Latisse

I was just watching the Drs and they were talking about a prescription eyelash extender called Latisse. It's a liquid that you apply right above the lashline like eyeliner. It's supposed to make your lashes thicker and longer. Has anyone else heard of this or used it?
I have the worst thin and short lashes! I'm wondering if it's too good to be true or if it really works. If it does I'm sooo getting it!
