What Actually Makes a Fragrance Last
Concentration matters. What the fragrance is made of matters just as much
"Does it last?" is the question asked about almost every fragrance. The usual answer is to buy the stronger concentration. That helps, but wearers' own votes show it's only half the story.
Each fragrance in our catalog carries longevity votes in five steps: very weak, weak, moderate, long lasting and eternal. We turn those into a single score from 0 (everyone says very weak) to 10 (everyone says eternal). A score around 5 means most people call it moderate; around 7.5, long lasting. For everything below we used fragrances with at least 200 ratings.
Concentration: real, but smaller than you'd think
Average longevity scores by concentration:
Eau de cologne and cologne sit around 5.0. Eau de toilette averages 5.1. Eau de parfum averages 5.75. Parfum averages 6.3, and extrait 7.1.
So the order is what you'd expect, and the gap between an EDT and an extrait is real: about two points, or the difference between "moderate" and "long lasting".
The gap between an oud and an aquatic is as wide as the gap between an extrait and an eau de toilette.
The cleanest test is the same fragrance in two strengths. We found 93 lines with both an EDT and an EDP. In 84 of them, nine in ten, wearers voted the EDP longer lasting. The average gain was 0.6 points. Some gaps are bigger: Armani Code goes from 4.9 as an EDT to 6.3 as an EDP, and Shalimar from 6.1 to 7.0.
The ingredients matter as much
Now group the same fragrances by their leading accords instead. Fragrances led by oud average 7.2. Leather averages 6.7, patchouli and amber 6.5, warm spice 6.4. At the other end, citrus averages 5.3, green 5.25, and fresh and aquatic fragrances 5.0. It's why perfumes that smell like the beach rarely last as long as those that smell like leather.
The gap between an oud and an aquatic is as wide as the gap between an extrait and an eau de toilette.
That's chemistry, not marketing. Base materials like resins, woods, musks and oud are heavy molecules that evaporate slowly. Citrus oils and the bright, airy materials in aquatic fragrances are light and leave fast. A citrus fragrance at a high concentration is still mostly citrus, and citrus is short-lived.
What this means when you buy
If longevity is your priority, look at the accords before the concentration. A woody amber EDT will often outlast a citrus EDP.
If you love a fresh fragrance and want more time from it, the EDP or "intense" version usually helps, by roughly half a point on average. Or layer it over something with a deeper base that shares a note; see ten layering pairs for how.
Every fragrance page shows its own longevity and sillage votes, so you don't have to rely on the averages.
And what you can do on skin
A few things genuinely help, and none cost anything. Moisturised skin holds fragrance longer than dry skin, so apply after a shower over an unscented lotion. Spray, don't rub: rubbing warms the skin and speeds up the top notes. Fabric holds scent longer than skin, so one spray on a scarf or jacket goes a long way, as long as the fabric won't stain.
And remember you stop smelling your own fragrance long before other people do. If you can't smell it after an hour, that's often your nose adapting, not the fragrance fading.
A note on method: older records store longevity as relative bar heights and newer ones as raw vote counts. We convert both to shares of each fragrance's own votes before scoring, so every fragrance counts once.
