My eyeliner got wet and won't work. Is there a way to fix it?

It's one of those fancy clinique eyeliner pencils (not liquid liner). It got wet about a week ago when I dropped it in the sink. I tried wiping it off with a tissue. It's dry now, but ever since it got wet last week it won't apply evenly or smoothly anymore. Barely any color goes on. Do I have to throw it out? I'm going to a wedding this weekend and don't have time to get to a dept store to buy a new one...
