Synthetic Fragrance vs Natural Perfume: What's Really on Your Skin?
Open the ingredients list on most perfumes and you'll find one word doing an enormous amount of hiding: fragrance. Sometimes it's written as parfum. Either way, it's rarely just one thing.
Under UK and EU law, that single word can legally stand in for a mixture of hundreds of aroma chemicals, and the brand isn't required to tell you which ones. Which means a bottle can list "fragrance" and be entirely within its rights not to say another word about what's actually inside it.
We think you deserve to know what you're wearing. So here's what the word "fragrance" can be hiding, why our perfumes are made differently, and why we'd choose a botanical over a synthetic every day.
The word 'fragrance' can be hiding thousands of unlisted ingredients
The industry body that governs fragrance ingredients maintains a list of more than 3,000 substances that are permitted to sit under that one word on a label. Any combination of them can go into a product marked simply "fragrance," with no further disclosure required.
Some of those ingredients are entirely benign. Others include synthetic musks and phthalates that campaigners and researchers have raised concerns about for years, particularly around skin sensitisation and hormone disruption.
The point isn't that every synthetic fragrance is harmful. It's that you have no way of knowing, because the label doesn't tell you.
That's the opposite of how we work. Every essential oil in every ENSC perfume is named, in full, on the ingredients list. Lavender is lavender oil. Frankincense is frankincense oil. Nothing is bundled under a single catch-all word.
Natural fragrance, fragrance, and essential oils aren't the same thing
Labels use these terms as if they're interchangeable. They're not.
"Fragrance" or "parfum" almost always means synthetic — aroma molecules built in a lab, whether to imitate something found in nature or to create a scent that doesn't exist in nature at all.
"Natural fragrance" sounds reassuring but has no strict legal definition, so it can mean a genuine plant-derived blend, or it can mean a synthetic compound simply modelled on a natural one.
Essential oils, by contrast, are the real thing: pure extracts pressed or distilled directly from petals, peel, wood, resin or root, with nothing standing in for them. When we say botanical, we mean essential oils and nothing else — no fragrance blends dressed up in nicer language.
Why the same botanical perfume smells different on everyone who wears it
Synthetic fragrance is built for consistency. That's its entire design brief: smell the same on every wrist, in every climate, for years on the shelf. To do that, the molecules are engineered to resist the very things that make your skin yours — its pH, its warmth, its natural oils.
Essential oils do the opposite. Their molecules are drawn to the oils already on your skin, and they shift as your body warms them through the day. That's why a botanical perfume never smells quite the same on two different people, and why it moves — top notes first, then the warmer, deeper notes emerging as the hours pass. It isn't inconsistency. It's the fragrance becoming genuinely yours, rather than sitting on top of you like a coat that never quite fits.
There's more to it than a pleasant smell
Essential oils don't just smell good. Many carry out measurable effects on the body once they're inhaled or absorbed through the skin, because the plant compounds they're made of are recognised and used by our biology in ways synthetic molecules simply aren't built to be.
Lavender is the most studied example. Inhaling it has been shown, across a considerable body of clinical research, to ease anxiety and lower stress markers — not as folklore, but as a repeatable, measurable effect. Bergamot carries similar evidence for lifting mood and calming the nervous system.
Synthetic fragrance can imitate the scent of either. It cannot replicate what happens in the body once you breathe it in, because there's no bioactive compound there to do the work — only a molecule designed to smell right and nothing more.
Yes, natural perfume fades faster — and we think that's rather the point
We'll say this plainly, because we'd rather be honest: a botanical perfume won't last on your skin the way a synthetic one does. Synthetic fixatives are built specifically to cling and project for as long as possible. Essential oils were never trying to do that.
We used to see this as something to work around. We don't any more. A fragrance that fades is a fragrance that was never trying to broadcast at you from across the room in the first place — it settles close to the skin, softens, and asks you to reapply through the day rather than marinating in one static scent from breakfast until bed.
We think of it less as a limitation and more as a small ritual: a reason to pause mid-afternoon and roll a little more Luxury No.1 onto your wrists. That's not a compromise. That's simply what happens when a scent is left to be what it is, rather than engineered to be something else.
How to tell if a perfume is genuinely natural
A few things worth checking before you buy:
- Look for the word "fragrance." If that's on the label, assume synthetic. A genuinely natural perfume will name its essential oils individually.
- Look for alcohol. Most conventional perfumes are alcohol-based, which is part of what gives synthetic fragrance its long, consistent throw. Botanical perfume oils are usually blended into a carrier oil instead.
- Expect it to change. If a fragrance smells identical from the first spray to the last trace hours later, it's very unlikely to be natural.
Where we stand
Every ENSC perfume is made from essential oils and nothing else — no synthetic fragrance, no alcohol, no undisclosed "parfum" hiding behind a single word on the bottle. What's on the label is what's in the bottle, in full.
Our Luxury No.1 Botanical Perfume Oil was the very first scent we made, back when we were still working from the kitchen table, and it remains our most-loved — Provençal lavender, frankincense and myrrh, blended exactly as it was in 2010.
Our Amber Oud Botanical Perfume Oil is warmer and more resinous, built around amber and sweet almond oil for a scent that also happens to condition the skin it sits on.
Neither is trying to be loud. Both are trying to be honestly, entirely themselves — which, we'd argue, is what a perfume was always meant to be.
