Effective for inflammatory acne. For localized use. The pus hardens and peels off like a wound 2-3 days later. But it seems to be discontinued, so I'm using it sparingly...

The applied area becomes dry. Those sensitive to sulfur compounds should not use it (my husband had side effects). I'm using it well.

I've been using it for a long time. My skin is generally good, but around my period, I get one or two large, inflamed pimples. As I've gotten older, it takes about a month for them to subside, and I end up with some discoloration. When a pimple is about to surface, if I apply the product well, it comes up within two days and then goes away again. If I keep applying it for a day or two after that, my menstrual cycle clears up and the pimple disappears. The effects are immediate. It also seems to have a blemish-reducing effect on existing pimples, so I dab it on with a cotton swab.

The smell is somehow, I don't know, it's a strong and frightening ointment smell, like it's going to completely peel off my skin. When I apply it to my skin, it feels like it's burning and heating up. I'm scared, so I only apply a little bit at a time, but looking at the ingredients now, it's not as serious as I thought.

Many reviews say that this product causes flaking after use, and when I apply it, a thin, plastic-like layer does peel off as it dries and hardens. I suppose that's part of the healing process? I've found that if I apply it thinly, especially at night on just the problem spots, it dries quickly without any peeling issues, and I can apply makeup over it in the morning. The thick application seems to be what causes that flaking. It's amazing for spot treatment, but don't use it around your eyes - it's way too irritating. I stopped using it for a while because the smell was so off-putting, but then my acne flared up again, so I started using it regularly. Even after a break, it still works really well for me.
