If you've ever stood in a beauty aisle or scrolled through a brand's website trying to work out whether a product is genuinely clean — you're not alone, and you're not imagining the confusion. The term "clean beauty" has no legal definition in the UK or the EU. No regulatory body oversees it. No standard exists for what qualifies.
Any brand can put "clean" on their packaging today, regardless of what's inside the bottle.
How "clean" became a marketing term rather than a standard
The clean beauty movement began with a legitimate concern — that certain synthetic ingredients in cosmetics may have long-term health implications, and that consumers deserve transparency about what they're applying to their skin every day.
That concern is reasonable. But as the market grew, "clean" became a commercial opportunity rather than a commitment. Brands began using it selectively — removing one or two controversial ingredients while retaining others, or simply using natural-sounding language and earthy packaging to imply purity without evidence.
The result is a market where "clean" can mean almost anything — or nothing at all.
What clean beauty claims actually tell you
"Free from parabens" tells you one preservative system wasn't used — but not what was used instead, or whether the alternative is better. "No nasties" is entirely subjective. "Natural" is unregulated. "Non-toxic" has no agreed definition in cosmetics.
Even certifications vary enormously. Some organic certifications require only a small percentage of ingredients to be certified organic. Others have rigorous standards. Without knowing which certification a brand holds and what it actually requires, the logo tells you very little.
The ingredients worth actually paying attention to
What to genuinely look for — and avoid
Fragrance / Parfum. One of the most common causes of skin sensitisation. Listed as a single ingredient but can contain dozens of undisclosed compounds. Worth avoiding for sensitive or reactive skin.
Silicones. Not harmful, but can create a barrier that prevents active ingredients from penetrating effectively. Common fillers in premium-priced products that deliver surface feel rather than genuine results.
PEGs (Polyethylene glycols). Used as penetration enhancers and emulsifiers. The concern is not toxicity at standard concentrations but the potential for enhancing the absorption of other, less desirable ingredients.
Synthetic fragrance compounds. Certain musks and fragrance chemicals have raised questions around hormone disruption. The science is not conclusive, but avoidance is a reasonable precaution for daily-use products.
High concentrations of alcohol. Used as a preservative and texture agent, but can disrupt the skin barrier over time in formulations where it features prominently.
What genuinely clean formulation looks like
A brand that is serious about clean formulation will be transparent about every ingredient and why it's there. They will be able to explain not just what they've excluded, but what they've included and how each ingredient contributes to the product's performance.
They won't rely on filler ingredients — water, cheap emollients, silicones — to bulk out a formula while active ingredients appear in negligible concentrations. And they won't use "clean" as a shorthand for effective, because they understand that clean and effective are not the same claim.
How to read a label properly
Ingredients are listed in descending order of concentration. The first five ingredients typically make up the majority of a formula. If those first five are largely water, glycerin, and emollients with active ingredients appearing far down the list — the product is mostly filler with a marketing story built around a small percentage of interesting ingredients.
Look for active ingredients appearing in the first half of the list. Look for a brand that explains its formulation choices rather than simply listing certifications. And treat "clean" as the starting point for a question — not the answer to one.
At Intrinsic Skincare, we don't use "clean" as a marketing claim. We use it as a commitment — to never including ingredients we wouldn't be comfortable putting on our own skin, and to formulating without fillers so that every ingredient listed is there because it genuinely contributes to your skin's health and results. We publish our full ingredient lists and we'll always explain why each one is included.
