I don't really know how it works because the sample I got was a tiny tube and at that time I was going through an acne crisis [lol] so I didn't get to find it as effective as it should be. I didn't like the scent of it because it smells like a house cleaning product that I'm familiar with. I thought it was going to have a softer scent like honey or something similar. The solution dries quickly when you put it in certain spots that needs treatment. I would try it again though.
