Sensitive Skin Glossary: The Label Words That Matter
Share
If your skin reacts to things, you've probably already learned that the front of a jar is written for a different person than you are.
The front is for someone browsing. It says gentle, pure, clean, for sensitive skin. The back is for someone who has been burned before literally, in some cases and needs to know exactly what's going on their face at 10pm.
This is a glossary for that second person. What these words legally mean, what they don't, and which ones are quietly doing the opposite of what you'd assume.
Part one: words with no legal definition
These are not lies. They're just not claims. Nobody is checking them, because there's nothing to check against.
Clean. There's no regulatory definition of clean beauty. None. Each brand or more often, each retailer writes its own list of excluded ingredients and calls compliance with that list "clean." The lists don't agree with each other. A product can be clean at one store and not at the next without a single molecule changing.
Natural. Also undefined for cosmetics. Poison ivy is natural. Formaldehyde occurs naturally. The word describes an origin story, not a safety profile, and for reactive skin specifically it predicts almost nothing.
Non-toxic. Chemical free. Pure. Gentle. Non irritating. All undefined, all unenforced. Water is a chemical. "Gentle" is a description of an average person's experience, which may or may not include yours.
Hypoallergenic. This is the one that surprises people. There is no federal standard behind it. A brand can print it because their formula excludes a few common allergens, or because they patch tested it well, or because it sounded reassuring in a meeting. All three uses are equally legal, and the label looks identical in every case.
Dermatologist tested. A dermatologist was involved. That's the claim. It doesn't say how many people were tested, what the protocol was, what the results were, or whether anyone reacted. "Dermatologist recommended" is usually a survey.
Non comedogenic. No standardized test is required to say it. The original testing method involved rabbit ears, and it correlates loosely at best with whether a product will break out a human. Useful as a signal of intent. Not a promise.
Sensitive skin tested. Suitable for sensitive skin. No standard exists for what "sensitive skin" means clinically, so there's no standard for testing against it either.
Part two: words that actually mean something
Here's where the label gets useful.
The INCI list. This is the real label the ingredient list in standardized international nomenclature. Ingredients appear in descending order of concentration until you hit 1%. Below that, order is arbitrary and the brand can arrange them however it likes. Learning to spot roughly where that 1% line falls is the single most useful skill on this whole page, and I'll come back to it.
Fragrance / parfum. One word standing in for a formula that may contain dozens of individual materials, protected as trade secret. Fragrance is among the most common triggers for allergic contact dermatitis from cosmetics, which makes it the most consequential word on the label for reactive skin and the least specific.
Where you are changes what you're told. The EU and UK have long required specific fragrance allergens to be named individually on the label above set thresholds, and that list has expanded well past its original 26 entries. Canada is phasing in something similar.
In the US, the 2022 cosmetics law directed the FDA to write a fragrance allergen disclosure rule, and as of this writing the proposed rule has been delayed repeatedly and still isn't in effect. So a US label can legally tell you less than a European one for the same formula.
Fragrance free. Should mean no added fragrance materials. Not legally defined, but it's a specific enough claim that it's rarely abused outright the abuse happens by omission, which brings us to part three.
Named allergens. If you see limonene, linalool, citral, geraniol, eugenol, or coumarin on an ingredient list, you're looking at specific fragrance components that regulators elsewhere consider worth naming. They show up in essential oils as often as in synthetic fragrance. If you've reacted before and never known to what, these are worth learning by sight.
USDA Organic. COSMOS. Ecocert. Real certifications with real thresholds and real audits behind them. Note that "made with organic ingredients" is a weaker tier than a certification seal, and that "organic" says nothing whatsoever about whether something will irritate you.
Patch tested / HRIPT. A Human Repeat Insult Patch Test is an actual protocol a panel of subjects, repeated exposure, then a challenge phase and a brand naming it is telling you something concrete. "Patch tested" with no protocol named is closer to part one. pH. Healthy skin surface sits acidic, roughly 4.5 to 5.5. If a brand gives you a number, that's real information. "pH balanced" with no number is not.
Part three: words that mean the opposite of what you'd assume
Unscented. This is the big one. Unscented means the product doesn't smell like anything. It does not mean fragrance free a masking fragrance is sometimes added specifically to cover the smell of the raw materials underneath. If fragrance is your trigger, unscented is not the word you're looking for. Fragrance-free is.
Alcohol-free. Refers to ethanol, the drying kind. Acetyl, cetearyl and stearyl alcohol are fatty alcohols waxy, emollient, and generally well tolerated. A product can be full of them and still say alcohol-free, correctly.
Essential oil based. Naturally scented. Aromatherapy blend. Natural fragrance is still fragrance, and some of the most common sensitizers on that named-allergen list are exactly what makes essential oils smell the way they do. A product can be fragrance-free in spirit and still hand your skin a citrus oil.
Preservative-free. In an anhydrous product, fine. In anything containing water, it means either an unconventional preservation system or a microbiology problem waiting for a warm bathroom. Preservatives exist because the alternative is worse.
Free from / no nasties. The free from list is a marketing selection, not a safety audit and sometimes it makes things worse. The best documented example: when the industry moved away from parabens, some formulas moved toward preservatives that turned out to be considerably more sensitizing, and dermatologists spent years treating a wave of contact allergy that the older preservative wasn't causing. Removing an ingredient people fear is not the same as removing the thing that was hurting them.
How to actually read the back of a jar
1. Find the 1% line. Look for the preservative, the gum (xanthan, sclerotium), tocopherol, or fragrance. Everything at or after that point is present in trace amounts. If a hero ingredient sits down there, it's a garnish, not a formula.
2. Read for your triggers first, not the marketing second. If you know you react to a specific material, that search takes ten seconds and settles the question before any front of jar language gets a vote.
3. Watch where fragrance sits. It's usually listed near the end regardless of amount, so position tells you less here than elsewhere. Presence is the signal.
4. Count the actives. A long list of interesting-sounding actives at trace concentration is a worse bet for reactive skin than a short list at a meaningful one.
5. Keep your own list. Genuinely a note on your phone with the INCI names that have burned you. It will outperform every certification seal on the market, because it's the only one calibrated to you.
About our own label
Our jar says Natural.
By the standard of this post, that phrase is doing exactly what I've spent fifteen hundred words warning you about: it's undefined, unenforced, and it feels like a safety claim without being one. I'd rather name that myself than have you catch it.
What I can point you to instead is the ingredient list, which is where the actual answer lives, and the fact that we'd rather tell you what a product feels like than tell you it's guaranteed to suit you. Nothing is guaranteed to suit you. Anyone promising otherwise is guessing about a face they've never met.
Where we land
Reactive skin makes you a close reader, and close readers are the toughest customers in this category. Good. The industry has earned that.
Learn the six or seven words that carry real information INCI order, fragrance, fragrance-free versus unscented, the named allergens, an actual pH number and most of the front-of jar vocabulary stops working on you. That's not cynicism. It's just knowing which half of the package was written for you.
