Micro Creators Are Winning Beauty: Inside Our May Global Social Index

There’s a girl on TikTok who turns charity shop hauls into runway-ready fits. She has 8,000 followers. Her comment section feels like a Reddit thread, and a brand stumbles onto her page through an algorithm rabbit hole. A goldmine of content and a highly engaged audience that refers to her as the queen of thrift.

Across the 50 beauty brands we track on Instagram and TikTok, the numbers point in one direction: influence has stopped being purely based on size. Here’s what the data says, and what brands should do about it.

Before we get into the data, this is the criteria against what we are scoring it 

The brands at the top of the index aren’t there because they have the biggest budgets but it’s a bit more nuanced than that. The index takes four criteria into account: Partnership presence, partnership power, partnership effectiveness, and earned love.

Brand Presence 

How strong is the brand’s presence across its own social channels? This considers the size of its audience and how effectively its content engages that community. A strong score means the brand has built an active and responsive social audience.

Partnership Power

How visible is the brand across the creator landscape? This considers the scale, frequency and consistency of its influencer activity. A strong score means the brand is regularly showing up in relevant social conversations through creators.

Partnership Effectiveness 

How well are those creator partnerships performing? This measures whether sponsored content is genuinely connecting with audiences and generating meaningful engagement, rather than  simply being published.

Earned Love 

How much unpaid conversation is the brand generating? This captures organic creator mentions and content, indicating whether the brand is inspiring genuine advocacy beyond formal partnerships.

Behind the four scores sit ten publicly available social performance metrics, collected through platform APIs and other accessible digital sources. These include signals such as audience size, engagement, content activity, creator mentions, posting frequency and momentum over time.

Each metric is normalised so brands of different sizes can be compared fairly, then weighted according to its relevance. The scores are refreshed monthly to show which brands are leading the conversation, gaining momentum or beginning to fall behind.

The result is one simple score that turns a wide range of public social and influencer data into a clear, comparable picture of brand influence.

La Roche-Posay took the #1 spot with an index score of 35.3, and the reason is instructive: its standout pillar was earned love – the organic, unpaid conversation a brand generates on its own merits – at 42.6, paired with strong partnership effectiveness of 33.4. Momentum and collaboration working together at scale.

Just behind it, Huda Beauty (#2) posted an earned love score of 48.0 – the single highest figure across all 50 brands. 

L’Oréal Paris (#3) led the top three on partnership power at 40.8 – the most consistent and visible creator presence among the leaders.

The pattern underneath all three is the through-line of the entire index: the brands winning on social are treating creators as long-term partners rather than relying on one-off activations. Consistency and cultural relevance have become the benchmarks – not follower counts, not reach, not a single splashy moment.

Earned Love Is the Trust Signal You Need to Sustain 

If earned love is what separates the winners, the obvious question is how brands earn it. The index makes the answer unusually visible, because it separates paid reach from organic advocacy.

• Rhode’s top ten Instagram posts in May were all unsponsored – not seeded, not briefed, just people posting because they want to.
• CÉCRED kept 86% of its posts unsponsored and still hit a 3.5% average effectiveness rate on Instagram, out-engaging brands running far larger paid programmes.

You can’t buy a column like earned love. As the name suggests, you earn your way into it, one consistent creator relationship at a time – which is exactly why it’s the hardest thing to replicate and the most valuable thing to have. This is especially true in an era where audiences are more averse to traditional advertisement and long for experiences that don’t feel manufactured. 

A Word on Micro and Nano Creators

So who is actually generating all this organic conversation? Increasingly, it’s the smallest creators on the platform.

Quick housekeeping, because the tiers matter even if they feel like a clinical way to talk about real people. Nano creators have up to 10,000 followers; micro creators sit between 10,000 and 100,000. The reason the distinction matters is simple: these creators don’t have audiences, they have communities – people who trust their opinions, know their holy grail products, and wait for the sit-down video that feels less like an ad and more like a chat with a friend.

And this tier is no longer a fringe tactic. It’s the infrastructure of the whole category:

• 63% of all brand collaborations tracked in May came from nano and micro creators 6,199 nano posts and 11,399 micro posts across the 50 brands.
• Rhode’s single best-performing Instagram post of the month came from a creator with just 13,000 followers, hitting a 12× effectiveness rate on the brand’s top Instagram posts of the month. 
• Rare Beauty’s most over-indexed posts came from accounts with under 5,000 followers.

A 13K creator out-punching a global megaphone is the entire argument in one data point. When someone with a few thousand followers recommends a product, their audience isn’t weighing it against a hundred sponsored posts that week – they’re weighing it against everything that person has ever said. That’s a fundamentally different purchase conversation than a partnership where everyone in the comments already knows it’s an ad.

Reach Is Not the Same as Influence

The instinct under the old playbook is to chase the biggest possible reach moment and reach moments do happen. CeraVe’s top TikTok collaboration pulled 50.4 million views in May, the most-watched post of the month. This was done in collaboration with basketball legend Carmelo Anthony. The partnership was rooted in an anti-dandruff campaign in order to reach a large chunk of Americans that struggle with scalp sensitivities. 

The brands consistently topping the effectiveness rankings – engagement measured against the audience that actually saw it were building something smaller and more systematic. And the macro tier still earns its place when it’s done with the same rigour: La Roche-Posay led mega and macro efficacy at 2.29%, with Elemis (1.91%) and YSL Beauty (1.86%) close behind, and NARS, COSRX and Huda Beauty all clearing 1.6%. 

Growth Follows the Ecosystem, Not the Feed

The same logic shows up in where audiences are actually growing. Follower gains across the tracked brands were broadly flat on Instagram last month as the platform matures, while TikTok told a more dynamic story.

The standout performers on both platforms were La Roche-Posay and Rhode – and the index is clear on why: the brands posting the strongest growth combined consistent organic posting with targeted influencer seeding. Follower acquisition is increasingly tied to creator-ecosystem activity rather than brand-owned content alone.

What Comes Next

The shift has already happened. The question now is depth, not direction.

The next phase moves brands beyond creator-as-spokesperson toward creator-as-collaborator – co-developing products, sitting in on campaign strategy, being credited as genuine contributors rather than distribution channels. The creator-to-business-owner pipeline that F1 drivers recently made famous with their own brand ventures is now filtering down to creators with four-figure follower counts who’ve built loyal enough communities to launch things of their own.

For brands, this is genuinely good news. The data describes a higher-trust, higher-engagement channel that much of the industry is still treating like a smaller, cheaper version of the old model which means there’s real headroom for anyone willing to do it properly. Hand over a tight, prescriptive brief and a hyper-engaged community tunes out instantly; flip the brief into a conversation and earn your brand’s place in your consumers heart.
