How To Read A Skincare Label
Ingredient order, the one percent line, and the six claims that legally mean nothing.
Published 2026-09-08 · 9 minute read · The Gelagen Journal
An ingredient list is one of the few genuinely informative things on a skincare package, and almost nobody reads it, partly because it is printed in five point type and partly because the names look deliberately impenetrable. They are not. There are rules, and knowing four of them changes what you buy.
Rule 1: The Order Is Not Arbitrary
Ingredients are listed in descending order of concentration. The first is the most abundant and it is water in the overwhelming majority of products, listed as aqua. The first five ingredients are typically the great majority of what is in the bottle.
So when a product is sold on an ingredient that appears second from last, you are looking at a trace. It is on the label to be on the front of the box.
Rule 2: The One Percent Line
Below one percent concentration, ingredients may be listed in any order. That line is not marked, but you can find it: preservatives, fragrance and colourants are used at low concentrations, so once you see phenoxyethanol, parfum or a colour index number, everything from around there onwards is likely below one percent.
If the hero ingredient appears after that point, it is present at a trace level. Some actives genuinely work at low concentration — retinoids and certain peptides among them — but hyaluronic acid listed after the fragrance is decoration.
Rule 3: Six Words That Mean Nothing
| The word | What it actually means |
|---|---|
| Natural | Nothing. It is unregulated in most markets, and poison ivy is natural. |
| Chemical free | Nothing. Water is a chemical. Every product is chemicals. |
| Hypoallergenic | Nothing enforceable. There is no legal standard behind it. |
| Dermatologist tested | That a dermatologist was present for a test. It does not say what was tested, on how many people, or what the result was. |
| Clinically proven | Sometimes a great deal, sometimes an eight-person in-house study measuring self-reported satisfaction. The claim is only as good as the study behind it. |
| Non-comedogenic | Unregulated, and largely derived from old testing on rabbit ears at concentrations no product uses. |
Rule 4: Percentages Matter More Than Presence
Vitamin C serums are the clearest example. L-ascorbic acid has evidence behind it at around ten to twenty percent and at a low pH. A product containing a fraction of a percent, or a derivative with much thinner evidence, is a different product wearing the same word. If a brand is proud of its concentration, it prints it.
What To Look For Instead
- The active named with a percentage
- Opaque, air-tight packaging for anything unstable
- A short list, if you react easily
- Fragrance-free rather than unscented
- A period-after-opening symbol you can actually follow
- A brand that says what a product does not do
"Unscented" and "fragrance-free" are not the same thing: an unscented product may contain masking fragrance to cover the smell of its own ingredients. Fragrance is among the commonest causes of contact dermatitis, so the distinction is worth knowing.
Supplement Labels Follow The Same Logic
Everything above transfers to a supplement panel, with one addition: check the serving size before you read a single amount. A panel showing impressive figures per four capsules is not the same product as one showing them per one.
Then look for a number beside every name. A proprietary blend lists impressive ingredients and discloses the amount of none of them, which is the exact equivalent of an ingredient buried below the one percent line. We do not use one, which is why every amount on our panel is printed — including the small ones we then have to explain.
Questions
Quick Answers
Are parabens dangerous?
The regulatory consensus in major markets is that the parabens still permitted are safe at the concentrations used. The panic ran ahead of the evidence and some replacements are more irritating.
Does an expensive product have better ingredients?
Sometimes, and often you are paying for packaging, fragrance and marketing. The ingredient list is the only way to tell, which is why it is worth learning to read.
What does 'clinically proven' actually require?
Far less than it sounds. Ask how many people, over how long, measuring what, and whether the study was independent.
