Perfect Diary went from $16B to $378M — the D2C bubble that burst

Perfect Diary, China's most celebrated D2C beauty brand, listed on the NYSE in November 2020 at a peak valuation of over $16 billion. Its rise was built on a relentless marketing machine: a pyramid of celebrity endorsements, KOL seeding and grassroots reviews that pushed marketing spending from ¥309 million in 2018 to ¥3.4 billion in 2020 — a tenfold increase in two years. By 2021, marketing consumed 68.6% of revenue, while R&D never exceeded 3%.

The model worked until it didn't. When traffic costs rose and investor patience ran out, the underlying weakness was exposed: Perfect Diary had built a brand on awareness, not loyalty. Customers had no reason to stay. Cumulative losses from 2020 to 2024 reached ¥6.5 billion. By early 2026 the stock was at $4.11, down from $25.47, and the company's market cap had fallen to $378 million — a 97% collapse.

Spent 68% of revenue on marketing and under 3% on R&D, so when traffic costs rose, customers had no reason to stay and 97% of the $16B market cap evaporated.

The company spent 68% of revenue on marketing and less than 3% on R&D — a brand built on awareness without product depth has no moat when traffic gets expensive

The D2C model worked during the venture-capital boom but had no path to profitability once the funding environment tightened

A brand built on marketing spend is a campaign, not a company — when the spending stops, the customer leaves
