The Birchbox Beauty Hacks column aims to merge cosmetic queries with science. Specific studies and gathered data are applied here in an effort to get down to key beauty questions, delivering sound and informative advice to readers.

Among the questions asked by the Birchbox team is how many swipes can a single lipstick product put out? To begin, the team took the size of women's lips as a starting point, measuring approximately 55mm in length on average.

Four different tubes of lipstick were then tested, striping them incessantly for hours on sheets of paper. At the sum of the study, it was found that most products lasted for 293 swipes, durable output by most measures.
