Sacheu is the pinnacle example of “TikTok viral”. Founded in 2020 by beauty creator Sarah Cheung, the brand first made waves with stainless-steel gua shas before pivoting into makeup built around its signature STAY-N technology—peel-off lip stains designed to last all day. The real breakthrough, however, came when Billie Eilish filmed a casual GRWM video for her TikTok channel, lining her lips with Sacheu’s Peel ’n’ Stay Lip Liner Stain in nOOHde, a rosy-brown nude. Within hours, TikTok had turned it into a must-have, and soon one liner was reportedly selling every six seconds on TikTok Shop.
