Why do some perfumes last 10 hours and others 2?

Our overview of how long FAAN perfumes last covers the ratings. This article goes one level deeper, into the mechanics, so you can predict from a notes list what will last.

Molecules and evaporation

A perfume is a mix of dozens of materials in alcohol. Once sprayed, the alcohol leaves in seconds and each material starts to evaporate at its own pace. Small, light molecules go first. Large, heavy ones stay. That is why a perfume changes over time: you are smelling the order in which materials leave.

Perfumers call the result a pyramid. The top notes are the quick ones, the heart is the middle, and the base is the slow end. The base is what remains on skin at hour six.

Base notes as anchors

Materials like resins, balsams, woods, amber and many musks are slow. They also hold on to lighter materials and slow them down. In perfumery this is the job of a fixative. A base built from these gives the whole scent a longer life.

You can see the effect in our ratings. Amjad Honour has vanilla, amber, oud, ambergris and benzoin in the base, and is rated 5 out of 5 for longevity. Amjad Kingdom has labdanum, ambergris, musk and Amber Xtreme, also 5 out of 5. Amjad Coral has pear, bergamot and mandarin on top and musk, cedar and light woods below, and is rated 3 out of 5.

Concentration, again

More fragrance oil means more material to evaporate, which usually means longer wear. An Extrait de Parfum holds more oil than an Eau de Parfum, as covered in what an Extrait de Parfum is. But concentration is only part of the answer. A light blend at high concentration still fades fast. A heavy blend at lower concentration can outlast it.

Skin, humidity and clothes

Skin that is warm and dry pushes scent out and lets it go quickly. Cool, moist skin holds it. Moisturising first gives the perfume something to cling to. Humid air can slow evaporation, and hot, dry air speeds it up. Clothes are the easy fix: fabric does not warm or dry out, so it releases scent slowly. A shirt can hold a base note for a day or more.

Why you stop smelling it

There is a second reason a perfume seems to fade, and it has nothing to do with the bottle. The nose adapts. After a few minutes of the same smell, receptors turn down the signal. This is normal, and it is why a perfume you love can seem to vanish within the hour while a colleague still catches it. Test it by smelling your sleeve after a short walk outdoors, or ask someone you trust.

What to look for on a notes list

• Longer lasting: resins (benzoin, labdanum), amber, vanilla, oud, sandalwood, ambergris, heavy musks.
• Shorter lasting: citrus (bergamot, lemon, mandarin), light fruit, many light florals.
• A good sign: at least three or four heavy materials in the base.

These are tendencies, not laws, and the blend matters as much as any one ingredient. Check the rating on the product page too. See all FAAN perfumes for the ratings of every bottle.

FAQ

Do expensive perfumes last longer?

Not necessarily. Price does not set the wear time. The blend and the concentration do.

Can I make a short-lived perfume last longer?

Partly. Moisturise first, spray clothes as well as skin and store the bottle away from heat.

Is a bigger bottle longer lasting on skin?

No. Size changes how much you have, not how it wears.
