Men, here is a way to keep your face feeling and looking good without going afoul of the TSA airplane carry on rules: The Nivea for Men 4 step starter set. The four items come already packed in a Ziploc bag and all are under 3 ounces. One purchase at the drug store and you're off.
It's got shaving gel, after shave balm, face wash, and SPF 4 moisturizer to keep those crow's feet eye lines to a minimum. Everything you need for your face except a razor and lip balm.
True, this won't cover the cosmetics gamut, but throw in a sample size deodorant and toothpaste and you're good to go for the journey. You don't have to be a metrosexual to know that cold winters and desert dry airplanes will make you look older than you are if you don't take care of your skin. This kit from Nivea for Men makes it dead easy.
