Face Off is a American Sci Fi reality tv game show
I do not know much about it.  What is it about?
These prosthetic makeup artists compete with each other to create prosthesis like seen in horror movies
That is interesting.  Has the show been on a long time?
Well Face Off has been on sinnce Jan  2011 on Syfy channel
Is the show use judges, or is it voted on by the fans?
each episode presents a challenge and the results are reviewed by a panel of judges
I really think those make up guys are talented.  What they can do on shows like the Walking Dead are amazing
