juice, but people still use them.

Yessss. It uses in the more expensive brands. Like the department store brands.

Not in modern cosmetics. Guanine which can be derived from guano is used, but is now produced synthetically.

In your grandmother's day, there were many surprising ingredients in cosmetics (like guano), including mercury in lipstick and bird guano in eye shadow.

It depends on the mascara

yes but thats only from natural mascara the usual mascar's r made from lanolin, eucalyptus oil, mineral oil, castor oil, linseed oil, or oil of turpentine,Sesame oil,carnauba wax, beeswax, and paraffin, among others.

its true. but of course they sanitize it and stuff before they put it in the mascara

Yes, the more expensive brands use it.

omg.. seriously?! i never actually knew this lmao.. how scary!
