Spend ten minutes in a beauty aisle and you will be surrounded by products that are ‘clean’, ‘non-toxic’, ‘natural’ and ‘free from’ things you may never have heard of. Almost none of these claims are regulated. Here’s how to navigate the noise.
The Most Useful Word in Beauty Marketing
‘Clean’ is doing extraordinary work in the contemporary beauty market. It simultaneously evokes purity, health, environmental responsibility, ethical production, and an implicit contrast with the presumably dirty alternatives on the shelf beside it. It is also, in almost every jurisdiction where cosmetics are sold, entirely undefined.
There is no legal or regulatory definition of ‘clean beauty’ in the United Kingdom, the European Union, or the United States. No independent body certifies products as ‘clean’. No minimum standard must be met before a brand affixes the word to its packaging, website, or social media content. A product can be called clean if it contains any ingredient, in any concentration, produced by any means, at any environmental cost, as long as the company selling it decides to call it that.
This is not a minor quibble. The clean beauty market was valued at approximately $7.4 billion globally in 2023 and is projected to reach $14 billion by 2028. Consumers are making purchasing decisions, often at significant price premiums, based on a term that has no consistent meaning.
The Fear Economy
Clean beauty did not emerge in a vacuum. It developed, in significant part, from a culture of ingredient fear that grew alongside increasing consumer interest in what products actually contain. The ‘chemicals are bad’ narrative that underpins much clean beauty marketing trades on a fundamental misunderstanding: everything is a chemical, including water, and toxicity is always a question of dose and context, not of whether something has a scientific name.
The ingredients most frequently demonised in clean beauty discourse (parabens, sulphates, mineral oil, synthetic fragrance, phenoxyethanol) have been studied extensively by cosmetic safety regulators including the EU’s Scientific Committee on Consumer Safety (SCCS). In the concentrations used in cosmetic products, none of these ingredients has been found to present a risk to human health. The paraben scare, in particular, is a case study in how preliminary research can be amplified by advocacy campaigns into consumer panic: a 2004 study that detected parabens in breast tumour tissue was never replicated, did not demonstrate causation, and the concentrations detected were far below those that would be expected to cause harm, according to subsequent analysis.
This does not mean that all cosmetic ingredients are safe for all people. Some individuals do have genuine sensitivities to synthetic fragrance, certain preservatives or other compounds. Individual reactions are real. But the ‘clean’ label does not identify these individuals or protect them, because ‘clean’ products frequently contain ingredients (essential oils, natural fragrances, plant extracts) that are among the most common causes of cosmetic contact dermatitis.
“Natural does not mean safe. Synthetic does not mean dangerous. The most allergenic ingredients in cosmetics are often plant-derived.”
The Problem with ‘Free From’
A related tactic is the ‘free from’ claim, products marketed as being without specific ingredients, with the clear implication that those ingredients are harmful. ‘Paraben-free’, ‘sulphate-free’, ‘mineral oil-free’, ‘silicone-free’: each of these claims implies that the omitted ingredient was undesirable.
In some cases, the omitted ingredient is replaced with an alternative that is less well-studied, less stable, or more likely to cause sensitisation. Parabens, for example, are among the most thoroughly studied cosmetic preservatives available and are effective at very low concentrations. Many of the preservatives used as ‘paraben-free’ alternatives have a less comprehensive safety record and some, including certain natural preservative systems, are associated with higher rates of skin reactions.
The ‘free from’ marketing strategy also systematically ignores the role of concentration. Mineral oil, for example, is one of the most inert and well-tolerated skincare ingredients available; it is used in paediatric skincare and by dermatologists specifically because of its safety profile. Its ‘clean beauty’ reputation as a problematic ingredient is entirely disconnected from the scientific literature.
What Certification Actually Means
In the absence of a regulated definition of ‘clean’, third-party certifications offer more meaningful signals, but require some interpretation.
Certifications worth understanding:
- COSMOS Organic / COSMOS Natural (certified by the Soil Association in the UK): a rigorous standard that specifies the percentage of ingredients that must be from natural or organic origin, prohibits certain synthetic ingredients, and includes environmental and ethical production criteria. This is one of the more credible independent certifications available in the UK market.
- Leaping Bunny / PETA cruelty-free: certifies that no animal testing has been conducted on the product or its ingredients. This is a meaningful, independently verified claim, unlike the unregulated ‘cruelty-free’ label that brands can self-apply.
- EWG Verified (Environmental Working Group, primarily US): rates ingredients on a hazard scale and certifies products that meet certain criteria. The EWG’s methodology is contested by toxicologists, who argue that it conflates hazard (the potential for harm at any dose) with risk (the actual likelihood of harm at the doses used in products). It is more precautionary than scientifically rigorous.
- EU Regulation (EC) No 1223/2009: not a certification but a framework. Products sold in the EU and UK must comply with regulations that prohibit or restrict over 1,300 ingredients. The UK has maintained equivalent standards post-Brexit. This baseline is considerably more protective than US regulations, which prohibit fewer than 30 cosmetic ingredients.
What to Actually Look For
For consumers who want to make informed choices without navigating a minefield of unregulated marketing claims, a few practical principles apply.
First, focus on what the product contains rather than what it claims to be. The INCI (International Nomenclature of Cosmetic Ingredients) list is a legal requirement in the UK and EU, and reading it, or using reference tools such as the CosDNA database or INCI Decoder, gives considerably more information than any front-of-pack claim.
Second, be sceptical of fear-based marketing. If a brand is primarily telling you what it does not contain rather than what it does, ask what the omitted ingredients were replaced with and why.
Third, consider purpose over provenance. The most important questions about a skincare product are whether it is formulated to do what it claims, whether the active ingredients are present in effective concentrations, and whether it suits your skin type, not whether it can be described as ‘clean’ by a definition that no one has agreed upon. The clean beauty movement has done some genuine good: it has increased consumer interest in ingredient transparency and pushed brands to provide more information about their formulations. But the label itself, without independent verification and clear standards, is primarily a marketing tool. Knowing that is the most useful thing any consumer can take into a beauty aisle.
