“Consumer-perceived” results: what the small print means

The big print says “visibly smoother skin in 7 days*”. The tiny print at the bottom of the box says “*consumer-perceived results, 40 women”. That little asterisk changes what the claim means. Here’s how to translate it, and why it matters more for some claims than others.

What “consumer-perceived” actually means

It means the result came from people’s own opinions. Participants used the product, then answered a questionnaire about what they noticed. Nobody pointed a device at their skin, and no trained grader scored it.

You’ll see the same idea under different names:

• “consumer-perceived” or “consumer-perception study”
• “self-assessment” or “self-evaluation”
• “based on a consumer panel” or “users agreed”
• “% of women said…”

Every one of these tells you the number is a count of opinions, not a measurement. That’s not a trick in itself. We’ve covered how perception tests and instrument tests work in our piece on “9 out of 10 agreed”. This article is about the small print itself: what to do when you see it, and why your own skin is a less reliable witness than it feels.

Feeling claims vs change claims

The key is to match the evidence to the claim. The UK’s advertising code body, the Committee of Advertising Practice, which publishes some of the clearest public advice on cosmetic claims, sorts them roughly into two piles.

Sensory claims are about how the product feels or how you feel using it: “skin feels smoother”, “looks fresher”, “for more radiant-looking skin”. The guidance calls these low risk and says they can be supported by consumer perception tests. That makes sense. If the claim is about a feeling, asking people how it felt is the right test.

Claims about change are different. Anything that suggests the skin itself changed, or that the effect builds over time, needs “a much higher level of evidence”, in the guidance’s words. And it names a specific trap: marketers should “avoid confusing readers by trying to support an objective claim using subjective feedback.” Its example is “82% decrease in wrinkles*… *based on 52 customer responses.” A wrinkle decrease sounds like a measurement. It was really a poll.

So when you read the asterisk, go back to the big print and ask: is this a claim about a feeling, or a claim about my skin?

Why your skin is a tricky witness

You’d think people would know whether their own skin got better. Often they do. But a few well-known forces push self-reports around.

Expectation

If you expect something to work, you tend to feel that it does. A 2021 randomized trial in Germany showed this nicely in adults with eczema (atopic dermatitis, the itchy, inflamed rash). Researchers triggered itch with a small histamine skin prick. People who openly received an infusion of salt water, described to them as an anti-itch drug and paired with a learning step to build the expectation, reported a bigger drop in itch than people who received the real antihistamine hidden, without being told.

The objective sign, the size of the raised bump, didn’t follow the same pattern: the salt-water group and the hidden-drug group were no different. Expectation moved the feeling more than it moved the skin. A glossy box, a nice scent and the word “clinical” all set expectations too.

The question itself

What people report depends heavily on what they’re asked. Canada’s industry body, Ad Standards, publishes guidelines for surveys used to back comparative ad claims. They warn against “leading or loaded questions”, questions “respondents are unlikely or unable to answer accurately”, and questions set up in an order that can bias the answers. They also say opinion research should allow a “don’t know/no opinion” answer.

Those guidelines are written for claims that compare one product with another, but the logic carries over. “Does your skin feel more hydrated?” asked right after applying a cream invites a yes. “Is your skin less dry after four weeks than with your usual product?” is harder to agree with, and more useful.

Who was asked, and what they knew

The same guidelines say survey data must come from “the pertinent population”: the kind of people the claim is about. A test on 40 women in their 30s doesn’t tell you much about a teenager’s oily skin or your grandfather’s winter-dry shins. For claims of better results or preferred taste against a competitor, Ad Standards also expects product tests to be done blind, so people don’t know which brand they’re using. A consumer panel that knows exactly whose product it’s testing isn’t blind.

What the Canadian rules say

No Canadian law defines “consumer-perceived”. The general rule from the Competition Bureau covers it. Under the Competition Act, a company can’t make a claim about a product’s performance or effectiveness unless it’s based on an “adequate and proper test” done before the claim is made. The Bureau says such a test should be done under controlled conditions, “eliminate subjectivity as much as possible”, reflect real-world use and support the general impression the ad creates.

A questionnaire is subjective by design. That doesn’t rule it out for a sensory claim. But if the overall impression of an ad is “this cream changes your skin”, a stack of self-reports is shaky ground.

How to read the asterisk in the aisle

When you spot “consumer-perceived” or “self-assessed”, run through these:

• Look at the verb. “Felt”, “noticed” and “said” are opinion words. “Reduced”, “increased” and “repaired” are change words. Change words backed by opinions are the mismatch to watch for.
• Find the number of people. Forty people rating a cream is a small sample of opinions.
• Check the timing. “Immediately after application” measures how a cream feels going on. “After 4 weeks” is at least asking about something that lasted.
• Look for a second kind of evidence. Does the box also mention a device reading or a grader? If both agree, good. If the survey stands alone, read it as “people liked it”.
• Notice who was tested. Is it people like you, with your skin concern?

When perception is exactly what you want

Don’t throw these results out. For some things, your opinion is the only measure that counts: whether a cream feels greasy, whether it absorbs, whether a cleanser leaves you tight, whether you’d happily use it every day. A moisturizer you hate the feel of won’t get used, and an unused moisturizer does nothing. Perception tests are good at answering “will I like this?”.

They’re just not good at answering “will this change my skin?”. And if you’re dealing with a real skin problem, like eczema that keeps flaring or dryness that cracks and bleeds, a satisfaction percentage isn’t the evidence to lean on. If it isn’t better after two weeks, see your doctor or pharmacist.

What to remember: “consumer-perceived” means the number counts opinions. That’s fair support for claims about feel and weak support for claims about change, because expectations and the wording of the questions shape what people report. Match the big print to the small print, and you’ll know how much weight the asterisk can carry.
