We’ve done our makeup in plenty of questionable environments: while sitting on a towel at the beach, in an airport bathroom stall, and inside a moving car. Thankfully, we always pack our bags strategically, knowing that a makeup moment can arise any time and any place. To prepare, we usually rely on the help of dual-purpose makeup sticks, travel-size products and portable makeup brushes. Travel makeup brushes are surprisingly helpful, take up very little room in your bag, and will calm the nerves of every makeup lover who gets antsy when separated from their everyday makeup brushes. Ahead, we’re rounding up some of our favorite portable brushes, featuring retractable options for the beauty guru with the bag that’s bursting at the seams, the sleek pink set your friends will ask to do their own touch-ups with, and the palm brush for seamless, your-skin-but-better coverage.
