A group of teenage girls was caught on camera allegedly attempting to use dark makeup testers for blackface inside a Boston Sephora store. A viral TikTok video showed two girls covering their faces with cosmetics meant for darker skin tones. The Sephora staffer condemned the act as "incredibly offensive" and asked them to leave, expressing disappointment. The adult chaperone and the girls later confronted the person who filmed the incident, asking to delete the video. Sephora issued a statement condemning the behavior and emphasizing that such actions are not tolerated. The incident occurred amid a trend of disruptive behavior by young customers in beauty stores known as the "Sephora kids" craze on TikTok.
