TikTok’s comment sections have become the primary driver of first-time beauty purchases, fundamentally reshaping how consumers discover and buy products on social platforms.

The shift represents a move from traditional top-down marketing to peer validation. After viewing affiliate content on TikTok, 77% of users search for the same product to read comments and see how brands position their offerings, according to Donte Murry, North America director of TikTok’s beauty vertical.

“What was true when I started at TikTok — that users are coming to the platform to discover new products — is still true, but I think this behavior is evolving,” Murry told Glossy. “Brands should think about what you want to reverse engineer in the comments. What kind of conversation do you want to start that can help influence that first purchase?”

TikTok Shop has capitalized on this behavior shift to become the fourth largest health and beauty e-commerce retailer in the United States. The platform generated $4.4 billion in lifetime health and beauty sales, with 79.3% of all TikTok Shop purchases falling into this category.

The numbers show explosive growth. Health and beauty sales jumped 84% year over year, while overall US sales grew 407% in 2024 and another 108% this year, reaching $15.82 billion. Americans now spend an estimated $32 million per day shopping on TikTok.

The comment-driven purchase behavior differs from repeat buying patterns. While comments drive first purchases, second purchases from the same brand typically stem from educational content like tutorials explaining product science and ingredients.

“This growth represents a real shift in how shoppers discover, engage with and ultimately purchase their beauty and wellness products,” said Anna Mayo, VP of beauty and personal care thought leadership at Nielsen IQ. “What’s showing up in our feeds is becoming just as important as what sits on the store shelves.”

The platform has compressed the traditional marketing funnel. Discovery, validation, entertainment, and checkout now happen within the same scroll, eliminating the typical journey from awareness to consideration to purchase.

Science-backed content performs particularly well. Murry noted that some top-performing videos feature creators explaining ingredients in front of whiteboards or breaking down why products work.

The average TikTok Shop health and beauty consumer spends around $118 annually, with one in four users purchasing something after seeing beauty content. Live shopping sessions focused on beauty grew 90% in 2025 as brands used real-time interaction to influence purchase decisions.
