This is one of the greatest products I have ever come across.  It smells like tea tree oil, but nothing too overpowering.  The consistency is very watery but sometimes might leave my skin a little sticky.  This doesn't matter, however, because its ability to zap my zits is incredible.  I have quite oily, acne prone skin so this has been awesome for cutting down on my oiliness.  Acne size is considerably reduced overnight and helps prevent scarring.  I'll definitely repurchase this when I'm out!
