In Vietnam’s hyper-competitive beauty market, brand visibility is a constant battle. For the established Korean cosmetics brand 3CE, the challenge was clear: how to cut through the noise on TikTok and convert brand awareness into tangible revenue. This TikTok Shop case study details how 3CE partnered with Ecomobi to execute a high-volume UGC strategy that became a powerful sales engine, culminating in a highly successful GMV campaign that generated 700M vndin just two months.
Campaign Snapshot: A High-Impact GMV Campaign
- Brand: 3CE (Cosmetics)
- Challenge: Overcome market saturation and drive measurable sales on TikTok Shop.
- Solution: A large-scale, performance-driven UGC Strategy delivered by Ecomobi.
- Platform: TikTok & TikTok Shop
Key Performance Metrics:
- 1,000 UGC videos produced in 60 days
- 700M VND TikTok GMV generated
- 35% conversion rate (vs. 15 – 25% industry average)
- 10M+ total views and 18% engagement rate.

The challenge: Driving Performance in a saturated market
3CE faced three core business obstacles that required more than a traditional marketing campaign to solve:
- Extreme market saturation: With countless new beauty brands and creators emerging daily on TikTok, gaining the attention of Gen Z consumers was increasingly difficult and expensive.
- The authenticity gap: Today’s beauty consumers don’t trust polished ads; they trust people. Gen Z and Millennial shoppers look to peer reviews, unboxing videos, and authentic testimonials to make purchase decisions. 3CE needed to bridge this gap with content that felt genuine, not staged.
- The need for measurable ROI: The campaign’s success could not be measured by views alone. The primary objective was to drive clear commercial value by boosting GMV on TikTok and achieving a high conversion rate.

The Solution: A performance-driven UGC strategy for Brands
To meet these challenges head-on, Ecomobi designed and executed a UGC-first strategy built on three core pillars: scale, authenticity, and performance. This wasn’t just about finding creators; it was about building a system to generate, optimize, and convert.
Strategic creator activation at scale
We activated a diverse mix of over 350 nano, micro, and mid-tier KOLs. This strategy ensured both relatable, high-trust content from smaller creators and amplified reach from larger influencers. Ecomobi’s platform managed the entire workflow for maximum efficiency.

Authentic content framework: “Everyday Beauty”
The campaign theme, “Everyday Beauty,” encouraged creators to integrate 3CE products into their real, daily makeup routines. This approach generated content that felt like a helpful tip from a friend, not a scripted ad.
- 1,000 UGC videos were produced in just two months, creating a constant stream of fresh, TikTok-native content.
- The videos leveraged trending sounds, filters, and formats, ensuring they blended seamlessly into the user’s “For You” page.
- Optimized hashtags like #makeup3cepartner and #depdachieu provided clear tracking while maintaining transparency with the audience.
Data-driven optimization and conversion
This campaign was engineered to drive GMV on TikTok Shop.
- Continuous monitoring: Ecomobi’s technology tracked the performance of every video in real time.
- Targeted amplification: Top-performing UGC content – videos with the highest engagement and purchase intent – was amplified with a targeted ad spend.
- Direct path to purchase: All efforts were geared towards directing engaged viewers to 3CE’s TikTok Shop, closing the loop between discovery and conversion.

“Success in social commerce isn’t about one viral video. It’s about building a sustainable system that turns authentic content into predictable sales. That’s the engine we built for 3CE.”
The Result
The data from this GMV campaign demonstrates the direct commercial power of a well-executed UGC strategy. The results exceeded all initial expectations and set a new standard for performance in the beauty category.
- 700M GMV generated: The campaign’s ultimate success was measured in sales, proving a direct and powerful ROI.
- 35% conversion rate: This exceptionally high rate proves that the creator-led content was highly effective at converting viewer interest into confirmed sales.
- 10 Million+ total views: The campaign achieved massive reach, successfully penetrating the target Gen Z audience and boosting brand awareness at scale.
- 18% average engagement rate: Far exceeding the typical 5% – 12% for the category, this metric confirmed that the content truly resonated with viewers, building a community, not just an audience.

Key Takeaway for Brands: This TikTok Shop case study provides a clear blueprint for success: a scaled, authentic UGC strategy is one of the most direct and effective ways to drive significant GMV on TikTok. By turning hundreds of authentic creator voices into a cohesive sales force, 3CE not only boosted its revenue but also solidified its position as a trusted, must-have brand for the next generation of consumer
