How clean is “clean beauty,” exactly? The honest answer is that no one knows, because no one in North America regulates the term, and brands have used the gap to mean whatever happens to flatter their formulation choices that quarter.
This is not a niche complaint. It is a structural problem in a category that, according to Statista, generated more than $11 billion in U.S. sales in 2024. A category that large with no shared definition is a category where consumer trust gets exploited routinely, even by brands that mean well.
What does “clean” mean to whom?
Sephora’s Clean at Sephora program excludes about fifty ingredients from products carrying its seal. Credo Beauty’s “Dirty List” excludes around 2,700. Whole Foods’ beauty standards are different again. Ulta’s Conscious Beauty hub uses its own framework. Each list reflects the retailer’s risk tolerance, marketing positioning, and the practical realities of what their assortment can support.
None of the lists are wrong, exactly. They are also not consistent, which means a product labelled “clean” at one retailer may not qualify at another. The buyer is left to either trust the seal in front of them or do the homework themselves, which most do not have time for.
The Environmental Working Group’s Skin Deep database, often cited as a neutral reference, has its own methodological issues, including a tendency to flag ingredients based on association rather than dose, and a hazard scoring system that some toxicologists have criticized as alarmist. The Personal Care Products Council, an industry group, dismisses Skin Deep entirely. The truth, as so often, sits between the two camps and is not particularly satisfying as a sound bite.
What does the science actually support?
A handful of clean-beauty claims hold up under scrutiny. Avoiding fragrance allergens makes dermatological sense for the meaningful percentage of the population that reacts to them. Phasing out certain UV filters that show endocrine activity at high doses is reasonable, even if the actual exposure from skincare is small. Reducing ethanolamines and certain preservatives with sensitization potential is a defensible choice for sensitive skin.
Many other clean-beauty claims do not hold up. The campaign against parabens has been substantially undermined by the regulatory toxicology, which finds the doses used in cosmetics far below any threshold of biological concern. The blanket suspicion of synthetic ingredients ignores that many natural ingredients, essential oils, certain plant extracts, are far more allergenic than their synthetic counterparts. The fear of “chemicals” as a category is incoherent because everything in skincare, including water, is a chemical.
The honest summary is that clean beauty contains some real wisdom, some real overreach, and a significant amount of marketing that has nothing to do with either.
What does credible curation look like?
The retailers and brand curators who have built durable reputations in this category share a few traits.
They publish their criteria. The curation philosophy is on the website, with an explicit list of what is excluded and why. The reasoning is grounded in something more specific than “natural is better.”
They include performance claims, not just exclusions. A serum that is free of fragrance and parabens but does not address the skin concern it is sold for is not actually a useful product. Credible curators emphasize results alongside ingredient profile.
They distinguish between cosmetic risks and aesthetic preferences. There is a real difference between excluding an ingredient with documented sensitization data and excluding an ingredient because the founder finds it inelegant. The honest curators say which is which.
For a working example, customers can discover clean beauty at Living Beauty, where the brand assortment, including Biologique Recherche, Augustinus Bader, Agent Nateur, Codex Beauty Labs, and others, is built around clinical efficacy and clean formulation working together rather than treated as competing values. The curation is opinionated in the right direction, with explicit reasoning for inclusion that does not collapse into vague natural-is-better marketing.
The trade-offs no one wants to discuss
Removing every potentially worrisome ingredient from a formulation has real costs. Preservatives are not optional in water-containing products, and the alternatives to synthetic preservatives are sometimes more allergenic, less effective, or both. Fragrance-free products often substitute essential oils that produce the same allergic reactions in some users. Replacing a synthetic emulsifier with a “natural” one can reduce stability and shelf life significantly.
The brand that removes the most ingredients is not automatically the brand with the best product. Sometimes it is the brand that has accepted the most trade-offs in performance to satisfy a marketing position. The buyer who values both efficacy and clean formulation has to look at the actual formulation rather than the front-of-package claims, which requires more work than most marketing assumes.
Sustainability claims complicate the picture further. A glass jar is not automatically more sustainable than a plastic one once shipping weight enters the equation. Refillable systems are sometimes the genuine improvement, sometimes a marketing exercise. Carbon-offset programs vary in rigor. The same selectivity that applies to ingredient claims applies to packaging claims, and the same skepticism is warranted.
What about Europe versus North America?
The European Union’s cosmetics regulation, REACH, prohibits or restricts more than 1,300 ingredients. The FDA, by comparison, restricts about eleven. This gap is real and meaningful. European-made cosmetics are operating under stricter rules by default, which is part of why French and Swiss skincare brands often have an easier time with clean-beauty positioning. They have already removed the contested ingredients because their home market required it.
This is also why some American clean-beauty brands look impressive on paper but are simply meeting standards that European brands have met for years without making it the marketing message. Buyers paying attention to clean beauty should weight the EU formulation standard as part of the analysis. A French or German prestige skincare brand operating to its home market’s standards is, in many cases, already further along on the cleanness axis than the American clean-beauty movement is asking for.
The bottom line
Clean beauty as a movement has done some good. It has pressured the industry to remove genuinely problematic ingredients, raised awareness of fragrance sensitization, and given dermatologically vulnerable consumers a vocabulary to ask for what they need. It has also generated a lot of bad science, fear-based marketing, and inconsistent labelling that confuses more than it clarifies.
The smart way to engage with the category is selectively. Trust curators who publish their reasoning. Read ingredient lists when the claim matters. Recognize that fragrance-free, EU-compliant, dermatologist-tested formulations are often closer to the clean-beauty ideal than products with the loudest clean-beauty marketing. And accept that the honest version of clean beauty is more nuanced and less Instagrammable than the simplified version, which is exactly why it is harder to sell.
