Review (2/5): Of the three I have tried this was the worst
I tried a couple other charcoal peel off masks before this that were MUCH much easier to use, both a bit more expensive but neither crazy so. Luckily I had no issues with the bottle splitting like some others reported. Here is what I did not like about the product.
Issue #1: This one didn't peel off in nice big patches more like you had to chip away at it which was messy time consuming and harsher on my face than it needed to be.
Issue#2: It also was ineffective, it didn't unclog anything. At most it removed a top layer of dead skin making my skin feel softer (and dryer), but after rechecking my pores with a magnifying mirror (if you want to hate yourself buy one and then freak out at your skin, lol) there was no real difference. The before and after of my pores under the mirror were nearly identical.
So all that work and annoyed skin for nothing. Mostly though I was just aggravated that it came apart in a million little shreds rather than actually just peel off my skin. That's the best part, booooo.
