Not all influencer events are created equal. Some make headlines but quickly disappear after the press release. Others quietly outperform expectations, driving product demand, capturing global attention and sparking long-term brand equity. But what separates the two?
In the beauty industry, influencers have the power to make or break product launches and campaigns. Whether they’re testing new makeup, showcasing skincare routines or reviewing the latest viral beauty products on TikTok , influencers connect brands with consumers in a way that feels genuine and relatable. But hosting a beauty event that successfully leverages influencers isn’t as simple as sending out invites. The success of these events lies in activating the right Voices: Celebrities, Influencers, Media, Owned Media and Partners, to fuel awareness and conversion.
Most importantly, after the event is over, it’s critical to measure what actually moved the needle. Was it a specific platform? A media placement? A regional voice? That’s where metrics like Media Impact Value® (MIV®) come in. MIV is Launchmetrics’ proprietary algorithm that assigns a dollar amount to brand exposure across print, online and social.
But to fully understand how influence spreads, we go one step further. Our Voice Echo framework captures both the direct impact of an ambassador and the ripple effect their presence creates through third-party coverage, media amplification and community-led conversations.
In this blog, we break down five recent beauty events and explore how each brand nailed their Voice strategy to deliver measurable impact.

Curated for Fashion, Lifestyle & Beauty brands, the checklist provides brands a smarter way to plan, execute and measure events.
1. Rihanna’s “Fenty Hair” Launch
When Fenty launched its much-anticipated haircare line in 2024, the brand orchestrated a holistic strategy that went beyond simply relying on Rihanna’s reach, employing other Voices to amplify and maximize their product launch campaign efforts to drive awareness. The team staged a fully immersive in-person event in Los Angeles that doubled as a product showcase and a small brand world. “Mane Street”, the activation space at Nya Studios, was designed as a town square where creators, press and celebrities could explore the new line through hands-on installations, live demos and themed spaces like the “Hair Heaven” salon.
In the first 48 hours, the campaign generated $9M in MIV. Influencers were responsible for 60% of that total ($5.37M). Yet the single highest-value placement came from Rihanna herself: one Instagram post generated $427K in MIV. Naturally, the U.S. led with $4.67M in total MIV. However, UK-based media brought in $133K, driven in part by Glamour UK’s coverage of Rihanna’s hairstyle—proof that even localized activations can drive global impact when picked up by the right outlet. While the Media Voice only accounted for 17% of the total MIV, its placements were high-value, with coverage like Cosmopolitan’s personal product review bringing in $25K. This suggests that while creators were the volume drivers, trusted editorial content added weight to the story as well.
An unexpected high-performing Partner placement came from Indian designer brand Sabyasachi Mukherjee. Rihanna wore one of their necklaces to the launch and one Instagram post alone generated $175K, pointing to a potential new market focus for Fenty.
Fenty structured the event to deliver influence at every layer: celebrity to spark conversations, creators to spread the message, media to legitimize and global partners to extend reach beyond the room. It’s a blueprint for how events move from moment to movement, by tapping into the right Voices.
2. KIKO Milano and Emma Roberts
In June 2024, KIKO Milano hosted “Beauty & the Book”, a brand event centered around their new global ambassador, Emma Roberts. The event was held at The Bowery Hotel in New York and aligned the launch of new lip shades with Robert’s book club, Belletrist. The guest list blended beauty creators and BookTok influencers, tapping into both product and cultural conversation.
Within 48 hours, the campaign generated $2M in MIV. Roberts herself contributed $244K via a single Instagram post, about 12% of the total MIV for the campaign. But the more interesting insight lies in the after-effect. 64.7% of the total MIV came from Indirect Echo, that is, content from creators, partners and media who weren’t directly part of the core campaign but still referenced or amplified it through posting about it and generating conversations.
This reflects what we found in our Brand Ambassador Marketing Report, which shows that 77% of ambassador-led impact typically comes from Indirect Echo. Emma’s presence created a strong narrative center, but it was the global network of Voices, from Smoda in Spain to Elle Italy, that carried the story across markets. In fact, Italy, KIKO’s home market, outperformed the U.S. in MIV ($519K vs $404K), despite the event being held in New York. That’s why brands activating on a global level need precision, from local PR to international media planning. (See our full KIKO Milano case study for how they scale across 60+ markets.)
Owned Media was another strong contributor. KIKO’s global channels drove $462K, 23% of the total, showing that the brand maximized the event across its own platforms and didn’t just rely on external coverage. Instead of just activating an ambassador, they built a narrative vehicle that others could pick up and carry. By grounding the event in a real cultural overlap (literature, lifestyle and beauty) the brand created an entry point for a range of Voices to engage authentically.
3. e.l.f. Cosmetics: Run Club in London
To launch its new Power Grip Dewy Setting Spray in 2024, e.l.f. Cosmetics did something different. The brand leaned into fitness culture, hosting its first-ever e.l.f. Run Club during London Marathon week. The event brought together a group of creators for a 5K jog in Battersea Park, led by fitness influencer Misha Grimes and running coach Anya Culling. The goal was to test the setting spray in the real-world and of course, document every step.
The campaign prioritized performance and authenticity from the start. Attendees posted real-time reviews, selfies after the run and behind-the-scenes stories that made the product feel tested, trusted and community-approved. But the impact of the campaign stretched far beyond the run itself. Within 48 hours, the event generated $1.78M in MIV with Influencers such as Lucy Reeves and Melissa Cowell driving 76% of the total ($1.34M). By tapping into the intersection of beauty and wellness, an increasingly relevant topic for creators focused on routines, performance and self-care, e.l.f positioned its setting spray as a lifestyle product. This allowed fitness and beauty influencers to turn the event into an opportunity to extend the product story across their content calendars.
e.l.f. also strategically invested in content across its Owned Media, accounting for 10% of the total MIV ($145K). The brand developed platform-native assets designed to reinforce the product’s wearability: on Instagram, a branded Instagram reel generated $69K, while a TikTok captured during the run pulled in $51K. These assets demonstrated how the brand effectively supported creator content with its own native storytelling.
Interestingly, while the event was hosted in London, a big part of the overall impact came from across the U.S. That boost came from creators who continued the product story in creative ways. For example, influencer Chloe Roberts filmed herself “testing” the spray’s hold during hair salon appointment.. Another creator, @katie.org, made a viral TikTok seeing whether the product could even help perfume last longer, a post that alone brought in $72K in MIV.
The real genius of the event was in how it sparked a wave of user-generated content. Runners, creators and everyday consumers of the brand posted their own “durability tests,” building proof points that felt organic, personal and perfectly aligned with e.l.f’s accessible, performance-first positioning.
4. YSL Beauty: Loveshine Factory
When YSL Beauty introduced Dua Lipa as its Global Makeup Ambassador in March 2024, the brand activated a two-day, dual-format experience in Paris: a VIP influencer event at Silencio nightclub, followed by a public-facing “Loveshine Factory” pop-up. While Dua was clearly the face of the activation, she wasn’t the only Voice in play. The event also featured other brand ambassadors such as Sho Hirano and K-pop group NewJeans, both of whom played a significant role in shaping the campaign’s regional and platform-level performance, especially across APAC.
In just 48 hours, the activation generated $9.96M in MIV. Of that total, Influencers accounted for $4.44M, Celebrities $2.81M and Media $2.29M. Dua Lipa herself brought in $761K from three posts. Sho Hirano and NewJeans contributed an additional $1.25M combined, proving that while Dua was central to the global campaign, the impact was deeply localized and ambassador-led. Of the total MIV, a striking 89.5% came from Indirect Impact, meaning the majority of value was created by the ripple effect rather than direct posts. That includes fan content, creator buzz, and global press referencing the event, especially in APAC. In Japan, Sho Hirano alone generated $1.41M, while in Indonesia, Harper’s Bazaar Instagram post brought in $215K. This was reinforced when looking at the platform breakdown: Instagram drove 57% of total MIV, TikTok 14%, but regionally, the top-performing platforms were mostly APAC-based or heavily used by APAC creators such as Weibo and WeChat.
The role of influencers, particularly those outside the U.S., was also telling. Turkish beauty creator Duygu Özaslan Mutaf generated $44.3K from a single Instagram post at the event. But even more interestingly, her TikTok before the event, showing her getting ready, brought in $32K on its own. That moment highlighted that event ROI doesn’t just happen at the event; it happens in the buildup, anticipation and the way creators treat the experience as something worth talking about before and after the actual moment. By spotlighting brand ambassadors and aligning them with the right platforms and local media, YSL built a campaign that scaled globally while remaining relevant in key markets.
5. Kosas: Cabo Creator Trip and Product Launch
Kosas, a clean beauty brand known for its skincare-first formulas and minimal aesthetic, entered the influencer trip space for the first time in March 2024 with a multi-day retreat in Cabo. The trip strategically coincided with the launch of DreamBeam Sunlit, a new tinted version of the brand’s best-selling mineral sunscreen. In just 48 hours, the campaign generated $8.73M in MIV.
92% of the total MIV came from Influencers. Mikayla Nogueira, known for her fast-paced reviews and loyal following, contributed $2.07M across 12 posts. Mid-tier creators like @maybeboth and Glamzilla brought in $660K and $399K. What stood out was the content mix: rather than focusing only on the product, creators leaned into lifestyle-driven narratives, from travel diaries and packing routines to off-guard hotel tours, extending the relevance of the campaign across TikTok, Instagram and YouTube.
This range created a sense of authenticity while still anchoring the launch. The brand didn’t over-script the experience but ensured the product appeared naturally throughout the content. That balance was essential in building sustained visibility.
The U.S. led with 71% of the total MIV. However, Canada emerged as a secondary market with $544K in value, thanks in part to Glamzilla’s viral TikTok ($75.7K). One Byrdie article announcing the product during the trip generated $47.3K in MIV, while Kosas’ own TikTok post, uploaded mid-retreat, drove another $45.2K. Together, these placements showed that rather than leading the narrative, Kosas stepped in at the right moment supporting the creator-led buzz without disrupting its flow.
The real success of the trip was in how Kosas integrated the product into a broader content ecosystem. Rather than centering every post on the sunscreen itself, the brand built a moment that creators could naturally embed into their routines giving the launch relevance across formats, regions and platforms without ever needing to over-direct the narrative.
The key to these winning influencer event strategies
The success of these events went deeper than the guest list or Influencer reach, it was about strategic execution. Each brand activated the right mix of Voices, timed their content across platforms and built moments that extended far beyond the physical space. The common thread between all of them? Thoughtful planning backed by data.
