I started using this when I started breaking out frequently. It's smells like medicine but applies well. It doesn't foam up but only a little is needed. I felt as though it cleaned out my pores and did a great job at removing left over makeup.
It calmed my breakouts and my skin felt smoother and refreshed after use. This didn;t necessarily prevent breakouts/acne but it did help control it. My usually oily skin was more manageable. My skin didn't get so oily throughout the day.
This does dry out the skin (just a little bit) so I suggest using a moisturiser afterwards.
