Before he was a billionaire, Kim Jung-woong was a wholesaler shuttling Korean cosmetics to buyers across the border in China, learning firsthand how hungry that market was for K-beauty and how thin the supply could be. When he launched his own sheet-mask line in 2016, the breakthrough came not from a department-store rollout but from Alibaba's Taobao, where the masks went viral and Chinese resellers known as daigou began clearing them out by the case to ferry home at a markup. That arbitrage, accessible prices in Korea versus inflated imported prices in China, turned volume into a torrent.

The scale that followed was staggering enough to make headlines. Forbes Asia and South China Morning Post chronicled how the masks built a personal fortune estimated above a billion dollars in roughly two years, and Goldman Sachs took a five-percent stake reportedly worth tens of millions, an unusual vote of institutional confidence in a brand best known for foil pouches.

The product strategy was theatrical by design. The flagship masks were named for premium-sounding actives, bird's nest, golden caviar, jellyfish, pink snail, each promising an exotic indulgence in a single-use sheet, sold in glossy packaging that punched well above its price point. From there the catalog widened into ampoules, creams, cleansers and sun care and softer botanical lines, but the mask remained both the signature and the cash engine, especially across China and wider Asia.

The candid framing is that this is a triumph of distribution and consumer psychology rather than dermatological science. The headline ingredients function more as storytelling hooks than clinically dosed treatments, which means the smart move is to read the actual ingredient list rather than the name on the pouch, and judge each mask as the affordable, pleasant hydration vehicle it usually is.
