Fiona Cai is an internet host from Nanchang, China, who livestreams the nation’s pop songs to several thousand social-media followers. She’s 28 but spends about 1,000 yuan ($155) each month for a skin booster injection.
“It can help minimize pores and whiten my skin, and I feel my makeup works better,” she said in an interview. She first tried the treatment a year ago. “But my body will process it in a few weeks, so I have to keep it up every month.”
