If you're plagued with oily skin that always ends up looking shiny no matter what you do, the cure may be minty-fresh. It's said that a mask with milk of magnesia can suck the oil out of your pores. Weird, definitely. But is it safe?

Says Dr. Sobel: "Milk of magnesia has hydroxide of magnesia as an ingredient, which absorbs oil and causes the skin to tighten. You can apply it all over the face, or just on blemishes as a spot treatment." Simply apply to skin, let dry for 15 or 20 minutes, rinse, and follow with a light moisturizer for super-smooth, matte skin. Gross, but cool, no?
