Clean beauty has a $10 billion problem: nobody agrees on what it means.
In most markets, including the United States, “clean” is not a regulated claim for cosmetics. Any brand can call its product clean, non-toxic, or free-from without meeting any independently audited standard. This regulatory vacuum created a market segment that grew explosively — and, in growing without standards, created both genuine innovation and significant consumer confusion.
The real clean beauty players
At one end of the spectrum: brands that have built genuine credibility through formulation transparency. Ilia publishes its full ingredient lists with explanations. Drunk Elephant famously maintains a list of six ingredient categories it never uses, explained clearly and consistently. True Botanicals has third-party efficacy testing.
These brands earn the “clean” positioning because they demonstrate what they actually put in and why, and subject their claims to scrutiny. Their customers trust them because the trust is justified by evidence.
At the other end: brands that adopt clean packaging aesthetics, use “free-from” language, and rely on consumer pattern-matching (green branding + plant imagery + natural-sounding ingredient names = clean) without changing their formulas substantively. Some of these brands are benign but misleading. Others are explicitly opportunistic.
The free-from problem
The “free-from” marketing format — no parabens, no sulfates, no silicones — has become the dominant clean beauty signal. It’s also frequently scientifically misleading.
Parabens, the most commonly avoided ingredient class, have been used in cosmetics for decades at concentrations that extensive research has found safe. The concern originated in a 2004 study that found traces of parabens in breast tissue — the study’s methodology was subsequently criticized, and regulatory agencies in the US, EU, and Japan have reviewed the data and maintained that parabens are safe at cosmetic use levels.
None of this means brands are wrong to avoid parabens if their customers prefer it. But it does mean the implication that paraben-free products are safer is not supported by current scientific consensus. Marketing that suggests otherwise is, at minimum, misleading.
How retailers have stepped in
Facing regulatory inaction, major retailers have created their own clean standards. Sephora’s “Clean at Sephora” program maintains a list of over 50 ingredients that products must avoid to carry the designation. Ulta Beauty has a similar framework. Target has “Target Clean.”
These programs are imperfect — the lists differ, the audit processes vary in rigor, and the retailer’s financial relationship with the brands it certifies creates potential conflicts. But they provide consumers with a concrete reference point within specific retail environments.
Buying a product labeled “Clean at Sephora” means something specific and documented, even if “clean” in general means nothing. That incremental clarity is valuable.
What scientific clean beauty looks like
The next evolution of clean beauty is not cleaner marketing — it’s scientifically documented transparency. The European cosmetics regulatory framework, among the world’s most rigorous, is pushing toward evidence-based claims and efficacy demonstration. This pressure will eventually reach other markets.
For brands, the strategic position to occupy is not “clean” (undefined) but “transparent and effective” (documented). The consumer who knows enough to ask “what does clean actually mean here?” is the consumer whose loyalty is most durable — and the most skeptical about vague claims.
That consumer is growing as a share of the beauty market. The brands that have built evidence-based credibility now are positioned well for the moment when “clean” without substance stops working as a selling point.
