A (long) Introduction
I’m not going to make you sit through a 300-400 word intro and teaser before actually saying what the ingredient is.
80% of all skincare contains fragrance.
Actually, more than 80%, and definitely much more than enough to make you question every single future product purchase.
Because believe it or not, if you’ve ever had a bad reaction – no matter how mild – to a product, there’s about a 50% chance (verified stat, btw) that fragrance was responsible.
I will, however, take my time with this introduction. Because this “ingredient” is something that has managed to nuke my skin on more than one occasion – and I say that as someone that’s tested over $60,000 worth of skin products as part of my job – and that’s not even counting the products I’ve spent my own money on.
This “nukage” has also (likely) happened while using various different chemicals under this one name (“fragrance”) – but we will never know that for sure because the law is such as it is. More on that later on in the post.
It took over 30 hours to put my thoughts regarding this post together and go through the dozens of relevant studies, a good bit of which I’ll be referencing here.
The issue with these studies is that, to the everyday consumer – myself included, they are very, very far from optimal to get educated from a consumer standpoint, lengthy, and just overall a pain in the a**.
That’s why this post exists.
My girlfriend has just had the worst outbreak of her life. At 31 years old. Thanks to a mask that contained “fragrance” (again, what that “fragrance” is – who knows).
And it took us over 3 weeks, 4 different derms (and way too much money) to figure this out.
🟠 In case it is still not clear – and for the purposes of SEO (is SEO even a thing anymore with all the AI stuff?), the topic of today’s post is fragrance in skincare; why it’s such a common ingredient in products, what kind of impact it may have on your skin and overall health, how to know which fragrance ingredients are “good”, and, spoiler – but I doubt you’ll be surprised, why I personally avoid it like the plague – most of the times.
So if you have the next 8 minutes or so to spare, you will have absorbed, what is – in my mind, the most up-to-date, actionable, and broken-down-into-bite-sized-pieces-that-actually-matter-for-the-everyday-consumer post about fragrance in skincare in 2026.
With This Post I’m Trying Something New

I mentioned just above that it’s broken down in bite-sized pieces, and I mean that literally. For the next few articles – and longer, hopefully, if it receives good feedback – I’ll be breaking up posts into more-but-shorter sections, so that they literally.
Two reasons:
1. Most of our brains are just too used to getting everything served in under a minute-long shortform videos, that longform content is, as much as it pains me to say it, on the verge of dying out (at least, for consumer-led niches like skincare)
2. There’s about a 75-80% chance that you are reading this through a mobile device. I realized that, while skin nerds like myself (and many of you) will easily go through a 4,000+ word article, the fact of the matter is that most people want the actionable stuff, hopefully with proof and studies, and what exactly to do. With this format, you’re getting both.
fragrance is in almost everything skincare. It’s in most things that claim not to have it. And the regulatory body responsible for protecting you is openly telling you this is legal.
In short, we are all f*cked and sentenced to a lifetime of mediocre-at-best skin.
Well…maybe not.
One thing that’s for sure is that there are way too many problems (for us consumers), even at present, surrounding this ingredient.
The Scale Of The Problem
Skip to The Big Picture if you don’t care about the tech-y stuff / blog updates.
Fragrance chemicals are present in more than 95% of personal care products.
Not 95% of cheap drugstore products.
Not 95% of heavily marketed luxury brands.
95% of all personal care products.
In skincare specifically, the best study I could find looked at allergens as a whole – with fragrance being by far the most common culprit. That number was just slightly lower, at 88%, but still scary enough to make studying what you actually put – most often, daily – on your face, a pretty good idea.
*The 88% figure comes from a 2017 Northwestern University study that looked specifically at best-selling moisturizers – i.e. the kind that are on the top every “derm-approved” list – and found that 88% of them contained at least one known allergen, with fragrance being the most common culprit across the entire dataset.
I could not find an independent study that looked at whether the same holds true across all product categories – likely because one does not exist (the scope of such a study would just be too complex, long, and/or expensive to fund). Seeing as how fragrance serves the same commercial purpose across all product types, the assumption is not a stretch. That doesn’t make it right or wrong, but I have the compulsive nature to clarify things like these.
But here’s where it gets interesting.
The figure that was actually the most shocking discovery and should make anyone do a double take on every future skincare purchase: 45% of the products in that same study that were explicitly labelled fragrance-free still tested positive for at least one fragrance or botanical cross-reactor.
QUOTE: “For products with a claim of “fragrance free,” 18 (45%) had at least 1 fragrance cross-reactor or botanical ingredient. Products without any ingredients in the NACDG (median, $0.83; IQR, $0.47-$1.69) were not statistically more expensive per ounce than products with 1 or more allergens (median, $0.60; IQR, $0.35-$1.06).”
Let me make this perfectly clear: the label says one thing while the formula contains something else in almost half the cases.
And this isn’t an accident.
It’s very rare that “best-selling” in the category of anything comes from small indie brands. I of course don’t have access to the actual products used in these studies and this is just my personal take, so you should take it as such:
Most of the big companies regularly pumping out best sellers have R&D departments, regulatory teams, and access to, potentially, decades of formulation data. They know exactly what’s in their products.
The ones I feel worst for are the people who went fragrance-free because they are sensitive and reactive to fragrance products and skin may have already been struggling.
Someone can do everything “right”. Read the label. And still get duped. More on that in a sec.
“Oh, it hasn’t happened to me yet, I’m fine.”
Fair, but can you really be sure:
Fragrance-induced contact dermatitis is one of the most commonly misdiagnosed skin conditions.
(this is, by the way, the same thing that nuked my gf’s skin)
At least half of all fragrance-allergic individuals never connect their symptoms to fragrance at all — they’ll blame their skin type, their diet, their water. Partly because the ingredient list doesn’t tell them what’s actually in the product.
“…in absolute numbers, contact allergy to fragrances is common and constitutes the second most frequent cause of allergic contact dermatitis in our environment. At least half of all fragrance-allergic individuals do not associate their symptoms with contact sensitization to these substances. The exact frequency of allergy to fragrances in the general population is difficult to determine.”
The Legal Loophole
When you see “fragrance” or “parfum” on an ingredient list, you’re not just reading an ingredient.
You’re reading a ingredient, with potentially thousands of chemicals behind it.
The term “fragrance” is essentially a legal placeholder.
Under the Fair Packaging and Labeling Act, fragrance formulas are classified as trade secrets, meaning brands are under zero obligation to tell you what’s actually in it.
The International Fragrance Association, also known as IFRA, maintains a public library of every ingredient that can legally hide behind that word.
This is not some small-scale project ran by a few people. It is the global representative body of the entire fragrance industry, that’s been around for over 50 years.
As of their 2025 update, that list sits at 3,691 ingredients.
Let that sit for a second.
Thousands of ingredients can be named just under that one word.
The EU, which is considered the strictest cosmetics regulator in the world, currently requires disclosure of only 80 such ingredients.
80 out of 3,691.
Once again, please let that thought marinade.
And that is the most optimistic scenario, because I’d bet that even this doesn’t cover the whole story:
The 80 EU allergens aren’t “fragrance ingredients” in the same category as the 3,691 IFRA ingredients. They’re specifically substances with known allergenic potential that, when present above a concentration threshold, must be individually named on the label.
They’re largely derived from fragrance components, but it’s two different lists being compared.
What the comparison actually means: out of everything that can hide behind the word “fragrance,” the EU – the strictest cosmetics regulator in the world – only forces brands to individually name just 80 specific substances on the label. The other 3,600+ can still sit behind that one word.
Good news (well, you can be the judge of that): the 80 figure is a more than 3X improvement up from just a few years ago. That number used to be 24 up until 2023.
So when you’re reading an ingredient list, thinking you know what you’re putting on your skin – not really. Most of us have zero clue.
You’re reading a curated summary.
Because the full version isn’t available to the average consumer.
That’s not an accident or an oversight.
It’s literally written into the law.
But what about natural fragrance?
Where I Buy My Skincare From
mentioning where I buy my skincare.
So Then, Natural Fragrance Must be Better…Right?
So at this point, a reasonable person thinks: okay, I’ll just switch to natural fragrance. Problem solved.
It isn’t.
“Natural fragrance” enjoys the exact same legal loophole.
It’s still one word (well, two words) “natural fragrance”. Still a “trade secret”.
And still zero obligation to tell you what’s behind it. The only difference is the marketing.
Because the thing about natural is – poison ivy is natural. So is poison oak. Arsenic is natural.
Naturalness has never had anything to do with skin safety, and fragrance is a perfect example of why.
Some of the most potent allergens found in fragrance come directly from essential oils. Most reading this post have come across terms like linalool, limonene, eugenol – these are naturally derived fragrance components that appear on the EU’s own allergen disclosure list. Not because they’re synthetic. But because they cause reactions.
The “natural” label is a positioning decision, not a safety guarantee. And the brands selling it know that too.
It’s All Out In The Open. It Must Mean It’s Fine.
Yep.
The FDA will actually confirm this. Their own website says that even products marketed as “unscented” may contain fragrance — added specifically to mask the smell of other ingredients, just at a low enough concentration that you don’t notice it.
Even some products labeled “unscented” may contain fragrance ingredients. This is because the manufacturer may add just enough fragrance to mask the unpleasant smell of other ingredients, without giving the product a noticeable scent.
Just on the FDA site, this isn’t just explained on one article (granted, the second one I found deals specifically with disposable wipes – but that would make it worse in my mind, given that we literally rub those on ourselves)
Wipes are sometimes labeled as scented, unscented, or fragrance-free. FDA doesn’t have regulations governing the use of these terms. But cosmetic labeling is required to be truthful and not misleading.
Typically, the word “unscented” on a cosmetic label means that the product doesn’t have a noticeable scent. But it may actually contain “masking” fragrance ingredients to hide the smell of ingredients whose scent may be unpleasant.
So to recap: fragrance is in almost everything. It’s in most things that claim not to have it. And the regulatory body responsible for protecting you is openly telling you this is legal.
And we haven’t even gotten to the loophole the brands love to abuse yet.
Why Brands Do It Anyway
If fragrance is this problematic, why is it then in everything?
Two reasons.
The first is practical. Raw cosmetic ingredients can smell awful. Peptides, fatty acids, certain actives are (very) unpleasant on their own.
Fragrance masks that. It makes a formula that would otherwise smell like feet and ham (and I’m being very generous with the wording) – smell and be perceived like a luxury product.
In a lot of the cases, it’s also cheaper to add fragrance than to reformulate.
The second reason is psychological. The moment you apply a product and it smells good, your brain interprets that as the product working. It feels premium. It feels effective. That sensory hit in the first three seconds of application drives repurchase more reliably than the actual ingredients do.
So fragrance solves two problems for brands simultaneously — it covers up the smell of cheap raw materials, and it manufactures a perception of quality that has nothing to do with what the formula actually does for your skin.
This is a deliberate commercial decision. One that, in most cases, doesn’t put our skin as the priority.
We’ve all got so used to having fragranced products (on top of, as mentioned before, not knowing half the time if it even has fragrance), that all of this has become too normalized.
And normalized means invisible. Which is exactly how the big players and big brands want it.
Because a consumer who’s used to something doesn’t question it.
They just keep buying and the cycle stays intact.
And yet, nobody had to hide anything. Everything written in this post is publicly available information.
The problem is, being confused is what makes a very profitable consumer. And in today’s day and age most people aren’t reading ingredient lists. The bigger problem is that even the ones who are, don’t know what half the names mean.
Anyways I have a 5-day free email training where I teach skincare obsessives and [glowing skin fanatics] about all of this.
You can put your email here and I’ll send you a short email every day for the next 5 days what I learned in the last 10 years about skincare, as someone that’s been obsessed with this topic, as well as worked with some of the biggest brands and cosmetics manufacturers in the world, and managed over 1,000 influencers with “perfect” skin.

And by interesting, I mean crazy. Seriously, we need to bring more awareness to this.
Seriously, most of these are not cool. We need better transparency and education in these circles.

The Practical Exit
Here’s where I want to slow down and actually be useful to you.
Because knowing fragrance is a problem is one thing. Being able to spot it on a label while you’re standing in a store or scrolling through a product page — that’s what actually changes anything.
The first thing to know: fragrance doesn’t always show up as “fragrance” or “parfum.”
Sometimes it does. But a lot of the time it’s hiding in plain sight as individual chemical names that look completely innocent to anyone who hasn’t gone down this rabbit hole.
Names like linalool. Limonene. Eugenol. Citronellol. Geraniol. Cinnamal. Coumarin. Benzyl Alcohol. Citral. Farnesol.
These aren’t bonus actives doing something for your skin. They’re fragrance components — most of them in fact naturally derived — that brands can list individually instead of writing “fragrance” and technically stay within the rules.
Some of them show up in products specifically marketed for sensitive skin. Some are in baby products.
When you see them, now you know what you’re actually looking at.
The most practical thing I can tell you: go to INCI Decoder or download Skincarisma.
Paste your ingredient list. Let it do the work. I’d genuinely recommend doing this with at least one product you currently use and consider “safe” — not to stress you out, but because seeing it once makes this whole post real in a way that reading it doesn’t.
You might be surprised. Most people are.
The situation is getting better. Just in the last 10 or so years, a lot of the fragrance ingredients that have come out have actually been much more milder than your standard linalool, etc.
But, products that have been on the market for longer than those 10 years – you would be surprised how many companies did not update their structures, because it’s “cheaper that way” or a product that has generated hundreds of millions of $ in sales
