I don't think most consumers know that their lipstic or eyeshadow contains microplastics.

I'd wager that they either know or don't want to know...

I didn’t. Had I considered it I would have assumed that at least in the US regulations would prohibit its inclusion.

Whatever the product may be, it sparkles, so it can’t be much of a secret.

Does this product contain glitter? https://3.bp.blogspot.com/-djINoSKP6FQ/T_2q9sPNqZI/AAAAAAAAA...

Probably, no. My guess is it contains small metal particles. But if I wanted to determine that, I wouldn’t look at a photo. I would read the ingredients.

A lot of cosmetics straight up contain phthalates as an intentionally added ingredient.
