Beauty & Cosmetics Influencer Marketing Agency

Several forces are reshaping beauty influence and redefining how campaigns must be built.

Skincare, long confined to the face, is now spreading across body, hair, lips and scalp. Consumers expect active claims, identified ingredients and an argumentation close to that of dermo-cosmetics, even on entry-level products. For brands, this translates into more educational, precise and science-led influence content.

Dermatologists, pharmacists, nurses and cosmetologists have become major voices of authority. Their presence in an influencer campaign is no longer optional: it is a prerequisite for credibility, especially on active skincare, sun care, anti-ageing and post-procedure products.

Routines, before-and-afters, duets and unfiltered reviews now set the tempo. A beauty brand unable to test native TikTok formats quickly risks missing a significant share of demand, particularly among Gen Z and younger millennials.

The era of simple product placement is over. Marketing teams now demand qualified KPIs, post-campaign conversion measurement and transparency on audience composition. We share that requirement: our approach is natively anti-fake, properly equipped, and data-led.

For NIVEA, we act as influence partner at both international and French level. Internationally: strategic counsel, influence toolkits for every launch, deployed consistently across markets, and international events gathering key creators around the brand's highlights. In France: day-to-day campaign management, with the right creators and formats. The international launch of Luminous 630 illustrates this dual role: 45 creators activated across markets, with a 5.67% engagement rate.

For Eucerin, a dermocosmetic reference, the challenge since 2021 has been to articulate the laboratory's scientific credibility with modern, desirable influence communication. Our set-ups pair expert voices, able to carry the active promise of the formulations, with skincare creators recognised for the quality of their educational content.

A brand such as Nivea does not have the same expectations as a dermo-cosmetic laboratory like Eucerin. Yet a single group can run both strategies. Our method allows us to adapt tone, formats and talent profiles to each positioning while maintaining overall coherence.

We systematically work with our beauty clients on a shared KPI framework aligned with their objectives: qualified reach, effective views, meaningful engagement, expert audience adherence, sentiment, and incremental sales when data allows. Measurement is designed at the brief stage, not after the campaign ends.

We have formalised a proprietary five-step method that we apply to every beauty campaign.

We start from weak signals, emerging queries, active communities and the creators who truly perform with the target audience. Analysis precedes ideation.

The creative concept is never bolted on. It extends the codes, ambassadors and existing promises of the brand to strengthen equity rather than dilute it.

We select complementary profiles, mixing dermatology experts, skincare creators, lifestyle voices and beauty ambassadors, with systematic authenticity checks.

The best-performing content is reused through paid social, clipping and, where relevant, press relays. Every deliverable lives several lives.

We deliver clear readings, with actionable recommendations for the next campaign cycle.

We have supported Neutrogena since 2017, at French and international level. At the EADV congress, the major scientific event of European dermatology, we orchestrated for Kenvue the European launch of Neutrogena Collagen Bank: asserting the brand's dermatological credibility with health professionals while making the innovation accessible and engaging for the general public — the Collagen Bank pop-up generated more than 20 million impressions.

For Le Petit Marseillais, the emblematic brand of accessible, natural care, we have been designing influence programmes since 2021 that champion products rooted in daily life, with creators who share the brand's generous, warm DNA — and strong demands on audience authenticity.

These four cases reflect our daily work as a beauty and cosmetics influencer agency: adapting the method to the positioning, selecting the right voices, proving the impact. For premium houses and the codes of high-end beauty, discover our approach to luxury influence.

A specialised influencer marketing agency knows the beauty creator landscape, their real specialties (skincare, haircare, makeup, sun care, dermo) and the actual performance of their audiences. It can assess the credibility of an expert profile. At Matriochka, this beauty expertise sits alongside multi-sector teams, letting us cross-pollinate learnings with demanding sectors like health and tech.

We define the indicators with the client upfront, depending on the objective: awareness, consideration, conversion or image. We track qualified reach (watch time, completion rate), useful engagement, brand sentiment shifts, incremental search and, when the data is available, contribution to sales.

Formats that combine usage demonstration, ingredient education and a personal register: authentic routines, short multi-episode series, collaborations between experts and lifestyle creators, and long-form YouTube for technical products.

Yes. Derma-influence has become a standard in beauty: dermatologists, pharmacists and cosmetologists are essential authority voices on active, sun, anti-ageing and post-procedure skincare. We build mixed ecosystems that pair these expert voices with skincare and lifestyle creators.

Yes. A mass-market brand like NIVEA and a dermo-cosmetics lab like Eucerin don't have the same expectations. Our method adapts the tone, formats and creator profiles to each positioning, while keeping overall consistency across a group.
