Through many years of dermatological visits, I've had my share of sulfur treatments. And while they aren't the best smell, I like the way they work. It definitely dries out your skin, but paired with a good moisturizer (I use Kate's oil-free), it helps dry up breakouts and seems to refresh my skin. Because it dries pink, it doesn't really work for me to apply multiple times a day, so I just this before bed. Be careful to follow the instructions and apply with a cotton swab to get the most out of this product.
I was really excited to try this but it just didn't dry up the acne like I thought it would. It may help a little, that is why I gave it 3 stars, but I wouldn't pay this much money when a simple acne cream from the drugstore would do almost as well. I really wanted this to work, I love everything else from Kate Somerville.
I use this whenever I feel a pimple starting to develop. I just put it on after my normal night time routine and it really makes a difference! Most of the time the pimple goes away after just using it the once!
