Trial-size beauty products are the tapas of the product world. For we skincare swingers, they make it so that each day is a surprise. Neon lipstick? Luxury cleavage oil? Eye-squint-eliminating adhesive mask? Check, check and check. They’re a way to keep things new, fresh and full of excitement. Even better, they’re a way to overcome the conundrum of the three-ounce TSA restriction. For years, I would buy miniature bottles at the drug store, then gingerly squeeze favorite shampoos into them, hoping more made it into the bottle than dribbled down the outside. Heaven help me if I didn’t label the bottles — there was no telling what lurked inside the opaque fuchsia squeeze tubes.
