When I first got this product I LOVED it. After a few weeks I realized although it was clearing up my acne very fast (at night I had a blemish, and the next morning the swelling was down and there was only a scar left), it dried out my skin terribly. I found it a little difficult to use as it seemed all the liquid would come out, but the pasty pink stuff was usually separated from it, and the bottle says you shouldn't shake or try to mix it. After about a month I ended up with a jar full of paste, and no liquid. Now, if I need to use it, I'll stick a q-tip into the jar to get the product out, but it is not the way it is meant to be used. Although I love how quickly it reduced my blemishes, I did not like how severely it dried out my skin. Instead of concealing a pimple in the morning, I would literally have a face full of peeling dry skin. I'm very torn about this. I probably wouldn't buy it again, but it did work great for what it is meant to do.
I purchased this to help with hormonal breakouts, I apply a small amount with a Q-tip and leave on overnight, in the morning it significantly reduces swelling, size, and redness. Only a small amount is needed, so this bottle will last a long time. It has that sulfur smell but I don't find it overpowering at all. I will definitely be buying again.
