Tip 6: Don't Pack Your Entire Medicine Cabinet
If you can survive a few days without using your usual products, consider leaving them at home. If where you're going has shampoo, lotions, and body washes, definitely ditch them as they take up valuable space (one helpful tip is to go to your favorite skin-care and makeup counters and ask for samples). Only bring your essential products that do double duty. Smudge-able eyeliners, cheek and lip stains, and lotions that work for both your face and body. Pack all liquids in gels in a plastic bag and place it in your makeup bag. Chances are, the TSA won't stop you for little bottles (as long as they're undef 3 fl. oz!), but if they're all in a small bag, it'll be easy to whip them out if there's an issue.
