And why shouldn't it? After all, the trend in beauty products these days seems to be the more disgusting, the better. And our No. 1 pick is no exception ...

Leech

No. 1: Leeches

Remember how in the "olden days" doctors used to put leeches all over someone's skin as a bona fide medical procedure? Well, apparently, the practice is not as outdated as most of us thought.

In fact, actress Demi Moore recently boasted on the "Late Show with David Letterman" about her lovely experience with "leech therapy" during a trip to Austria. According to Moore, "They have a little enzyme that when they are biting down in you it gets released in your blood and generally you bleed for quite a bit -- and your health is optimized."

Yeah, excessive bleeding has always been known for optimizing health.

Of course it is difficult to deny that Moore looks healthy, vibrant and much younger than her years, so maybe she is onto something here. But at what price? Certainly one that is way too high for most of us, based on the "ewwww" factor alone.
