Top model and Kardashian half-sister Kendall Jenner has been known to tout Estee Lauder’s Drop Dead Red shade of lipstick.
Jenner followers take note: the lipstick has ingredients that, according to health and beauty app Think Dirty, could be harmful. Think Dirty scans cosmetics labels and rates the lipstick a 7—or three points short of the dirtiest grade on a 1-to-10 scale. The putative culprit: polyethylene, a polymer commonly used in cosmetics that Think Dirty says could cause allergies in some people. (Estee Lauder Cos Inc. says polyethylene is not a known allergen.)
