I don't understand how this works, but it works! You dip a cotton bud into the bottle, right to the bottom, where all the pink liquid is resting. Then the cotton bud is dragged upwards through the liquid. Dab the cotton bud on to your spot, at night, and go to sleep. Your spot will disappear in the morning! It's insane.
Best product for clearing up the odd pimple or two.
There are cheaper acne treatments out there, but I have always turned to this brand. Anyway, the bottle is quite huge and I only use small little dots on my pimples. Handy if you tend to have random breakouts.
