I like to keep my cleansing products to a minimum when traveling, so I just pack dry facial cloths like Olay Daily Facials, $10, a soft textured cloth that lathers up nicely when wet. (I find they’re more convenient than the pre-moistened variety.) The cloths remove makeup, cleanse and exfoliate my complexion without leaving any residue. My mascara wipes away easily but you may have trouble with some of the more stubborn waterproof brands. They only come off with an oil-based makeup remover. You might want to consider switching to a regular mascara because if you don’t wipe your lashes clean of a waterproof formula, they could dry and fall out.
