Influence agency for beauty & cosmetic brands
A beauty brand cannot be sold the same way as a bag or a pair of sneakers. Personalised, meaningful support.









The Midnight Agency
Midnight Agency is a boutique digital influencer agency. We operate in sectors where image drives sales, and beauty has been part of our focus from the very beginning.
Our team manages influencer campaigns across Instagram, TikTok and YouTube: talent selection, negotiation, briefing, content approval, and performance tracking. You have a single point of contact from the very first conversation through to the end-of-campaign report.
Our services of influence
Influence Strategy
We map your competitive landscape, identify the key prescriber circles in your category (skinfluencers, pharmacist-creators, MUAs, beauty therapists, ingredient-focused accounts) and define measurable objectives: awareness among a specific target, traffic to a product page, sell-out at point of sale, ambassador recruitment.
Influencer Campaign Management
We manage campaigns from A to Z: creator sourcing, audience vetting (engagement, fake followers, geo, age), negotiation, contracts, product shipping, briefing, monitoring, and content approval.
In the beauty sector, two points are systematically checked:
Claims: compliance with European cosmetics regulations (e.g. prohibition of claims such as “treats eczema”), with briefs validated by your regulatory team.
Transparency: clearly visible commercial disclosure (French law of 9 June 2023) and “Retouched images” disclaimer when body or skin has been altered — verified both before and after publication.
Content Creation
Beauty content that converts is demonstrative. Real-time application, texture, 8-hour wear, before/after footage filmed over several weeks, comparison with the product the person used before.
We produce these formats with you: feed posts, stories, reels, TikTok videos, and UGC content repurposable for paid advertising. Every deliverable adheres to your brand guidelines and approved claims. The best-performing content is then repurposed into ads, extending the lifespan of a campaign well beyond its initial publication window.
Analysis and reporting
We track reach, engagement, clicks, codes used and attributed sales, campaign by campaign and creator by creator. You know which profile drove volume, which drove basket value, and which cost a lot for nothing.
Monthly reports include a content analysis (which angle worked, which product was most organically picked up) and recommendations for the next wave. For a launch, we systematically compare results against the objectives set in the brief.
Our methodology
Analysis of your product range, hero products, brand messaging, and current social presence. We also look at what creators are already saying about you without being paid — this is often the best starting point for a campaign.
From this, we define measurable objectives and an influencer strategy built together with you.
Our sourcing process is based on both quantitative and qualitative criteria. Beyond audience size, we examine recent history: a beauty creator who has featured thirty brands in a year will struggle to make the thirty-first one stick. We favour profiles who post selectively, but whose every recommendation carries real weight.
Nano, micro, macro: the mix depends on your objective. Nano creators generate social proof at scale and reusable content. Macro creators build brand awareness. The two are rarely combined by chance.
We handle all negotiations and contracts, including exclusivity and image rights.
Each creator receives a detailed brief: key messages, approved claims, featured products, legal disclosures, and what is off-limits. Within that framework, they retain their editorial freedom — because a scripted beauty review is spotted within three seconds and simply doesn't convert.
We support the production process, approve content before publication, and align the timing with your key commercial moments.
Real-time monitoring throughout the campaign, with mid-course adjustments if early content underperforms. A full end-of-campaign report is provided: dashboards, KPI analysis, content assets to repurpose for your ads, and concrete recommendations for what comes next.

Types of Beauty Influencer Campaigns
Product Launch
A launch plays out over three weeks. We orchestrate the build-up: an early send to a select few, a teasing phase, a coordinated reveal on launch day, followed by a broader wave of creators to sustain momentum while interest is still at its peak.
This is the most demanding format in terms of coordination, and the one where a scheduling slip costs the most.
Seeding & Product Gifting
Large-scale product seeding is designed to build social proof and grow your UGC content library. Publication is not guaranteed, the cost per piece of content is low, and the volume matters for an emerging brand.
We select the profiles, manage the shipping logistics, and measure the actual return rate rather than simply counting the number of parcels sent.
Long-term brand ambassadors
Three posts spread over six months by the same creator carry more weight than a single post from three different creators. Repetition builds credibility, and in skincare and beauty, credibility drives purchase.
We build these relationships over time: multi-month contracts, co-created content, event appearances, and sometimes product collaborations.
Engagement and conversion
Named promo codes, tracked links, affiliate programs, redirects to your product pages or your retailers. We select profiles whose communities actually buy, not just comment, and we measure the return down to the last cent.
Why choose Midnight Agency as your beauty influencer agency?
You speak directly with the team working on your campaign — not a sales rep who hands the file off to someone else after the contract is signed.
We understand the specific constraints of the beauty industry: the claims a creator cannot make, the product shipping delays that throw an entire calendar off schedule, the difference between an audience that enjoys beauty content and one that actually buys. We turn down profiles that are not the right fit, even when they would inflate the reach figures in the report.
Finally, full budget transparency: you can see exactly what goes to creator fees and what goes to the agency.
