Emily Weiss started Into The Gloss in 2010 while working in fashion at Vogue, interviewing women about their actual beauty routines instead of running polished editorial spreads. The blog's signature feature, Top Shelf, showed real bathroom shelves and asked real questions about what people used and why. Over four years it built a large, loyal readership, people who kept coming back because the content read like it came from a friend, not a brand.
Weiss treated that readership as an ongoing source of research. Comments, questions, and complaints from Into The Gloss readers shaped what would become Glossier: which products people actually wanted, what annoyed them about existing beauty brands, where the real gaps were. By the time she was ready to build a product line, she already had a good idea of what her first customers needed, because they had been telling her for years, in public, in the comments.
Glossier launched in October 2014 with four products: Perfecting Skin Tint, Priming Moisturizer, Balm Dotcom, and Soothing Face Mist. Weiss announced it the same way she had built the audience: a long, personal letter published on Into The Gloss itself, addressed directly to her readers. "Glossier.com launches today, right now, and is the beginning, I hope, of a new way of looking at beauty, that of course began with ITG," she wrote. There was no separate marketing campaign to build. The blog's own comment section and social following were the day one distribution.
The same loop kept running after launch. When Glossier later developed the Milky Jelly Cleanser, the team asked readers what their ideal cleanser would do, then dug through 381 responses before formulating the product. The habit stayed constant from day one: don't guess what the customer wants, ask the community that already trusts you, then build exactly that.
- Ran Into The Gloss for four years before launching a product, turning it into both audience and research.
- Used reader comments and direct questions to identify real gaps in the beauty market before building anything.
- Announced the Glossier launch as a personal letter on the same blog, not a separate ad campaign.
- Kept the reader feedback loop running after launch, sourcing hundreds of responses before formulating new products.
