I'm not sure if this pertains to beauty, but I figured this would be the best place to post it....
I recently found out about these Poof Drops, seems cool. I ordered a bottle to see if it really works. http://www.poofdrops.com/
^These are huge in Japan and multiple brands made their way over to Hawaii. We sent some to my Uncles as a joke gift and it turns out that they (and their wives) LOVE them and now swear by them. I even have an aunt who keeps a bottle in her purse with her.
You can get them for a lot cheaper, though. The only other brand I know of off the top of my head is One Drop. They're usually in a clear bottle with a light blue cap - should be available at your local drugstores.
