Your feet are probably nasty.
That’s a pretty safe (and gross) bet.
You don’t even have to be one of these hardcore Paleo, bearded caveman, walks-barefoot-everywhere types either. Your feet are on the bottom of your body. You walk around on them all day.
By now you’ve surely seen a beauty blogger talking about these or possibly some content aggregator posted a bunch of screenshots of tweets they found on social media about it.
The process is super fun for everyone who likes peeling the skin off from a sunburn, doing that thing where you put glue on your hand and let it dry so you can peel it off, or any other weird shit like that.
If that’s not really your thing, then you can post pics of your foot exfoliation to gross out your friends.
