The best way to clear a pimple is to kill the bacteria and soothe it, and best way to do that is by using all natural ingredients. Nature provides us with amazing herbs and essential oils that safely soothe and heal those annoying zits, so there's no reason to look towards harsh chemicals or dangerous ingredients to solve your skin issues.
Next time you have a pimple, try a more natural remedy like the one from Desert Essence. I got it at Whole Foods and it really does the trick. It isn't completely gone the very next day, but, my breakout has calmed down and are definitely fading.
