So I'll start by pointing out that this is a perfectly fine, serviceable product. It's supposed to exfoliate your lips, and it more or less does. It's basically just chunky brown sugar suspended in a emollient/waxy base. Like gritty lip balm.
But I see this pin all the time and for some reason it drives me crazy.
It's the caption that gets me, and it's always the same. I need to straighten things out here: don't buy this to use overnight. What are you going to do with it overnight? It makes no sense. When you rub this stuff on your lips, it leaves behind a bunch of grains of sugar and some moisturizing stuff. You can massage it around some more to exfoliate better, but then you still have chunks on your face that you have to wipe off. I guess you could then leave the remaining balm behind overnight and that might do something, but that's the case with any lip balm. Personally, I like to add some extra moisturizer to my lips, because the sugary taste of this stuff makes me want to lick my lips, and that's not good for them.
I know, I'm being too picky. Anyway, it works okay. I still usually have some big flaky bits on my lips after I use it, but then I always do, no matter what I try to do about that. I find that a little olive oil or honey with brown sugar mixed into it works better as a lip exfoliator, because the pieces of sugar in the e.l.f. stick are pretty big and sparse so they're not as efficient for scrubbing. They're pretty rough, too. The advantage of this stick is that it's more portable and (slightly) less messy than a homemade concoction.
So it's fine. It's convenient and there's nothing wrong with it. I wouldn't buy it again, but for $3 it's pretty cheap and certainly a better option than some ridiculous fucking $25 lip scrub. But $3 worth of oil and sugar would go a lot further and work a bit better.
