Facelights are so 2008. Trust.
With the way the lighting in SL works now and the way skins have evolved since 2008, you don't need a facelight. Not to mention how annoying they are to everyone else around you. The glare follows you around like you are wearing a searchlight on your face. You are washing out everything (including your potentially lovely self) for everyone around you - which is incredibly bothersome for others, who then derender you. You are so pretty when you are derendered - all invisible and see-through and transparent!
For those who think facelights make you look pretty here is a little demonstration:

Not really. Polar bears *hate* marshmallows. But this is what a facelight wearer looks like to everyone around them! This photo was taken with a facelight made up of only 3 lights! I've seen some facelight addicts rez in with an entire solar system of lights around their heads.
Pretty girls don't need to wear facelights. (See what I did there? I am throwing down the gauntlet!) Help make SL beautiful -- ditch the facelight.
