No idea. But I'm trying anyway. 

I did a few searches to see what sorts of things would quicken my mustache pace (B vitamins, getting lots of sleep, buying more socks), and one of the articles mentioned that eucalyptus oil (if applied to your face) would make it grow faster, bigger, better, stronger. 

I put some on last night before bed and awoke to... nothing. And upon application, I recoiled from the smell (which is a rare blend of smelly feet and yummy mint). I figure I'll keep putting it on each night for a week and see if growth hastens on the sides of my mouth (where I'm patchier).

I should also point out that I picked Pharmaca's version without consulting the internets. It was $4, dude.
