Kylie Jenner’s European promotional tour for her beauty brand, Kylie Cosmetics, got off to a rocky start last week.On Instagram, the influencer posted photos of herself, dressed in a white lab coat and peering into a vat and weighing a beaker full of shimmering loose powder. ‘In the lab creating new magic for you guys,’ the caption read. Some of her 365 million followers quickly pointed out she wasn’t wearing a mask, gloves or a hairnet. Those would have been necessary in a facility manufacturing cosmetics for commercial use, but not in a testing lab, a person familiar with the matter said.
