I'm going to preface this and say to be cautious....make sure you're getting a LEGITIMATE real product, and not a fake. This stuff is AMAZING. One thing I've learned about MB products, is that you have to let go of your preconceived notions of words like "lotion." They're taking the pharmacological terminology here: "a liquid, usually aqueous or sometimes alcoholic preparation containing insoluble material in the form of a suspension or emulsion." MB "lotions" are often very thin liquid. This is no different. Shake it up, and it's the consistency of skim milk. The sulfur is the main active ingredient here, and it works well, but is very drying. I have oily skin, not a huge issue for me, and I use it for spot treatment. I'm suffering an awful hormonal breakout of some deep cysts now, and I put this on last night. I'm not going to tell you they've miraculously disappeared overnight, but they are SIGNIFICANTLY better this morning! One that was smaller was very nearly gone this morning. I dab this stuff on with (clean) fingers. It dries on fast, so I pat it on until I see a thin hazy white patch over where I want it. I do this after all of my other skin care steps....just at the end, and leave it be overnight. It's been a lifesaver, in addition to their drying lotion. It's TOTALLY worth spending a couple of bucks on (even original price, to make SURE you get a genuine product). It lasts a LONG time. I am not even half way through this bottle after a year and a half. Keep in mind, this is one step, one tool, it's not going to create miracles if the rest of your skin care routine is crap.
