Written by Kershen Teo — Founder and perfumer, Prosody London.
The words fragrance, scent, and perfume are used interchangeably in everyday conversation — but they don’t mean the same thing. As a perfumer who works exclusively with botanical materials, I find these distinctions matter more than most people realise. What something is called tells you something about what’s in it, how it was made, and whether it belongs on your skin.
This piece covers all three: what scent means, what fragrance means, how perfume fits into both, and why the differences matter practically — especially if you’re trying to make more informed choices about what you wear.

What does scent mean? {#scent}
Scent is the broadest of the three terms. It refers to any smell — the natural odour given off by a living thing, an environment, or a material. It requires no human intervention. The scent of jasmine is simply what jasmine smells like. The scent of cedarwood is the natural volatile compounds released by the wood. The scent of rain on dry earth (petrichor) is a chemical process, not a manufactured one.
In everyday language, scent is used in two ways:
As a noun — referring to the smell itself: “the scent of orange blossom,” “a musky scent,” “the scent of rain.”
As a verb — meaning to detect by smell, or to add a smell to something: “scented candles,” “a scented room.”
The defining characteristic of scent in its purest sense is that it is natural and unmanipulated — it comes from the material itself. This is why perfumers working with natural ingredients talk about the scent of a material: the scent of vetiver, the scent of frankincense resin, the scent of aged oud. We’re describing the inherent smell of the raw ingredient before it becomes part of a composition. If you’re curious about how individual materials smell and behave, our guide to vetiver in perfumery is a good starting point.
Scent is also the word used to describe what animals and humans detect involuntarily — the biological signals we pick up from other people, environments, and food. In this sense it predates perfumery entirely. Scent is smell in its natural state.
What does fragrance mean? {#fragrance}
Fragrance has a more specific and more contested meaning — and understanding its ambiguity is genuinely useful if you care about what you’re putting on your skin.
In general use, fragrance means a pleasant or sweet smell. “The fragrance of roses.” Used this way it’s close to a synonym for scent, but with a connotation of pleasantness — you wouldn’t typically describe something unpleasant as a fragrance.
In its technical and regulatory sense, however, fragrance means something very different. In cosmetics and personal care product labelling, “fragrance” (or “parfum” on EU-compliant labels) is a catch-all ingredient declaration that can legally cover hundreds of individual chemical compounds — most of them synthetic — without naming them individually. This is the sense that matters when you’re reading an ingredients list.
When a product lists “fragrance” as an ingredient, it typically means a synthetic or semi-synthetic aroma compound: a blend of chemicals formulated to produce a specific smell, often derived from petrochemical processes. These may include:
Synthetic musks — compounds like Galaxolide, Tonalide, and Musk Xylene, used to extend longevity and fix other notes to skin. Several are classified as persistent environmental pollutants. Musk Xylene is designated a substance of very high concern by the European Chemicals Agency, and both Musk Xylene and Musk Ketone have been detected in human breast milk samples in independent studies. Our piece on endocrine disruptors in perfume covers this in detail.
Synthetic aroma chemicals — lab-created versions of natural materials. Synthetic jasmine approximates the smell of jasmine absolute but lacks its complexity. Synthetic oud is predominantly a burnt leather-plastic effect — recognisable, but a crude approximation of the real material. The difference becomes immediately clear if you’ve ever smelled a genuine jasmine absolute or real agarwood. We’ve covered what oud is made from in detail — it’s one of the most misrepresented ingredients in the industry.
I’ve written about what makes a quality perfume ingredient and why botanical materials perform differently to their synthetic counterparts. The jasmine example is one I return to often — natural jasmine absolute has a complexity that makes it behave almost like a living material on skin, something you can read more about in our guide to natural perfume ingredients.
Iso E Super (OTNE) — a widely used synthetic woody compound that amplifies other notes and creates a warm skin-scent effect. Under EU CLP classification it’s a listed skin sensitiser (H317), and the European Scientific Committee on Consumer Safety has recommended it for updated allergen labelling requirements. We don’t use it in any Prosody formulation. There’s a detailed breakdown of whether Iso E Super is safe on our blog.
Phthalates — plasticising chemicals sometimes used to make fragrance last longer. Linked to endocrine disruption in multiple studies, and banned in cosmetics in the EU, though still permitted in some other markets. If you’re looking for phthalate-free perfume in the UK, our blog covers what to look for on a label.
None of these will appear named on a product label. They’ll all appear as a single word: fragrance.
This is why none of our products at Prosody London list “fragrance” as an ingredient. Every compound in every formulation is named — because it’s a botanical material with a real name: bergamot essential oil, vetiver absolute, frankincense resin. That transparency is only possible because we use nothing synthetic. Browse the full natural perfume collection to see what that looks like in practice.
What does perfume mean? {#perfume}
Perfume sits between scent and fragrance — it refers to a composed, intentional smell worn on the body. The word comes from the Latin per fumum, meaning “through smoke” — a reference to the ancient practice of burning aromatic resins and woods. Frankincense, myrrh, and oud were the original perfumes; the smoke carried the scent as offering and purification.
In modern use, perfume has two meanings:
As a category — any scented product applied to the body: eau de parfum, eau de toilette, eau de cologne, extrait de parfum. All of these are perfumes in the broad sense.
As a concentration — perfume or extrait de parfum refers specifically to the highest concentration of aromatic compounds, typically 20–40% in a carrier, compared to 15–20% for eau de parfum, 8–15% for eau de toilette, and 2–4% for eau de cologne. Higher concentration generally means more intensity and longer wear — though with natural materials, the relationship is more nuanced than with synthetics.
The key thing perfume adds to the picture is composition and intention. A scent is raw. A fragrance is formulated. A perfume is both formulated and designed to be worn — it takes into account how notes develop on skin over time, and what emotional effect the composition is intended to produce.
Scent vs fragrance vs perfume — the practical difference {#practical}
If you’re trying to use these terms precisely:
Scent — any smell; the inherent odour of a material or environment. Natural by definition.
Fragrance — a formulated smell; or, on an ingredients list, a synthetic aroma compound. When it appears as an ingredient, almost always synthetic.
Perfume — a composed scented product worn on the body, or the highest concentration of such a product. Can be natural or synthetic depending on the formulation.
The confusion arises because fragrance is used both casually (meaning a pleasant smell) and technically (meaning a synthetic compound hidden behind a single ingredient declaration). The casual use is harmless. The technical use is what matters when you’re making an informed purchase.
In perfumery, we tend to say: you wear a perfume, which contains scents (natural materials) or fragrances (synthetic materials), or both. The best natural perfumes are made entirely from scent — from botanical materials with identifiable names and traceable origins.
Natural scent vs synthetic fragrance — why it matters {#natural-vs-synthetic}
This is the distinction I care most about as a practising perfumer, and the one that most directly affects what you experience wearing something.
Natural scent materials — essential oils, absolutes, resins, concretes — are complex chemical mixtures. A jasmine absolute contains over 200 identifiable compounds. Real oud can contain several hundred. That complexity is what gives natural materials their character: they smell different at different temperatures, evolve over hours on skin, and interact with individual body chemistry in ways that make them genuinely personal.
The scent of real jasmine absolute is rich, fruity, slightly indolic, and physically relaxing in a way that synthetic jasmine doesn’t approach. A synthetic jasmine smells clean and floral, but sits in the head space rather than the body. It doesn’t move.
Synthetic fragrance materials are typically single aroma chemicals or simple blends — engineered to produce a specific smell as efficiently and consistently as possible. They’re more stable, more predictable, longer-lasting, and considerably cheaper. They also carry the ingredient transparency problem: you don’t know what you’re wearing, because the label isn’t required to tell you.
The environmental picture compounds this. A 2018 study published in Science by NOAA researchers found that petrochemical-based scented products — including synthetic fragrances — generate roughly the same volume of atmospheric pollution per unit as burning petroleum for fuel. Our piece on hidden chemicals in perfume covers the wider environmental and health picture in more detail, and our post on whether perfume causes cancer addresses the health questions we get asked most often.
None of this means every synthetic material is harmful or every natural material is safe — some botanicals are sensitisers too, which is why we source to IFRA standards. If you have reactive skin, our post on natural perfume for sensitive skin covers which materials to approach with care and which tend to be well tolerated. But the transparency gap between natural and synthetic is real, and it matters when you’re choosing what to apply daily to your skin.
How to tell them apart on a label {#labels}
Reading a fragrance label is simpler than it sounds once you know what you’re looking for.
If the ingredients list says “fragrance” or “parfum” — you’re looking at a synthetic or semi-synthetic formulation. You won’t know what specific compounds are inside.
If the ingredients list names specific materials — “bergamot essential oil,” “vetiver absolute,” “cedarwood oil,” “frankincense resin” — you’re looking at a natural formulation where every ingredient is traceable and named.
Other things worth checking:
Soil Association organic standards — the benchmark for certified organic sourcing in the UK. At Prosody London we formulate closely to these standards — selecting ingredients that meet organic sourcing principles — though we are not currently Soil Association certified.
IFRA compliance — the International Fragrance Association sets usage guidelines for both natural and synthetic materials. Compliance means the formulation has been assessed for safety at the concentrations used.
“Free from” claims — phthalate-free, synthetic musk-free, allergen-free. These are worth checking against the full ingredients list rather than taking at face value.
If you’re exploring natural perfume for the first time, starting with a sample set is the most practical approach — natural fragrances perform differently on different skin chemistries, and testing before committing to a full bottle always makes sense. Our natural perfume sample set is the easiest way to do that.
Does natural scent last as long as synthetic fragrance?
Honestly — typically not in terms of raw projection. Synthetic fixatives, particularly synthetic musks, are specifically engineered to make fragrance cling to skin and fabric for extended periods. Natural resins and balsams can achieve impressive longevity, but the projection radius of a synthetic fragrance is usually wider.
What natural fragrances do instead is evolve. They wear closer to the body, which many people prefer — intimate rather than broadcasting. They change over the course of a day as different notes come forward. And they interact with skin chemistry in ways that make them genuinely individual: the same natural perfume smells different on different people in a way that most synthetic fragrances don’t.
The longevity gap has also narrowed as natural perfumers have developed better techniques for anchoring botanical notes using resinous base materials. Our guide to long-lasting natural perfumes covers the specific materials and techniques involved, and our post on why modern perfumes don’t last explains why synthetic longevity isn’t always what it seems either.
Is fragrance oil natural?
No — fragrance oil is synthetic by definition. It’s a laboratory-produced aroma compound designed to approximate the smell of a natural material, or to create a smell that doesn’t exist in nature at all. When a product says “jasmine fragrance oil,” it means a synthetic compound that smells jasmine-like, not jasmine absolute extracted from the flower.
Fragrance oils are widely used because they’re stable, cheap, consistent, and long-lasting. They’re not necessarily unsafe — many have been assessed for cosmetic use at specific concentrations. But they’re not natural, they won’t appear on an ingredients list by their true chemical names, and they don’t offer the complexity of a genuine botanical material.
Essential oils are different: extracted directly from plant material by steam distillation or cold pressing, they’re natural and traceable. Absolutes are extracted via solvent, capturing a wider range of aromatic compounds than distillation allows. Both are natural. Neither is a fragrance oil.
Frequently Asked Questions {#faq}
What is the difference between scent and fragrance?
Scent refers to any natural smell — the inherent odour of a material, place, or living thing. Fragrance refers either to a pleasant smell in general use, or specifically to a synthetic aroma compound used in cosmetics. When “fragrance” appears on an ingredients list, it almost always means synthetic chemicals.
What is the difference between scent and perfume?
Scent is the smell itself — raw and natural. Perfume is a composed, intentional product designed to be worn on the body. A perfume contains scents (natural materials) or fragrances (synthetic compounds), or both, combined in a specific formulation.
What is the difference between fragrance and perfume?
Fragrance is an ingredient — a formulated aroma compound, usually synthetic. Perfume is a finished product: a scented liquid worn on the body. A perfume is made from fragrances and/or natural scent materials. On EU labels, synthetic fragrance compounds appear under the ingredient name “parfum” — the French word for perfume — which adds to the confusion.
What does fragrance mean on an ingredients list?
On a cosmetics ingredients list, “fragrance” or “parfum” is a legal catch-all covering any aroma compound — including synthetic musks, phthalates, Iso E Super, and other compounds that manufacturers aren’t required to name individually. It’s one of the least transparent ingredient declarations in cosmetics regulation.
What is a natural fragrance?
Natural fragrance refers to a scented formulation made exclusively from botanical materials: essential oils, absolutes, resins, and other plant-derived compounds. Unlike synthetic fragrance, natural fragrance ingredients can be listed individually by name because they’re traceable materials with regulated identities.
All Prosody London natural perfumes are formulated this way — every ingredient named, nothing hidden. Because natural materials interact so distinctively with skin chemistry, they also layer particularly well — our scent stacking guide explains how to build a personalised combination. The best way to understand the difference is to smell it — our natural perfume sample set lets you do exactly that.
Can you smell the difference between natural scent and synthetic fragrance?
Yes, usually — though it takes some experience. Natural materials are more complex, evolve over time on skin, and tend to smell rounder and less linear. Synthetic materials are brighter, more consistent, and more persistent. The difference is most obvious in materials like oud, jasmine, rose, and vetiver — where the natural version is dramatically more complex than its synthetic counterpart.
Is scent the same as smell?
Broadly yes — scent and smell both refer to the olfactory perception of volatile compounds. Smell is the more neutral, physiological term. Scent carries a slight connotation of pleasantness and is more often used in the context of natural materials and perfumery. In everyday use the words are interchangeable.
What is the difference between smell and fragrance?
Smell is the physiological act of olfactory perception — what the nose does. Fragrance is either a pleasant smell, or a synthetic aroma compound in an ingredients list. You smell a fragrance; the fragrance itself is the thing being smelled.
