I like this stuff! My blemishes are usually just tiny irritated white heads or bumps with nothing in them. If I put this on at night, things are much calmer in the morning. It even seems to have a minimizing effect on the few deep painful cystic guys I get, so they end up fading away rather than coming to the surface full of rage. And so far I haven't had any irritation (and I have very sensitive skin). I put this on after my last oil stage, after things have dried down a bit. I feel like that works best since I use it as a spot treatment, and putting it on under other stuff seems like it would just spread it around.
