Don't put Vaseline on your lips. Vaseline is made from the goop that comes from oil drills (petroleum jelly, remember?), so it's something you don't want too close to your mouth because you'll ingest little bits each day. Instead, use cocoa butter or Burt's Bees Balm to moisten up dry lips (they use beeswax -- good for bees, ok for you).
