I got this as a sample several months ago (a couple of ounces lasted me a while) and I'm about to buy the fullsize. I tend to break out on my forehead and chin and this is great at clearing it up. It takes a few days to a week of overnight use to get completely clear, but I noticed a difference even after the first night.
This may dry out your skin (particularly sensitive skin people) if you use it more than once a day, but it says so on the bottle and recommends starting with once a day. Also, dryness/tight skin feeling isn't noticeable until the next morning and goes away when you wash your face and moisturize.
Applying, it feels and smells like a lotion or moisturizer.
