I don't get many pimples these days (it was a different story in my teens!), but when I do, I always whip out this gel as soon as I see the pimple. It's a great little tube with good control over how much product is dispensed. You only need a really small amount so it's good to be able to be precise. It has a strong smell, but I'm ok with that in a spot treatment.
I find that this gel really helps to clear the pimple up fast. The gel dries clear so you can put other creams or makeup on top (although I generally find it good not to smother a pimple - air is good for it too).
The only downside to this cream is that if you use it too much the area can become a bit dry.
