Just mineral or ground rocks work just as well. I hate my wife’s soft face scrub, i need that shit that feels like I’m scrubbing my face with sandpaper, to exfoliate well. They sell one that has ground up lava rock, i love that shit, and it makes me wonder why anyone ever thought plastic bits was a good idea

    I feel like it's just capitalism doing a capitalism. People are self-conscious about their skin, so you can sell them all kinds of crap.
    Even a basic washcloth does a decent job with exfoliating, if you use it regularly. Rub your face dry with a scruffy towel, if you need more than that.

    But of course, there's hardly any money to be made with reasonably priced products, so you won't see TV ads for them.

    My ex would use St. Ives "Apricot Exfoliant" or something, which has powdered apricot pits and walnut shells. Those are waste products that I wouldn't expect to cause problems but who knows.

    I wouldn’t be surprised if they cause issues in pipes. I work in building maintenance and when sand collects in a horizontal drain it causes issues. Kitty litter is the worst because it turns to cement inside the pipes. But over time the beauty products add up im sure

    Well, rocks in toothpaste would be very bad because they'd be harder than your teeth.

    Harder? No. Enamel is harder than steel. It is more brittle though so don't go chewing rocks.

    Tooth enamel is ~5 on mohs scale. Quartz, the most common kinda rock (afaik), is ~7. You're correct that enamel is harder than steel though, since it's ~4? Disclaimer: all of these numbers are from a quick google search.

    Fun fact, this is why we know ancient people used to make bread - the way they separated wheat from the chuff included dropping it on the ground, which led to sand being in the bread and consequently destroying their teeth over a lifetime of eating it.
