What the concentrations mean
Fragrances are graded by how much aromatic oil they contain, diluted in alcohol. From lightest to strongest: Eau Fraîche (1–3%), Eau de Cologne (2–5%), Eau de Toilette (5–15%), Eau de Parfum (15–20%), and Parfum / Extrait (20–40%). More oil means more intensity, more longevity, and usually a higher price.
How long each lasts
On skin, an EDT typically lasts 4–6 hours, an EDP 6–8+ hours, and an Extrait 8–24 hours. These are averages — oily skin holds fragrance longer than dry skin, and heavy base notes (oud, amber, woods) outlast light citrus tops. Use our Longevity Calculator for a personalised estimate.
Do they smell different?
Often, yes. The same fragrance in EDT and EDP is usually reformulated, not just diluted — the EDP may emphasise the warm base notes while the EDT leans fresher and brighter at the top. Dior Sauvage EDT and EDP, for example, are noticeably different in character, not just strength.
Which should you buy?
Choose EDT for hot weather, daytime and office wear where you want something fresh and unobtrusive. Choose EDP for evenings, cooler weather and occasions where you want projection and longevity. If a fragrance is offered in both, sample each — you may prefer the EDT's lighter take.
