China’s Ampoule Boom: How Concentrated Skincare Won Over Millennials

A Spanish skincare brand once sold 5 million ampoules in China during a single shopping festival. One unit every 2.49 seconds. That number is almost a decade old now, and it still gets quoted at every beauty conference I attend in Shanghai, because nothing since has made ampoules look like a passing fad.

The Chinese beauty market has gone through a lot since then: a pandemic, a domestic-brand boom, a domestic-brand correction, and now an AI search layer sitting on top of everything. Ampoules survived all of it. Concentrated, single-dose treatments are still one of the fastest-growing shelves in Chinese skincare, and the millennials who made them popular in 2017 are now buying them for their own kids’ skincare drawers.

I run GMA from Shanghai, where we’ve spent over a decade helping foreign beauty brands, Martiderm among them, build a presence in this market. This article explains why ampoules caught on, what changed in the market since the original Martiderm case, and what a smaller brand needs to do differently in 2026 to get the same kind of traction.

Chinese skincare buyers keep getting more literate. Their expectations move faster than most brands can track, and a new ingredient or format can go from unknown to mainstream in a matter of months in a market this connected.

Ampoules, small glass or plastic vials holding a concentrated dose of active ingredients, have been part of that story since around 2016. What’s changed is the size of the audience paying attention to them.

On Xiaohongshu, posts tagged with ampoule-related keywords now number in the hundreds of thousands. Users compare formulas, cite percentages, and argue about which brand’s version irritates sensitive skin. That habit, dissecting a product down to its ingredient list before buying it, has only gotten stronger since the format first took off.

What is an ampoule, exactly?

Think of it as a serum with the concentration turned up. Ampoules carry a higher dose of active ingredients than a standard serum or cream, built to address one specific concern: dark spots, dehydration, loss of firmness. The single-use, airtight vial format exists for a reason. It stops a buyer from over-applying a strong formula, and it keeps the product stable until the moment it’s opened, which matters more with unstable actives like vitamin C.

They’re also just easy to travel with, which never hurts in a market where skincare gets carried to the office, to the gym bag, to a weekend trip.

How Martiderm built its China business

Martiderm is a Spanish derma-cosmetics brand that entered China in 2016 through Tmall Global. In its first five months, it passed 20 million CNY in sales. By the end of 2017, that number had grown tenfold to around 200 million CNY.

Then came Singles’ Day: over 5 million ampoules sold in one festival, one every 2.49 seconds. The brand’s traction pulled a wave of attention toward the whole category, and Spanish beauty in general picked up an outsized share of ampoule sales on Tmall Global relative to other countries.

Why ampoules keep winning under 2026 rules

The Chinese beauty market has cooled overall. During the May to June 2026 shopping window, beauty and personal care sales across platforms came in at roughly 42.5 billion CNY, down about 1.6% year on year, and several long-time domestic leaders lost ground to international names in the rankings. That correction is real. But it isn’t hitting every segment the same way.

Functional, efficacy-driven skincare, the category ampoules sit inside, has kept growing through the slowdown. According to industry research firm 智研咨询 (Zhiyan Consulting), China’s functional skincare market grew from about 7.4 billion CNY in 2016 to roughly 48 billion CNY by 2024, making it the fastest-growing segment in the entire beauty and personal care industry. Exports of Chinese-made functional skincare products crossed 5 billion USD for the first time in 2025, with medical-grade repair products accounting for over a third of that figure.

The first half of 2026 pushed the trend further. Moisturizers claiming two or more specific efficacy benefits now make up 72% of all moisturizer sales in China, and medical-grade creams grew 137% year on year over the same period. A single-benefit, vaguely-worded “hydrating cream” doesn’t sell the way it used to. Buyers want the product to name its job and prove it can do it, which is exactly the pitch an ampoule has always made.

Efficacy claims, not broad positioning, are what moves skincare product in China right now.

Ampoule buyers are young, and they’re not getting easier to impress

On Tmall, women aged 25 to 30 remain the core ampoule demographic. The belief that skin aging starts at 25 is widespread enough in China that it has its own term, kang chu lao (抗初老), roughly “fighting the first signs of aging.” Women in their early twenties build a full anti-aging routine around that belief, years earlier than most Western consumers would.

A Kantar China report found that post-90s and post-80s consumers spend close to 100 CNY more per capita on skincare than consumers born before 1960. That generation is also far more willing to try an unfamiliar brand than their parents were, which is the opening a foreign challenger brand needs.

…and they read the ingredient list before they read the review

Between October 2018 and January 2019, Baidu searches for skincare ingredient terms rose 331%, according to a Gartner L2 report on WWD. That was the early signal. Mintel’s 2026 China consumer research now describes a market where “ingredient stacking” as a marketing tactic has stopped working on its own, and brands are being pushed toward long-term, proof-based value competition instead of chasing the next trendy compound name.

A blogger used to need a before-and-after photo and a good caption. Now they need to explain the mechanism. Ann, a millennial skincare KOL with over a million followers across platforms, started documenting her ampoule routine in 2017 to treat acne-prone skin. Her stated rule for judging a product hasn’t changed since: check the ingredient list and the clinical claim before anything else.

Male beauty blogger Fang Junping built one of the most-watched ampoule videos on Bilibili by reviewing four products at different price points and explaining, plainly, when to introduce an ampoule into a routine and what sensitive-skin users should watch for. On Zhihu, a blogger going by San Mushu, a self-described chemistry researcher, questioned whether Lancôme’s single-dose capsule packaging actually preserved ingredient activity, and warned first-time users about the sensitivity risk that comes with a concentrated formula. Both posts still get cited in ampoule discussions today.

The 2026 playbook: where the sales conversation actually happens now

Three things have changed since Martiderm’s first campaign, and a brand entering the category today needs an answer for all three.

Xiaohongshu has become a search engine, not just a feed. Chinese users increasingly open the app already knowing what problem they want solved: which ampoule works for post-acne marks, which one is safe during pregnancy. Ranking inside that search behavior means writing content around the question, not the brand name. A search-first content strategy on Xiaohongshu looks closer to an FAQ than a lifestyle post.

AI search has entered the funnel. DeepSeek and Doubao now answer product questions directly, and they don’t pull from one source. They pull from encyclopedia-style entries, e-commerce Q&A sections, Zhihu answers, and ingredient databases, then blend them into one answer. A brand that only has a nice product page and no presence in those secondary formats is invisible to that layer entirely. We’ve written more on how WeChat’s DeepSeek integration changes brand discovery, and the same logic applies to a skincare ampoule as it does to any other product category.

KOC content converts better than KOL reach. A single mega-influencer post gets views. A cluster of ten to twenty mid-tier creators, each doing an honest ingredient comparison, builds the kind of repeated, cross-referenced content that both Xiaohongshu’s algorithm and AI search engines treat as trustworthy. It’s slower to set up than one celebrity endorsement, and it performs better over a full quarter.

How the Martiderm campaign was built

Martiderm’s founder, Jose Marti Tor, opened a pharmacy in 1952 making custom antioxidant skincare for clients. In 1989, that formula work turned into a high-concentration vitamin C and protein-polysaccharide ampoule. The brand name Marti Derm followed in 1997, once the product was ready for a wider market, developed with input from dermatologists and pharmacists.

When Martiderm brought that formula to China, our work with the brand focused on three things: KOL marketing built around real ingredient explanations, social commerce integration so a viewed post could turn into a purchase without friction, and consistent branding across every touchpoint. The result was over 20 top-tier KOL reviews, a body of content strong enough to keep generating organic reach long after the campaign budget stopped, and a positive return on the marketing spend.

A smaller brand, the same playbook: Miro’s ampoule launch

Miro runs a small skincare line out of Slovakia, built around a mineral-rich thermal spring water his family has bottled for three generations. In 2025 he tried to bring a concentrated ampoule version of the product to China through a standard Tmall Global storefront, translated product copy, a modest paid traffic budget, no local content plan. Three months in, he’d sold 340 units.

The problem wasn’t the product. It was that nothing in the listing answered the question a Chinese buyer actually asks: what does this ingredient do, specifically, and where’s the proof? A translated European ad speaks to a European buyer’s assumptions, not a Chinese one.

We rebuilt the approach around the mineral profile itself. Content shifted to Xiaohongshu first, framed as ingredient breakdowns rather than lifestyle shots, comparing the thermal spring mineral complex to more familiar Chinese and Korean actives. Ten mid-tier KOCs, each with followings between 10,000 and 60,000, produced side-by-side comparison videos and posted their own skin tests over several weeks. We opened a Xiaohongshu shop alongside the Tmall listing so a reader could buy at the exact moment the ingredient story landed, instead of clicking away and never coming back.

It worked because it matched how the category already behaves in China: buyers verify before they buy, and they trust a cluster of ordinary-looking accounts over one polished ad. Over the following quarter, Miro’s ampoule line sold around 3,400 units combined across Xiaohongshu shop and Tmall, at an average order value of 312 CNY. That’s not a Martiderm-scale outcome, and it wasn’t meant to be. It got the SKU to profitability in China for the first time, and gave Miro a content library he could keep using in the next campaign.

FAQ

Do we need celebrity-level KOLs to launch an ampoule line in China?

No. A cluster of mid-tier KOCs doing honest ingredient comparisons usually outperforms one high-cost celebrity post, especially for a first launch. Save the bigger names for once the ingredient story already has proof behind it in the form of real user content.

Can we sell a concentrated skincare product in China without a local entity?

Yes, through cross-border e-commerce channels like Tmall Global, which don’t require a Chinese business license or local manufacturing. You still need to register the product correctly for cross-border sale and make sure your ingredient claims match what’s permitted under Chinese cosmetics regulation.

How long before an ampoule launch shows real traction?

Plan for a full quarter before judging results. The first few weeks build the content library and the KOC relationships; the sales usually follow once that content starts getting cross-referenced by other users and picked up in search.

Is Xiaohongshu enough, or do we still need Tmall or Douyin?

Xiaohongshu is where the research happens, but it’s not always where the purchase closes. Most ampoule brands still need a transaction channel, whether that’s a Xiaohongshu shop, a Tmall Global storefront, or a Douyin store, sitting right behind the content.

Does AI search (DeepSeek, Doubao) actually matter yet for a niche skincare brand?

It’s becoming part of how buyers pre-screen products before they even open Xiaohongshu. You don’t need a dedicated AI search budget on day one, but your ingredient claims should exist consistently across your product page, e-commerce Q&A, and any PR or Zhihu presence, since that’s what these tools pull from.

GMA has run China market entry campaigns for foreign skincare and derma-cosmetics brands since 2012, from Martiderm’s original Tmall Global launch to smaller ampoule and serum lines still finding their footing. We build the ingredient-first content, the KOC network, and the shop setup together, rather than treating them as separate projects.
