The lab coat lie

The lab coat lie

Authority bias is our tendency to attribute greater accuracy to the opinion of an authority figure — not because the content is correct, but simply because of who said it. We trust the person in the white coat, the “expert”, the pharmacist who repeats their title 3 times in a 30-second ad video.

This isn’t a character flaw. This has been our wiring for most of human history. Obeying authority has meant survival. Village elder said the berry was poisonous? You didn’t eat it. Chief said the river was unsafe? You didn’t cross it . That instinct kept us alive.

But in modern life, this instinct may misfire. And the skincare industry has built an empire on it.

The Milgram experiment

In the early 1960s, Yale psychologist Stanley Milgram proved just how far this bias goes.

Volunteers were told to administer electric shocks to another person (an actor, though they didn’t know it). The shocks started mild at 15 volts. Then they increased to 30, 60, and so on. When the shocks climbed all the way up to 450 volts, the system displayed warnings like “Danger: severe shock”.

The actor screamed. Begged. Fell silent. Despite this, more than 65% of participants went all the way to what they thought were lethal shock. Why? Because a man in a lab coat told them to.
Let that sink in. Ordinary people were willing to potentially kill another human being – not because they were sadists, simply because authority instructed them to. The lab coat alone overrode their conscience.

Now tell me: How hard do you think it is to sell you a €90 moisturizer by putting a woman in a white coat next to it?

The skincare edition: how brands weaponise your bias

The beauty industry has studied this playbook meticulously.
Let’s break down the strategies:

1. The lab coat as a prop
CeraVe doesn’t just tell you their cream works. They show you someone in a lab coat. The coat signifies professionalism, expertise, authority. Your brain processes the visual cue and thinks: A professional trusts this product. Therefore, I should too.
But here’s the question they’re banking on you not asking: Did that person actually test the product? Did they conduct a peer-reviewed study? Or did they get paid €€€ to stand in front of a camera for a few hours?

2. The “I’m a pharmacist” repetition tactic
Pharmacists are trusted healthcare professionals. In Europe, pharmacies are considered “trusted health and beauty destinations”. In some countries, people are more likely to go to their pharmacy for skin conditions than a doctor. Brands know this. So they find one pharmacist – often with minimal training in cosmetic formulation or dermatology – and put them on every piece of marketing material. They repeat “I’m a pharmacist” like a mantra.
The implied message? This person knows skin.
But here’s the uncomfortable truth: A pharmacist’s expertise is primarily in medications, drug interactions, and dispensing prescriptions – not cosmetic chemistry or formulation, not long-term skin barrier function, not the nuanced difference between a humectant and an emollient. But authority bias doesn’t care about nuance. It just sees the title.

3. The dermatologist-as-influencer pipeline
This one is newer and more insidious. Dermatologists are now influencers. They’re gaining huge followings on TikTok and Instagram as people turn to them for skin health advice. And many of those dermatologists? They’re affiliated with brands. They’re paid consultants. They’re launching their own product lines.
This isn’t inherently evil. Some derm-founded brands produce genuinely good products. But the bias it exploits is undeniable: We trust the “doctor” label so completely that we rarely pause to ask if a recommendation is science-backed or financially backed.

The data: Your bias, quantified

Let’s have a look at the numbers.

According to Euromonitor International’s 2025 Voice of the Consumer: Beauty Survey, 26% of European respondents used a pharma or dermocosmetic product without consulting a healthcare professional – up from 23% in 2023.
In other words: People are buying products positioned as “medical-grade” or “dermatologist-level” without a single conversation with an actual medical professional.

But wait, it gets worse!
In a separate consumer survey in Italy, France, Germany, and the UK, 17% said that “derma or doctor-founded products and brands” specifically appeal to them. Not “products suggested by my actual dermatologist”. Not “products that have published clinical results”. Products founded by someone with a title. The title alone moves units.

Here’s the kicker. According to a Kenvue survey of 500 pharmacists across five European countries, 23% don’t feel confident advising on skin problems. Almost one in four pharmacists – the very people brands are putting on pedestals in their ads – admit they’re not sure about skin. But you won’t see that in the marketing. You’ll see the 77% who are confident. You’ll see the white coat, the “pharmacist approved” sticker. And your authority bias will do the rest.

Consumers are waking up (but not fast enough)

There’s some good news. Some consumers are starting to see through the BS. A recent survey of 300 beauty consumers found that:

・Only 24% of consumers fully trust brand self-promotion about “beauty tech” [].
・56% say “controlled human clinical test results” build the most trust – not brand claims, not influencer raves, not white coats.
・70% demand brands clearly label core ingredient concentrations.
・68% believe “lab data doesn’t equal real-world results”.

The modern consumer is evolving. The “ingredient person” is now the “evidence chain person”: ingredient → mechanism → target → formulation → proof.
Unfortunately, that’s only some consumers, the ones who are paying attention and read blogs like this one. The vast majority are still clicking “add to cart” as they see the lab coat and hear “I’m a pharmacist”.

How to defy authority bias

Let’s be clear: we’re not saying all experts are frauds. We’re not saying dermatologists know nothing. We’re not saying every product with a white coat in the ad is garbage. Instead, or position is clear: blind trust in authority is not a substitute for critical thinking.

Here’s how to fight back:

/ Separate the title from the evidence
Ask yourself: What specifically does this person’s expertise cover? A PhD in biochemistry might be relevant. A pharmacist license? Partially relevant, but not comprehensive. A “skin expert” with no credentials? That’s just a salesperson with better lighting.

Pause before you trust the uniform
That lab coat in the ad? It’s a costume. That person might be a real pharmacist, a real dermatologist, or an actor in a rented coat. The visual cue is designed to trigger your authority bias before your rational brain can engage. Notice it and name it, then decide.

Listen to your own skin, not the algorithm
The most radical act in modern beauty is simple: pause, reflect, and listen to what your own skin actually needs. Consult your doctor! Not the chatbot or the pharmacist or the TikTok dermatologist with a brand deal. Your skin is an organ, not a problem to be solved by the next purchase. It doesn’t need a robot or a white coat to tell it what to do. It needs you to pay attention.
