In a 15-second TikTok clip that has racked up millions of views, Kylie Jenner glides a sleek silver device across her face, swearing by its ability to help skin absorb serums more effectively. Dubbed the Booster Pro, the gadget’s video has gone viral — and with it, the fortunes of its maker APR Corp., a once-obscure Seoul-based startup now at the center of the K-beauty boom.

Behind the firm is 36-year-old Kim Byung Hoon, a tech entrepreneur-turned-beauty mogul whose company has made him South Korea’s newest billionaire. His 31% stake in APR is now worth about $1.3 billion, according to the Bloomberg Billionaires Index, after the firm’s shares soared 200% this year.
