JennyBrown's R&D Transparency Builds Skincare Trust

In the high-end skincare industry, how brands build product competitiveness starting with their raw materials has become a key focus. Swiss brand JennyBrown recently showcased its entire R&D system—from natural ingredient sourcing to final formulation—through its skin research center in Switzerland. This system is not merely a marketing tool; it directly addresses current consumer demands for transparency, efficacy, and traceable safety in skincare ingredients.

JennyBrown’s Global Vice President Marie Keller said in an interview that the brand has observed a profound trust reconstruction in the skincare market over the past few years. “Consumers are no longer satisfied with brand stories. They want to know exactly what’s in each bottle, where those ingredients come from, why they work, and whether they’re safe,” she noted. This trend is especially pronounced among Millennials and Gen Z, who tend to favor brands that provide complete ingredient information backed by third-party certifications.

JennyBrown’s response has been to build a traceable supply chain starting at the raw material level. The brand currently sources ingredients from more than ten countries, encompassing approximately 328 raw materials from 93 plant species. Over 98% of these are green ingredients, and 96% come from traceable certified formulas. For the White Truffle Collection, the core ingredient—Italian white truffle—must be hand-harvested by trained collectors during a specific season, then extracted at low temperatures to preserve its active compounds. Product Director Nadine Bronx explained that white truffle contains more than 50 physiologically active ingredients that promote collagen and elastin synthesis, forming the basis for the collection’s brightening and repairing effects.

But precious ingredients are only the first step. The real technical challenge is ensuring these active compounds are actually absorbed by the skin and continue to work over time. JennyBrown’s R&D team has spent more than a decade at the Swiss skin research center refining two core technologies: Nano-Scale Molecular Delivery Technology and Smart Controlled-Release Microsphere Technology. The former breaks active ingredients into nano-sized particles, increasing absorption by a factor of 20 compared to conventional products. The latter uses encapsulation to release active substances continuously over 15 hours, extending the product’s repair cycle. Bronx revealed that these technologies are not one-time achievements but are continually optimized with each product iteration. “We only have 16 SKUs, but every single one has gone through multiple upgrades because we have a very strict definition of what ‘effective’ means,” he said.

On safety, JennyBrown maintains a restricted ingredient list it calls the “blacklist.” The brand has studied virtually every skincare ingredient globally, combined with clinical research from multiple institutions, to identify over 120 banned substances. Every product undergoes more than 1,000 allergy tests and over 60 skin tests before launch. Additionally, the brand holds ECOCERT Natural Cosmetics certification and NATRUE Organic Cosmetics certification, which are uncommon among high-end skincare brands. Keller believes that certifications are not just about meeting standards but about providing verifiable trust to consumers. “We voluntarily invite third-party organizations to audit our formulas and production processes. That’s more convincing than any advertisement,” she said.

Notably, JennyBrown has chosen not to expand its product line aggressively. The brand currently covers only facial skincare, with six collections—White Truffle, Caviar, Phalaenopsis, Matsutake, Dragon’s Blood, and Edelweiss—totaling 16 SKUs. This restraint stems from the brand’s commitment to depth. Bronx noted that adding a new collection requires years of R&D and extensive ingredient testing, and the brand prefers to concentrate resources on a few products to ensure each meets a “precision efficacy” standard. “We won’t launch filler products just to satisfy channel demands. That would only dilute our core value,” he said.

In consumer communication, JennyBrown uses the same transparent approach as its product development. Every product comes with an authenticity card, and users can verify product authenticity, details, and after-sales service through a unique code. The brand’s official website and official online store also publish the full ingredient list for each product, including the INCI name, purpose, and processing details for every ingredient. For example, the JennyBrown White Truffle Essence lists its core active ingredients—white truffle extract, alpine edelweiss extract, sea fennel callus culture filtrate, and centella asiatica extract—along with base humectants like butylene glycol and 1,2-hexanediol, and notes the source and processing method for each, such as “naturally fermented from sugarcane” or “Swiss Alpine edelweiss, low-temperature ultrasonic extraction.” This transparency reflects the brand’s confidence in its R&D capabilities and is a proactive choice to address market information asymmetry.

From an industry perspective, the biggest challenge facing high-end skincare brands in recent years has not been competitors but a trust crisis among consumers regarding “luxury products.” In the past, high prices were often tied to lavish packaging, celebrity endorsements, and exclusivity. But with the rise of social media and ingredient-conscious consumers, more people are questioning whether expensive products truly deliver value. JennyBrown’s logic is to replace stories with facts. Keller emphasized that the brand does not deliberately highlight labels like “royal use” or “exclusive clientele,” even though such users exist. “Our celebrity users—like French diamond jeweler Valérie Messika and designer Sabine Marcelis—became loyal customers because they saw changes in their skin after trying the products, not because of marketing,” she said.

In product testing, JennyBrown also takes a pragmatic approach. Instead of mass-distributing free samples like some emerging brands, it collects feedback through targeted small-scale trials. Bronx explained that before launching the White Truffle Luxury Cream, the brand invited 50 women of different skin types and ages to use it continuously for four weeks, recording daily experiences and skin changes. The results showed that over 90% of participants felt improved skin firmness and noticeable brightening after two weeks. These data were later used to refine the formula and serve as internal references after launch. Although the brand does not publicly disclose the exact numbers, this process has become a standard part of JennyBrown’s product development.

In its channel strategy, JennyBrown also maintains restraint. The brand operates only eight physical stores worldwide: in Geneva and Zurich (Switzerland), Munich and Düsseldorf (Germany), Paris (France), Milan (Italy), and Beijing and Shanghai (China). The two stores in mainland China are located at Beijing SKP and Shanghai Plaza 66, both top-tier luxury shopping destinations. This layout is not about quantity but about establishing flagship brand experience in key markets. For most consumers, the brand reaches them through online channels, including its China website, JD.com flagship store, Tmall flagship store, Douyin flagship store, and WeChat official store. Keller noted that the WeChat official store typically offers the best discounts, an adjustment to suit Chinese consumer shopping habits, but the discount depth is always controlled to avoid damaging the brand’s premium positioning.

From R&D to production, from raw materials to formulas, from testing to sales, JennyBrown’s entire chain revolves around a single goal: making every product stand up to scrutiny. This pragmatic approach stands out in today’s often flashy beauty industry. Bronx summarized the brand’s vision: not to become the largest skincare brand by market share, but to be the one consumers trust most. “We believe that when consumers truly understand the science and sincerity behind our products, they will make rational choices,” he said.

Looking at industry trends, JennyBrown’s case also suggests a possible direction for high-end skincare brands. On one hand, the integration of biotechnology and natural ingredients is accelerating, requiring brands to have both deep R&D capabilities and supply chain control. On the other hand, transparency and verifiability will become the foundation of brand trust, not an add-on. Brands that can present complete information about ingredients, efficacy, safety, and certifications will find it easier to hold their ground in a fiercely competitive market. Keller said JennyBrown will continue to invest resources in the Swiss skin research center, exploring more extraction technologies for natural active ingredients, while also strengthening commitments to environmental sustainability, including reducing carbon emissions, adopting green packaging, and rejecting animal testing.

“We’re not running a marketing experiment,” Keller said. “We’re just doing what we believe is right: using the best raw materials and the most rigorous technology to bring consumers truly effective facial care products.”
