This foundation from Hourglass is unique: Not only does it cover up blemishes and mattify oily skin, it can actually improve breakouts.

The product initially launched last year, but due to an issue with the pump mechanism, Hourglass was forced to remove the foundation from shelves. According to a representative, the company was inundated with emails and phone calls from people begging them to bring it back, claiming the foundation had cleared up their acne and minimized scarring. The brand complied and went one step further, conducting clinical tests on these zit-zapping claims. The trials are ongoing and the brand is still awaiting final results, but we think the outpouring of customer love speaks volumes about this one.

Hourglass Immaculate Liquid Powder Foundation, $55, available at Sephora.
