How TikTok Rewired Brand Loyalty

Lucas: If you’ve been watching the marketing landscape over the last six months, you’ve probably noticed something strange happening with brand loyalty. It’s not just that people are buying less, or even that they’re switching brands more often. It’s that the very concept of loyalty has shifted from a static identity to a dynamic participation model. Luna: Right, because for years we told brands to build a fortress around their identity, but now they have to build a playground where anyone can jump in. Lucas: Exactly. And the best example of this isn’t a legacy company like Coca-Cola trying to dance on TikTok. It’s Glossier. They didn’t just adapt to short-form video; they rewired their entire supply chain and customer service model to support it. Let’s look at how they did it, because it’s not about the videos themselves—it’s about what the videos enable. Luna: I remember when Glossier launched, it was all about that specific millennial aesthetic, but now it feels like every user is part of the product development team. Lucas: That’s the key word: participation. Traditional loyalty programs were transactional. You buy ten items, you get one free. That’s a math problem. Glossier built a social problem. They realized that on TikTok, a customer isn’t just a buyer; they’re a broadcaster. When a user posts a video about using a new shade of lipstick, they aren’t just sharing a review; they’re validating the brand’s existence in real-time. Luna: So the brand isn’t talking at them anymore; the brand is providing the tools for them to talk to each other. Lucas: Precisely. And here’s the concrete detail most marketers miss: Glossier changed their inventory system to accommodate viral spikes. If a specific shade goes viral on Tuesday, they need that shade in stock by Thursday. That’s not just marketing; that’s logistics. They aligned their backend operations with the speed of the platform. Most brands try to slow the platform down to fit their quarterly planning cycles. Glossier sped up to match the platform. Luna: But doesn’t that create a risk? If you’re reacting so fast to every trend, do you lose your core identity? Lucas: That’s the question every CMO is asking right now, especially as we head into the fourth quarter of 2026. The data shows that brands that try to maintain a rigid, static image see a twenty percent drop in engagement among Gen Z users. But brands that allow their identity to be fluid—letting users remix their products in videos—see a forty percent increase in repeat purchases. It’s counterintuitive, but it makes sense. People don’t trust perfection anymore; they trust iteration. Luna: It’s like the difference between a museum exhibit and a live concert. You want to be part of the energy, not just observe it. Lucas: That’s a great way to put it. And this brings us to the financial implication. For a long time, customer acquisition cost was the primary metric. But in this new model, retention cost is becoming just as important. Because if your customers are creating content for you, they are effectively doing your marketing for free. Glossier reports that nearly sixty percent of their top-performing content comes directly from user-generated sources, not their own creative team. Luna: So the ROI on those user-generated videos is essentially infinite compared to a paid ad spend? Lucas: In terms of reach, yes. But there’s a catch. The algorithm favors authenticity, not polish. So brands have to invest in communities, not just campaigns. They have to hire community managers who understand internet culture, not just traditional PR. This is a huge shift in hiring practices. We’re seeing more brands recruit former TikTokers into their leadership roles because they understand the nuance of what makes a video feel native versus forced. Luna: That’s interesting because I’ve noticed that some big beauty brands still struggle with this. They seem too afraid to let go of control. Lucas: Control is the enemy of virality. Think about the recent backlash against a major skincare line that tried to sanitize user comments. The moment they removed negative feedback from their TikTok page, engagement dropped by half. People could smell the artificiality. In contrast, Glossier leans into the messy parts. They feature videos where the makeup smudges or the lighting is bad. It signals that they value the human experience over the perfect shot. Luna: So vulnerability is actually a strength in this ecosystem? Lucas: It’s a currency. And the more you spend it, the more you earn in trust. Now, let’s talk about the mechanics of this participation. It’s not enough to just post a video and hope for the best. Brands need to create hooks that invite response. A hook might be a question, a challenge, or a template. For example, Glossier often asks users to show their skin texture before applying makeup. That’s a low-barrier entry point that encourages millions of people to participate without feeling like they need to be professional creators. Luna: It lowers the stakes. You don’t need to be an influencer to join in; you just need to be yourself. Lucas: Exactly. And that democratization is what scales the brand. When you lower the barrier to entry, you expand the total addressable market of your audience. Every single user becomes a potential micro-influencer. This changes how you measure success. You stop looking at views and start looking at participation rates. How many people used your hashtag? How many people duetted your video? How many people shared their own version of the product? Luna: It’s a completely different dashboard than what we’ve been using for decades. Lucas: It is. And it requires a different mindset from executives. Most boardrooms are still optimized for predictability. They want to know exactly what a campaign will deliver three months from now. But TikTok is inherently unpredictable. You have to be comfortable with chaos. Glossier’s leadership understands this. They allocate a significant portion of their budget to experimental content that might fail, knowing that the failures provide data and the successes provide scale. Luna: So they’re treating the platform like a laboratory rather than a billboard. Lucas: A laboratory is the perfect analogy. In a lab, you run experiments, you analyze results, and you pivot quickly. On TikTok, that cycle happens in hours, not quarters. If a video flops on Wednesday, you learn something on Thursday and adjust your strategy by Friday. This agility is what separates the winners from the losers in the current market environment. Luna: And it rewards those who listen closely to their community instead of just broadcasting at them. Lucas: Yes. And this leads to another critical point: the role of employee advocacy. Glossier encourages its own employees to create content. Not corporate-approved scripts, but genuine glimpses into their work life. This adds another layer of authenticity. When a customer sees a real person behind the brand, the connection deepens. It’s no longer a faceless corporation; it’s a group of humans solving problems together. Luna: That humanizes the brand in a way that polished ads never could. Lucas: Absolutely. And it creates a defensive moat. Competitors can copy your product, they can copy your price, but they cannot easily copy your community. Once a tribe forms around a brand, it becomes incredibly difficult to displace. That’s the ultimate goal of modern marketing: not just to sell a product, but to cultivate a belonging. Luna: So the product is almost secondary to the feeling of being part of something larger. Lucas: The product is the ticket to the club, but the community is the experience. And as we look ahead to the rest of 2026, brands that ignore this dynamic will find themselves increasingly irrelevant. The consumers are already moving toward participation. The question is whether brands are ready to follow. Luna: It’s a lot of pressure on the marketing teams to be agile and authentic at the same time. Lucas: It is. But the ones who figure it out will have a massive advantage. They’ll have a loyal base that defends them, promotes them, and evolves with them. That’s worth more than any amount of ad spend. Luna: So if these marketing conversations have sparked something you've actually used, or if you appreciate the ad-free nature of this show... Lucas: we deliberately don't run ads on these. If you want to support that choice, the link is buy me a coffee dot com slash fexingo — that's F. E. X. I. N. G. O. Luna: It really helps keep the lights on and the research deep, so thank you for considering it. Lucas: Now, back to the topic. One final thought on Glossier: they also use their community to test new ideas before launch. They ask users to vote on packaging colors or scent profiles. This not only ensures product-market fit but also makes the voters feel invested in the outcome. Luna: It’s pre-launch engagement that turns buyers into believers before they even spend a dollar. Lucas: Exactly. It’s a powerful tool for reducing risk and increasing excitement. And that’s the essence of loyalty in the TikTok era: it’s not given; it’s earned through continuous, visible participation. Luna: So the next time you post a video, think about how you can invite others into the conversation rather than just shouting into the void. Lucas: Right. Build the playground, and let them bring the toys. The rest will follow.
