Works so well. I use it once a day and the little jar lasts me for a long time, so the price is not bad at all! Helps to dry out current pimples and prevent some before they even pop up. I use this in the morning in my T-Zone and it works all day without drying my skin out.
I have hormonal cystic acne and I was really hoping it would work, since regular acne drying products don't work. The first time I tried it, I had a cystic acne that was more mature (had been there for a couple of days already) on my skin, so it didn't make much difference. Then I started applying as soon as I started feeling the bump growing. Most times, it didn't disappear overnight, but it did help control the size so it dried faster and never got huge. So if you're looking for a miracle product, this is not it.
A problem with this product, also, is that it doesn't really dry on the skin (I've tried applying hours before going to bed), so expect it to transfer to your pillowcase. The smell is also not great, but it goes away.
I haven't used this product much so far, but so far I like it! It was not too expensive and is easy to apply. I apply overnight, and when I wake up the spots seem to be dryer. Great for acne.
