Vibes Are Not Evidence: The Problem With "Clean" Skincare
"Clean" is one of the most powerful words in personal care marketing right now. It sits on packaging, anchors brand identities, fills Instagram bios, and commands a price premium from consumers who believe it means something specific about what they're putting on their skin.
The problem is that nobody — not regulators, not industry bodies, not the brands using it — has agreed on what it actually means.
That ambiguity isn't just a communications challenge. In 2026, it's becoming a significant legal and commercial liability. And the wave of litigation building around "clean," "natural," "plant-based," and related terms is revealing something important about how health and wellness brands think about the relationship between language and evidence — or, more often, don't.
The word that means everything and nothing
Walk into any pharmacy or beauty retailer and count how many products use "clean" as a positioning claim. You'll lose count quickly. But ask those brands what "clean" means and you'll get wildly different answers — no parabens, no sulphates, no synthetic fragrances, no ingredients derived from petrochemicals, no PFAS, no anything-the-brand-has-decided-is-undesirable-this-year.
There is no regulatory definition of "clean" when it comes to cosmetics. BCLP In Australia, cosmetic product claims are primarily overseen by the ACCC under Australian Consumer Law, which requires that advertising is not false, misleading, or deceptive — but provides no specific definition of what "clean" means or what a brand must demonstrate to use it. In the US, the FDA has no definition either. What both frameworks share is a requirement that any claim — including implied ones — must not mislead a reasonable consumer. And "clean," used without clear definition, almost always creates implied promises that the product can't necessarily keep.
This is where the legal exposure begins.
The litigation wave is here
For years, "clean" and "natural" claims existed in a kind of enforcement twilight zone — technically unsubstantiated, practically unchallenged. That twilight zone is closing fast.
A class action filed in California in December 2025 against Supergoop! alleges that products marketed as "100% Mineral" create a misleading impression that the entire formula is mineral-based, when the products allegedly contain non-mineral or synthetically processed ingredients. Cosmetics Design The underlying legal concept — the "net impression" a claim creates in the mind of a reasonable consumer — is the same one being deployed across dozens of similar cases.
Neutrogena is currently defending a class action alleging its makeup remover towelettes were falsely advertised as "plant-based." Clinique has faced suit over "probiotic technology" claims on skincare products. Class action activity around functional claims including "natural," "clean," and "wholesome" has surged, with plaintiffs increasingly arguing that these terms are misleading without adequate substantiation.

The pattern across all of these cases is consistent: a brand uses evocative language that resonates powerfully with consumers, without establishing either a clear definition of what that language means or evidence that the product meets it. Plaintiff attorneys then argue — often successfully — that the net impression created by the claim was false or misleading, regardless of whether any individual ingredient claim was technically accurate.
The risk of regulatory enforcement is comparatively low, but the risk for private and costly litigation is high, as plaintiffs pursue copycat claims on a classwide basis.

The ANZ picture: a different set of watchdogs
For brands operating in Australia, the regulatory picture for cosmetics involves three distinct authorities — the TGA, AICIS, and the ACCC — and understanding which one governs your claims is not always obvious.
The ACCC is the primary regulator for cosmetic product safety and claims, administering Australian Consumer Law, which requires that advertising about cosmetics is not false, misleading, or deceptive. Therapeutic Goods Administration The TGA enters the picture the moment a cosmetic product makes a therapeutic claim — something that changes how the body works, rather than simply how it looks or smells. That boundary matters enormously for personal care brands.
"Moisturises and softens skin" is a cosmetic claim. "Repairs the skin barrier" starts to look therapeutic. "Clinically proven to reduce inflammation" almost certainly is. The language that sounds most impressive to consumers — and most compelling to marketing teams — tends to be precisely the language that triggers the higher regulatory burden. In Australia, that means TGA registration, full efficacy evidence, and compliance with the Therapeutic Goods Advertising Code.
There is no Australian regulatory definition of "natural," "clean," or "organic" for cosmetics, just as there isn't in the US. Using the term "natural" incorrectly or without proper definition for therapeutic goods would be a breach of the Therapeutic Goods Advertising Code, and for cosmetics, people can report non-compliant advertising to the ACCC. Skincarebusinessfoundations The practical implication for brands is that these terms carry real consumer expectations — and therefore real exposure under misleading conduct provisions — even without a specific statutory definition.
The smarter alternative is closer than it looks
The irony of this situation is that the underlying consumer insight driving "clean" skincare is entirely legitimate. People want to know what's in their products. They want transparency about ingredients. They're sceptical of synthetic chemicals with unpronounceable names. They've watched enough documentaries to be wary of what gets absorbed through skin. Those concerns are real and the market that's formed around them is real.
The problem isn't the consumer insight. It's the shortcut brands have taken in responding to it — reaching for a single, emotionally resonant word instead of doing the harder work of actually communicating what makes their product different and why it matters.
The brands building durable positions in this space are doing something more specific. Instead of "clean," they're saying "formulated without X, Y, and Z — here's why those ingredients concern us and here's what we use instead." Instead of "natural," they're specifying the origin and processing of their key ingredients. Instead of "plant-based," they're telling you which plants, at what concentration, with what evidence of effect.
There is a technical framework that can help here — ISO 16128, the international standard for calculating the natural and organic content of cosmetic ingredients and finished products. It assigns a naturalness index to each ingredient, allowing brands to make specific, calculated claims like "formulated with 97% natural origin ingredients." It's a more defensible position than a bare "natural" claim, and it reflects genuine formulation intent.
But it's worth understanding what ISO 16128 is and isn't. The standard explicitly does not address product communication — claims and labelling — human safety, environmental safety, or regulatory requirements applicable for cosmetics. ISO It is a calculation methodology, not a certification, not a law, and not a claims framework on its own. It is not legally binding, requires no third-party certification, and there is no body checking whether a brand's calculations are correct. Intertek Brands self-declare — which means a product can carry "95% natural origin ingredients according to ISO 16128" and still contain controversial preservatives or synthetic ingredients in the remaining percentage, with no independent verification that the number is accurate.
Third-party certification schemes like COSMOS, NATRUE, or Ecocert go considerably further — audited standards, prohibited ingredient lists, GMO restrictions, and independent sign-off. For brands serious about building a credible natural positioning, ISO 16128 is a useful calculation tool and a reasonable starting point for ingredient transparency. It is not the finish line. Used selectively or without that context, it can actually deepen the consumer trust problem it appears to solve.
That specificity — whether through ISO 16128 calculations, third-party certification, or clearly defined ingredient exclusion lists — is harder to build than a single word on a label. It requires more from the formulation team, the regulatory team, and the marketing team simultaneously. But it creates something that "clean" never will: a claim that's defined, defensible, and genuinely differentiating. A competitor can put "clean" on their label tomorrow. They can't replicate a specific, substantiated formulation story.
The question worth asking before the next brief
Before any new product or campaign goes to market with "clean," "natural," "plant-based," or similar language, the question worth sitting with is this: if a plaintiff attorney asked us to define that term precisely, specify what evidence supports it, and explain the net impression a reasonable consumer would take from it — could we answer comfortably?
If the answer is anything less than a confident yes, the claim isn't ready. And in 2026, with litigation in this space accelerating on both sides of the Pacific, the cost of getting that wrong is no longer hypothetical.
Vibes, it turns out, are not evidence. But specific, substantiated claims can be both compelling and defensible. That combination is rarer than it should be — and for brands willing to build it properly, it's a genuine competitive advantage.
At Parallaxis, we help brands understand where their current claim language sits — what's defensible, what's exposed, and what would make it stronger. If "clean" is doing a lot of work in your marketing right now, it might be worth a conversation.
