Stand in front of a skincare shelf and you are reading two documents at once. One is the front of the box: a short list of confident words chosen by people whose job is to sell you the thing. The other is the ingredient panel on the back, usually in tiny type, and it is the only part of the packaging written to a legal standard. Almost everyone reads the first one. The second is where the information actually is.
This is a guide to reading the back of the box, and to knowing which words on the front are backed by an audit, which are backed by a definition, and which are backed by very little. Some of the terms in that last group are ones our own corner of the industry leans on heavily. We would rather say so than let a nice-sounding word do work it has not earned.
What the Ingredient List Actually Tells You
Every cosmetic sold in the EU has to carry a list of ingredients, written in INCI names. That is the shared international naming system that makes “Aqua” mean the same thing in Lisbon as it does in Helsinki, and it is why the panel reads like botanical Latin crossed with a chemistry exam. It is not there to intimidate you. It is there so that the same ingredient cannot hide behind fifteen different marketing names.
The order is real, for the first few lines
The Cosmetics Regulation requires the list to run in descending order of weight, measured at the point each ingredient is added to the batch. So the first name on the panel is the largest single ingredient by weight, the second is the next largest, and so on.
Then comes the caveat that changes how you should read the whole thing. Anything present at under 1% may be listed in any order, once the ingredients above 1% have been listed. Nothing on the label marks where that line falls.
Which means the top of an ingredient list is a ranking and the bottom of it is just a set. If the extract you were sold on appears twenty-second out of twenty-four, its position tells you nothing about how it compares to the one listed twenty-third. Both are somewhere under one per cent, in an order the manufacturer was free to choose.
As a rough guide rather than a rule: once you reach preservatives, pH adjusters such as citric acid or potassium hydroxide, gums and thickeners like xanthan gum, and individually named scent compounds, you are usually below the 1% line. Treat everything after that point as present, not as ranked.
A worked example
Our own Sensitive Skin Moisturiser opens with aloe leaf juice, then glycerin, then jojoba seed oil. Water appears eleventh. That is the entire point of reading the panel rather than the front: most face creams lead with Aqua, and if that matters to you, the panel is the only place that tells you. It is not a claim about performance and we are not going to dress it up as one. It is simply what the order discloses, and the order is the part you can check yourself.
The asterisks on that list, next to the aloe and the jojoba, mark ingredients from organic farming. That convention is not required by the Cosmetics Regulation — it comes from certification schemes and brands, so it is worth knowing what a given brand means by it. We explain ours, and every ingredient we use, on our ingredients page.
Three conventions people routinely misread
- Colourants can break the order. Colourants other than hair dyes may be listed in any order after the other ingredients, and a shade range may list every pigment used across the whole range with a “may contain” or a +/- symbol. So a pigment on the label might not be in the pot in your hand.
- Nano means nano. Ingredients present as nanomaterials must be followed by the word “nano” in brackets. If it is not there, they are not present in that form.
- Parfum is one word for many. More on this below, because it is the single most useful thing on the panel for reactive skin.
What “Certified” Means When It Is Real
Here is the honest reason third-party certification exists at all: neither “natural” nor “organic” has a legal definition for cosmetics in the EU. The EU organic rules cover agriculture and food, not face cream. The Cosmetics Regulation governs safety and labelling, and sets no threshold for how natural anything has to be. That gap is exactly the space private standards were built to fill.
COSMOS is the main one you will meet on European shelves. It is audited by an independent certifying body rather than declared by the brand, which is what separates it from a word on a box. The practical check in a shop takes two seconds: a genuinely certified product prints its natural-origin and organic percentages near the logo, not just the logo. If you want the longer version, we wrote up what COSMOS does and does not certify separately.
The Words That Look Like Certification and Are Not
“Natural”
On its own, meaningless as a technical claim. No legal definition, no minimum threshold in EU cosmetics law. There is an ISO guideline, ISO 16128, giving a method for calculating natural and organic content — but it is a guideline, not a certification. Nobody audits you against it. A brand can follow it carefully and honestly, and a brand can also just print the word.
“Dermatologically tested”
This one deserves more care than it usually gets, in both directions. It is not a meaningless phrase. European Commission guidance says the claim implies the product was tested on humans under the supervision of a dermatologist, that consumer self-perception surveys are not adequate support for it, and that the average consumer reasonably expects the results to have been positive and to have shown the product was well tolerated. The brand has to hold evidence for it.
What it does not tell you is the shape of that test. There is no standardised protocol, no required number of participants, no defined pass threshold, no obligation to publish anything. “Tested under a dermatologist and well tolerated by the panel” is a real statement. It is not the same statement as “suitable for your skin”, and the label cannot close that gap.
“Hypoallergenic”
Not a term with a legal threshold, but not a free-for-all either. Commission guidance says it may only be used where the product has been designed to minimise its allergenic potential, backed by robust evidence kept up to date, and that known sensitisers should be avoided entirely. The same guidance is blunt about the limit: the claim does not guarantee the absence of an allergic reaction, and the product must not give the impression that it does.
So it signals intent and evidence held by the manufacturer. It does not signal a standard you can look up, and it is not a promise about you specifically. If you have reacted to things before, the ingredient panel is more use than this word.
“Chemical-free”, and free-from claims generally
More useful than the obvious point about chemistry: EU guidance actually restricts free-from wording. “Free from parabens”, for example, should not be accepted, because it denigrates a group of legally permitted and safety-assessed ingredients. Free-from claims are considered acceptable where they support a genuine informed choice — “free from animal-derived ingredients” on a product intended for vegans. This is one of the few places where the rules push back on scaremongering rather than on brands.
“Parfum” Is the Most Important Word on the Panel
If your skin reacts and you only learn one thing here, learn this. A whole perfume composition can be listed under the single term “parfum”, or “aroma”. That one word can stand for dozens of individual scent materials, and the panel is not required to break them out.
There is an exception, and it is the useful part. Individual scent compounds that EU rules require to be declared must appear by name in the list, in addition to parfum, once they exceed 0.001% in a leave-on product or 0.01% in a rinse-off one. Those are the names that puzzle people: limonene, linalool, geraniol, citral. They are not additives sneaked in beside the fragrance — they are usually components of it, often naturally occurring in essential oils, named because they are recognised sensitisers for some people.
Labels are getting longer, and it is worth knowing why. The list of scent compounds that must be declared by name has been expanded to more than eighty entries. Products newly placed on the EU market must comply from 31 July 2026, and stock already on shelves may be sold through until 31 July 2028. So over the next couple of years you will see allergen lists grow. That is more disclosure, not more allergens. The same formula that listed two names may list six. Nothing was added to it.
One more distinction worth carrying into a shop: “fragrance-free” and “unscented” are not interchangeable. Fragrance-free is a free-from claim and has to meet the common criteria. Unscented is not defined anywhere, and a product can smell of nothing while still containing scent materials. The panel settles it. If parfum, aroma or a named scent compound is on the list, scent materials are in the bottle. Our Sensitive Skin Moisturiser is one we made fragrance-free deliberately, and its panel carries no parfum and no declared scent compounds — which is the version of that claim you can verify without trusting us.
Vegan and Cruelty-Free Are Two Different Claims
They get printed side by side so often that people read them as one idea. They answer completely different questions.
Vegan is about what is in the formula: no animal-derived ingredients. There is no EU legal definition of the term for cosmetics, so it may be a brand’s own declaration or a third-party mark, and those are not equivalent. It does at least describe something specific and checkable against the panel.
Cruelty-free is about testing, and in the EU it is close to meaningless as a differentiator, because it is the legal floor. Animal testing of cosmetic ingredients and finished products, and the sale of cosmetics tested on animals, are prohibited under the Cosmetics Regulation, with the last of those deadlines falling in March 2013. Every legally sold product on a European shelf sits under the same rule. EU guidance is explicit that a brand should not present mere compliance with minimum legal requirements as a specific benefit. So in a European shop, a cruelty-free logo separates a product from almost nothing.
The Legally Required Bits Almost Nobody Reads
These are on every compliant product, and each is a small piece of accountability.
- A responsible person, named with an address in the EU. Someone specific is legally answerable for that product.
- A batch number. This is what makes a recall or a complaint traceable to a specific production run.
- A best-before date, or an open-jar symbol. Products with a minimum durability over 30 months do not need a date. Instead they carry the open-jar symbol with a number of months — the period the product stays good after opening. “12M” means twelve months from opening, not from purchase.
- A hand-on-book symbol, meaning there is more information on an enclosed leaflet.
- A statement of what the product is for, unless that is obvious from the packaging.
If You Have Sensitive Skin and Thirty Seconds
In rough order of how much each will tell you.
- Find parfum or aroma, and look for named scent compounds after it. This is the highest-yield ten seconds on the whole panel.
- Read the first five ingredients. Those are ranked, and they are most of the formula.
- If there is a certification logo, look for the percentages beside it. A logo with no numbers is worth a second look.
- Ignore “dermatologically tested” and “hypoallergenic” as tie-breakers. Both mean something real to the manufacturer, and neither is a standard you can check.
- Patch test anyway. Nothing on any label, ours included, predicts how your skin will respond to a specific formula.
None of this makes shopping for skincare quick, and we are not going to pretend a shorter ingredient list is automatically a kinder one. What reading a label buys you is a smaller amount of guessing. The certifications are worth something because someone independent checked them. The regulated symbols are worth something because someone is accountable for them. Most of the rest of the front of the box is typography. Knowing which is which is the whole skill, and it takes about a minute to use once you have it.
