I had a similar product from Burt's Bees that was awesome but the roller ball got really gunky, and contaminated the rest of the product. It was really disappointing because the product itself worked great.
I figured I would give another roller ball a try, and was glad I had some extra points laying around to purchase this. Had I spent my own money I would have been mad. This product does nothing. In fact, if you're a pimple you probably love it because every time I have applied it to a pimple, it gets bigger and angrier. Safe yourself the hassle and don't buy this. It's like Miracle Grow for zits.
