The package says “gone by tomorrow” but that’s unfortunately not the case. I feel like the spot eraser is helping a little though. You have to apply the solution to the spots/blemishes you want to erase and leave it on overnight. The solution dries immediately when applied on the skin. You don’t really feel it on your skin either. I find it a little annoying, though, because you can’t apply a moisturizer on the area where you applied the spot eraser on your face.
