I have been wearing Lip Smackers on my lips since high school fourteen years ago.  I always feel silly in a way, and I try to find a replacement in a more "mature" package, but I always come back to Lip Smackers.  My two favorites are in the Skittles line, banana and strawberry.  These seem more moist than the traditional Lip Smackers, and the moisture lasts longer, and it give my lips a pretty sheen, I don't even wear lipstick or tint.  They're very cheap, and I can buy them in bulk on Ebay for a great price also.  I highly recommend Lip Smackers.
