You're standing in the aisle. One bottle says "natural." The other says "clean." A third says "dermatologist-tested." They all cost more than the generic next to them. And you have no idea which one is telling the truth.

That confusion is by design. The European Commission's 2021 market study found that 42% of green marketing claims online were exaggerated, false, or deceptive.1 This article breaks down the five most common greenwashing red flags and what actually signals a safer product.

What is greenwashing, exactly?

Greenwashing is when a company markets a product as safer, cleaner, or more environmentally sound than it truly is — typically using vague label claims that evoke safety without meeting any regulatory standard. In March 2026, the EU began requiring implementation of the Greenwashing Directive, which will require proof for environmental and safety claims starting September 2026. The US has no equivalent federal law.

Red flag #1: "Natural"

What you think it means: Made from plants, not synthetic chemicals. Minimally processed. Safe.

What it actually means: Legally, in the US? Nothing.

The FDA has never formally defined "natural" for personal care or cleaning products. There's no checklist a brand must pass. A product with synthetic preservatives, lab-made fragrance compounds, and petrochemical derivatives can legally call itself "100% natural" — and many do.2

Lead is technically natural. Arsenic is natural. The word alone tells you nothing about safety.

What to look for instead: Third-party certifications with public standards — EWG Verified, MADE SAFE, and USDA Organic maintain prohibited substance lists, require testing, and are independently audited.

Red flag #2: "Clean"

What you think it means: Free of harmful chemicals. Safe for sensitive skin.

What it actually means: Less than "natural." Possibly nothing.

"Clean" is not defined by any regulatory body. Retailers like Sephora and Credo have created their own standards — and these differ significantly from each other. When a brand puts "clean" on its own label without referencing a specific standard, it's self-certifying with no third-party review.

What to look for instead: Ask which specific "clean" standard applies and where it's published. Credo's prohibited list, Sephora's Fragrance-Free policy, and EWG's Verified program are actual standards.

Red flag #3: "Dermatologist-tested"

What you think it means: Doctors reviewed it and found it safe. Clinical validation.

What it actually means: At least one dermatologist applied the product to skin and noted no adverse reaction. That's it.

The FTC has no rule on how "dermatologist-tested" claims are substantiated. In practice, a brand typically pays one or a few dermatologists for a short patch test. "Tested" is not "approved." It doesn't mean safe for all skin types. It doesn't mean the formula was evaluated for ingredient safety.3

What to look for instead: "Dermatologist-recommended" with named practitioners and disclosed methodology is stronger. Peer-reviewed studies are meaningful.

Red flag #4: "Free from [X]"

What you think it means: A product without a known bad ingredient is safer.

What it actually means: Possibly safer on that one dimension — but "free from" says nothing about what replaced it.

"Paraben-free" became a major selling point after studies raised concerns about parabens' estrogen-mimicking properties. Many brands removed parabens and replaced them with methylisothiazolinone (MI) — a preservative associated with significantly higher rates of contact dermatitis than the parabens it replaced. You removed one concern and added another. The label doesn't tell you that.

Red flag #5: Vague environmental claims

What you think it means: Sustainable, eco-friendly, planet-safe.

What it actually means: Unverified. The EU Greenwashing Directive specifically targets terms like "carbon neutral," "eco-friendly," and "sustainable" that aren't backed by proof.

What to look for instead: B Corp certification, ECOCERT, Leaping Bunny (for cruelty-free), and Carbon Neutral certifications with disclosed methodology carry actual meaning. Vague "eco" packaging without specifics is just aesthetics.

The shortcut: certifications worth trusting

  • EWG Verified — no chemicals of concern, full disclosure required, independently verified
  • MADE SAFE — screens against 6,500+ known harmful chemicals
  • USDA Certified Organic — regulated standard with audits; applies to plant-derived ingredients
  • Leaping Bunny — cruelty-free certification with supplier audits
  • Certified B Corp — overall social and environmental accountability

The bottom line

The most protective habit: skip the front label entirely and read the ingredient list. Check EWG Skin Deep for any product you're uncertain about. Marketing words are art. Ingredient lists are fact.
