I've only seen Syfy's Face Off a couple of time, but the episodes I've seen have been an interesting look at how Hollywood's makeup artist do their job.  The challenges are usually intriguing and the final product is usually amazing.

This season the series is bringing back previous champions to mentor the new recruits.  You can watch a promo here and be sure to check out the season premiere one week from tonight, January 13 at 9/8c on Syfy.
