We've all had times when we wake up a day before a big event and lo and behold, a pimple. Clean&Clear's Advantage Acne Spot treatment offers a literal overnight cure for unexpected breakouts if used correctly.
In my experience, this stuff works! There's a slight tingy sensation when you first apply it, but it's pretty much expected of most acne medications. I usually put this on overnight when I rarely have breakouts. It reduces the redness most often to the point where it's easily covered by powder or concealer. It doesn't eliminate pimples overnight, however, but it does shrink them down.
When using this, I also noticed the effect was better when I first started using it. The effect of the medicine eventually wound down slightly over time, but it still works. Overall, I recommend this in conjuction with other acne medicine most. :)
