Watch Two Dudes Go To Extreme Lengths To Test Long-Lasting Lipstick

In the search to find the best long-lasting lipstick, many consumers seek trusted opinions from makeup artists, beauty bloggers and fellow lipstick enthusiasts.

Rhett and Link, co-hosts of the popular YouTube show Good Mythical Morning, are not two people you would group under that umbrella. But that doesn’t mean they aren’t willing to use their lips for science.

Prompted by a reader’s question, the duo sets out to determine which long-lasting lipstick is actually “kiss proof.” The segment, aptly titled “Let’s Find The Lip-Stickage With The Least Lip-Slippage,” pits Maybelline’s Super Stay 24 Hour lipcolor ($8.99) against Stila’s Stay All Day liquid lipstick ($24).

Their commitment to the cause knows no bounds as they simulate “date” conditions that include eating ribs, dunking their heads into the “ocean” during a romantic walk on the beach and awkwardly making out with two mannequin heads.

In the end, only one lipstick is accurately described as surviving the test “like vinyl siding.”
