I'm traveling this week to the Sciton Laser User Summit, and then to see the fam for Thanksgiving, so I've got travel sizes on the brain. Here's a neat DIY project (yes, you need a heat sealer, but I might be drinking the Kool-Aid on this one: I could be buying one soon!) to bring all of your great products with you! This seems like a great way to travel with cleansers and SPF's. I would still consider exposure to oxygen once the products come out of their original packaging, so be sure to use them up within a week for best results.
