Two fragrances can share a name and smell almost the same, yet one lasts all day and the other fades by lunch. The difference is usually a few letters on the label: the concentration.
What concentration means
Every fragrance is a blend of aromatic oils diluted in alcohol, and sometimes a little water. The concentration is the share of that blend that is perfume oil. More oil generally means a scent that lasts longer and sits more densely on skin; more alcohol means a lighter, brighter spray that fades sooner.
The common labels
There is no single legal standard and houses vary, but these are the usual ranges:
- Parfum or extrait de parfum: roughly 20–30% oil, sometimes more. The richest and longest-lasting, and usually the most expensive.
- Eau de parfum (EDP): roughly 15–20%. The most popular balance of strength and price.
- Eau de toilette (EDT): roughly 5–15%. Lighter and fresher, with a shorter life on skin.
- Eau de cologne (EDC): roughly 2–5%. A quick, refreshing splash.
Longevity vs projection
These two often get confused. Longevity is how long a fragrance stays detectable on you. Projection, or sillage, is how far it reaches from your skin. Higher oil concentration mainly improves longevity. Projection depends just as much on the materials themselves: some fresh, airy molecules project widely even at low concentration, while dense oud or amber can sit close to the skin for hours.
Why concentration matters more in hot climates
Heat speeds up evaporation. A light EDT that lasts five or six hours in a cool European autumn can be gone in two in a Pakistani summer. That is a big part of why people here find some designer fragrances disappointing for the price: their concentration was chosen for a different climate.
Where our fragrances sit
We build our Signature range at up to 40% oil — above the typical EDP range — using imported oils macerated in our Karachi lab. That extra oil is the budget going into the bottle rather than into packaging and advertising. Bottles like Bella Rossa and Titanic are made this way; see them all in the Signature collection.
Does higher always mean better?
Not automatically. A high concentration of a poorly balanced blend is still a poorly balanced blend, and a very rich scent can be too much for a hot office. What matters is choosing the right strength for how you wear fragrance:
- Long days, weddings and evenings: a high-concentration EDP or parfum.
- Office and daytime: an EDP applied lightly, or a fresher EDT.
- Gym and quick refreshes: a cologne or light EDT.
Getting the most from any concentration
Apply to moisturised skin, don't rub your wrists, and spray fabric as well as skin. There's more in our guide to making perfume last longer.
