Turn over any cream or shampoo and you meet a wall of tiny text: Latin words, chemical-sounding names, a list that seems designed to be unread. It looks alarming, but it follows simple rules. By the end of this guide you'll know what the INCI list is, how to read it, and the few things worth a second look.
What INCI is and why the order matters
INCI stands for the International Nomenclature of Cosmetic Ingredients. It's a shared naming system, so the same ingredient looks the same on a pack in Berlin, São Paulo or Seoul. That's why the names are in Latin or English rather than your own language — it's consistency, not secrecy.
The most useful rule: ingredients are listed by concentration, from most to least. So the first few names make up the bulk of the product. There's one catch — once you get below roughly 1%, brands can list the remaining ingredients in any order. That's why a fragrance or a preservative can sit near the end even though it's there on purpose.
- Aqua (water) is first on most lotions, gels and shampoos — completely normal, not a sign of "watered down".
- The top three or four names tell you what the product mostly is.
- Everything after the ~1% line is real but minor; order there means little.
A quick way to use this without reading every word: check the top of the list to see what the product mostly is, then glance at the tail for the few things people most often ask about. Everything in between is usually doing quiet, useful work.
Long Latin names are usually plants
A long, unfamiliar name is not automatically a "chemical" in the scary sense. Many of them are plant-derived ingredients written in botanical Latin. Once you recognise the pattern, the list gets much friendlier.
There's even a structure to these botanical names: the plant in Latin, then the part used, then what it is. So Helianthus Annuus Seed Oil is simply sunflower seed oil, and Cocos Nucifera Oil is coconut oil. Once you spot the words Oil, Butter or Extract on the end, you can usually guess the rest.
- Butyrospermum Parkii — shea butter.
- Simmondsia Chinensis — jojoba (seed oil).
- Aloe Barbadensis — aloe vera.
- Tocopherol — vitamin E, often there as an antioxidant.
The flip side is also true: a short, "natural"-looking word isn't automatically gentle, and a long word isn't automatically harsh. A name's length tells you nothing about how it behaves on skin. If the marketing on the front leans hard on the word "natural", it's worth reading our piece on what "natural" on a pack really means.
What to scan for, and what to scroll past
You don't need to decode every line. A few categories are worth a glance, mostly because they're the ones people most often want to know about:
- Parfum / Fragrance. This single word can stand for a blend of many scent compounds. EU labels also spell out specific fragrance allergens (such as Limonene, Linalool or Citronellol) at the end of the list. If you have sensitive skin, this is the area to check.
- Preservatives. Names like Phenoxyethanol, Sodium Benzoate or Benzyl Alcohol keep a water-based product from growing mould and bacteria. A product with water in it needs preservation — their presence is expected, not a red flag in itself.
- Colourants and the "+/-" symbol. In makeup you'll see CI numbers (Colour Index, e.g. CI 77491 for an iron oxide). A +/- before a list means "may contain" — these shades are used across a product range, so not every one is in the tube you're holding.
And the big reassurance: a long list is not automatically worse. A simple oil might have five lines; a well-formulated moisturiser might have thirty, many of them water, plant oils and stabilisers doing useful work. Length is not a quality score — and a shorter list isn't automatically purer, it just means fewer ingredients.
How Mira reads the INCI list for you
This is exactly the kind of decoding Mira does in seconds. Scan a cosmetic's barcode and Mira reads its INCI list, matches each ingredient against its ontology, and highlights ones it considers worth a closer look — so a Butyrospermum Parkii isn't mistaken for something exotic, and an ingredient some people prefer to check on doesn't hide near the bottom. When Mira marks an ingredient as higher-risk, that's Mira's opinion about that single ingredient to help you decide — not a verdict that the product is bad, and not a medical claim.
Each product gets a transparency score from 0 to 100. This is Mira's own method — a way of reading the label to help you choose — and it isn't endorsed or approved by any health authority. It's an opinion about the product on its own, not a judgement of your health or a promise about it: how a product actually affects you depends on how much and how often you use it, on your skin, and on the rest of your routine. So treat the score as a useful starting point, not the last word. Mira stays independent: no paid placements, no brand ads, and the database keeps improving as the community scans and corrects products over time. The more people read labels this way, the better the picture gets for everyone.
One habit to take into the shop
Next time you pick up a product, read just the first three ingredients and then jump to the very end for Parfum and any allergens. Those two spots — the start and the tail — tell you most of what the label is actually saying, in about ten seconds and without a drop of panic.
