I was so underwhelmed with this bar. I loved the concept of one simple ingredient in a bar that would be gentle enough to apply as a daily mask, and all of the rave reviews on it gave me high hopes. But alas. It did nothing to reduce inflammation or otherwise calm redness. I don't break out much so maybe I would have noticed more of a difference if I had acne, but I was hoping this would improve the redness of my skin and maybe diminish the noticeability of my pores, but it really did nothing to my complexion. I have dry skin and was worried this would dry me out, as it is a clay, but it didn't. For me, that was the one pro of it, but if you have oily skin and are hoping it will reduce oiliness, you may be disappointed.
There are quite a few products that I've used in which I've noticed a discrepancy between what should happen, scientifically, and how my skin actually responds. I think I just have very fickle and sensitive skin. I'm torn on whether to recommend it to reduce oiliness, because this should work for that. If you have oily skin and that's the main reason you're looking into this, I would give it a chance. That is the only case in which I would recommend it.
Quite a few users have commented on it being a pain to apply. I'm a results kind of girl, so if a product is effective, I can deal with messy application, inconvenient packaging, that kind of thing. But if you like the ease of squeezing a mask out of a tube, you may be annoyed with having to apply it from a bar. It does get messy and it does feel like you're wasting a lot of product. Keep in mind that you want the bar to dry out during the day. I wouldn't leave this in the shower because it won't dry, and the clay will continue to drip, gradually wasting a lot of product.
I let this sit on my skin for about 10 minutes every evening for a couple weeks before I gave up on it. Yes, I know that's not all that long for a skin treatment, but considering this has only one ingredient whose properties should go into effect upon contact with the skin, I felt that two weeks was a long enough trial run. It would be different if this was a retinol product that I was using for hyperpigmentation, but this is a lot more basic than that and I hadn't noticed any difference.
I'm giving it two lippies because it had no adverse effect on my skin. But otherwise this was meh for me and I returned it.
