Eau de parfum (EDP), eau de toilette (EDT), and cologne are not different fragrances, they're different concentrations of perfume oil dissolved in alcohol. The more oil, the stronger and longer-lasting the scent, and usually the higher the price. The same fragrance can be sold in several concentrations, and they can smell noticeably different from one another. Once you understand the labels, you stop overpaying for strength you don't need, and stop being disappointed when a "splash" fades by lunch.
The quick answer
| Label | Typical oil concentration | Roughly how long it lasts | Best for |
|---|---|---|---|
| Parfum / Extrait | 20 to 30% | 6 to 12+ hours | Maximum strength & longevity; a little goes far |
| Eau de Parfum (EDP) | 15 to 20% | 5 to 8 hours | The everyday sweet spot, strong but wearable |
| Eau de Toilette (EDT) | 5 to 15% | 3 to 5 hours | Daytime, warm weather, the office |
| Eau de Cologne (EDC) | 2 to 5% | 2 to 3 hours | Light, refreshing, frequent re-application |
| Eau Fraîche | 1 to 3% | 1 to 2 hours | The lightest splash, hot days |
These ranges are industry conventions, not legal definitions, brands vary. But the order always holds: parfum is strongest, eau fraîche is lightest.
What changes when the concentration changes?
Three things move together as oil content rises:
- Strength (projection): higher concentrations push more scent into the air around you.
- Longevity: more oil means the fragrance survives longer on skin before fading.
- Character: this is the surprise. Higher concentrations often emphasize the deeper base notes, woods, amber, musk, so an EDP can smell richer and "darker" than the EDT of the very same fragrance, which leans brighter and fresher up top.
That last point is why seasoned wearers sometimes own both the EDT and the EDP of a scent they love: the EDT for summer days, the EDP for cold nights.
Is "cologne" a concentration or a category?
Both, which is where the confusion starts. Strictly, eau de cologne is a light 2 to 5% concentration. But in everyday North American usage, "cologne" is also shorthand for "men's fragrance" of any strength. So a bottle marketed as a men's "cologne" might actually be an eau de toilette or even an eau de parfum, always check the label on the bottle for the real concentration. On our product pages the concentration is listed in the title and details so you're never guessing.
Which concentration should you buy?
Match it to where and when you'll wear the scent:
- For the office or hot weather: an EDT or cologne. Lighter, fresher, less likely to overwhelm a meeting room.
- For everyday all-rounder use: an EDP. It's the modern default for a reason, strong enough to last a workday, not so heavy it announces you from the elevator.
- For evenings, winter, or special occasions: EDP or parfum. You want richness and staying power.
- If you love to re-apply and enjoy a scent that stays close to the skin, a lighter concentration is a feature, not a flaw.
Does a higher concentration mean better value?
Not automatically. Parfum costs more per millilitre, but you also use far less, one or two dabs versus several sprays, so a small bottle lasts a long time. An EDT is cheaper up front but you may spray more and re-apply during the day. The honest way to compare value is cost per wearing, not cost per bottle. And the only way to know how much you actually need is to wear it: some skins hold fragrance for hours, others drink it up. Sampling a scent before committing to any concentration saves the most money of all.
How to decide without overspending
If you're torn between concentrations of a fragrance you like, sample the EDP, the richest version most people end up wearing, and see how it lasts on your skin over a full day. If it's still going strong at hour six, you may be happy stepping down to the EDT for daily use. If it fades by lunch, you'll want the EDP or parfum. You can try both versions cheaply with a Build Your Own Kit of decants before paying full-bottle prices. New to testing on skin?

Frequently asked questions
Is eau de parfum stronger than eau de toilette?
Yes. Eau de parfum contains more perfume oil (about 15 to 20%) than eau de toilette (about 5 to 15%), so it generally projects more and lasts longer, typically 5 to 8 hours versus 3 to 5.
Why does the same perfume smell different as an EDP and an EDT?
Higher concentrations emphasize the heavier base notes, so an EDP often smells richer and deeper, while the EDT version leans brighter and fresher in its opening. The brands sometimes also tweak the formula between concentrations.
Does eau de parfum last longer than cologne?
Almost always. Eau de cologne is one of the lightest concentrations (2 to 5% oil) and usually lasts 2 to 3 hours, while an eau de parfum can last 5 to 8 hours or more.
What's the strongest type of fragrance?
Parfum (also called extrait de parfum), at roughly 20 to 30% perfume oil. It lasts the longest and projects the most, so you only need a small amount.
Which concentration is best for beginners?
An eau de toilette or eau de parfum. They're the most versatile and the most widely available, and they're forgiving if you over-apply while you're still learning how much you need.
Bottom line
The letters on the bottle are just a strength dial: parfum at the top, eau fraîche at the bottom, EDP and EDT in the everyday middle. Pick the strength that fits the weather and the occasion, check the actual concentration on the label rather than trusting the word "cologne," and sample before you buy a full bottle of any of them. Browse by what suits you in all fragrances, or let the Scent Finder narrow it down.
