Kim So-hee and 3CE: A K-Beauty Case Study of Rising from a Dongdaemun Online Shop to L'Oréal's Acquisition

Origin

At the age of 22, Kim So-hee sourced clothes at Seoul's Dongdaemun wholesale market and started a clothing retail business via her website, stylenanda.com. At a time when South Korean online fashion retail was intensely competitive and homogeneous, she noticed that the makeup worn by models attracted more clicks than the clothes themselves. She began using self-made lip tints and eyeshadows for promotional purposes, which unexpectedly prompted buyers to ask where they could purchase them. Realizing that clothing margins were thin and cosmetics had high repurchase rates, she turned makeup from a supporting element into the main focus, gradually transforming her online clothing store into a cosmetics brand.

Milestones

Turning Points

• During the online fashion store era, noticing that models' lip colors attracted more attention than their clothes, she shifted makeup from a supporting role to the main focus.
• Early quality complaints and returns on private-label makeup forced Kim So-hee to shift toward in-house formulation rather than casual ODM manufacturing.
• In 2009, 3CE was officially spun off from Stylenanda's cosmetics line into an independent sub-brand, establishing a positioning of youthful and bold colors.
• In 2018, L'Oréal acquired a majority stake in Stylenanda for approximately 600 billion won, placing Kim So-hee among South Korea's wealthy female entrepreneurs.
• After integration into the corporate giant, the brand's responsiveness slowed down, the founder eventually stepped back, and in 2026 she launched a new entrepreneurial venture with the brand Situea.

Failures & Pitfalls

• The online fashion store hit a growth ceiling amid homogenized competition in Dongdaemun, resulting in razor-thin margins and strained cash flow.
• Early private-label lip tints and eyeshadows suffered from fading and allergic reaction complaints, forcing massive returns and a complete overhaul of formulas.
• After joining L'Oréal, 3CE was slow to adapt to new content channels such as Douyin and TikTok, losing consumer mindshare to domestic and competing brands.
• The founder's voice was diluted by the multinational corporation, leading her to gradually step back from operations, resulting in a prolonged hiatus and an inability to maintain the momentum of viral hits.

Competitors / Peers

In the same market segment, 3CE competes domestically in South Korea with Amorepacific's Peripera and Etude House. Both follow an affordable, youth-oriented makeup strategy focusing on lips and cheeks, but benefit from corporate backing with advantages in distribution and R&D. In the Chinese market, it faces domestic C-beauty brands such as Judydoll, Joocyee, and Perfect Diary, which rapidly scaled post-2018 through content-driven marketing on Douyin and Xiaohongshu—precisely during the window when 3CE's responsiveness slowed after its integration into L'Oréal. Globally in the mass-market cosmetics segment, Maybelline and NYX also target the youth market with orange-toned lip tints and high-saturation eyeshadows. Following its acquisition, 3CE has found it difficult to consistently win against the channels and budgets of these giants through brand positioning alone.
