Perfume

How a Fragrance Changes Over the First Hour

A perfume is built in three stages that arrive in order of weight. Top notes are the lightest and most volatile, usually citrus or green, and they are gone within fifteen minutes. The heart follows and carries the character, often floral or spiced. The base is what remains after an hour, built from woods, amber, musk and resins. Judge a fragrance on how it smells after an hour on your own skin, because the opening you smell in the shop is the part you will wear the least. Paper strips skip the skin entirely and only ever show you the top.

What the Concentration on the Label Means

The names on a bottle describe how much perfume oil sits in the alcohol, and that single number drives both cost and wear time. Eau de cologne is the lightest, eau de toilette sits in the middle, and eau de parfum carries the highest concentration of the three. A higher concentration is not a stronger smell so much as a longer one, projecting less loudly but staying closer to the skin for hours more. This is why an eau de parfum often needs fewer sprays than the eau de toilette version of the same scent rather than more.

Making a Scent Last Without Applying More

Fragrance holds to oil and evaporates off dryness, which is the whole trick. An unscented body oil or butter applied first will hold a perfume on the skin far longer than adding extra sprays will. Pulse points work because they are warm, and warmth releases the scent gradually rather than all at once. Two habits shorten a bottle's life instead: rubbing the wrists together, which crushes the top notes, and storing the bottle on a sunny shelf, where light and heat break down the composition well before the liquid runs out.

For the lighter alternative worn closer to the skin, the body mists sit in Mists & Sprays, and the unscented oils and butters that make a fragrance last are grouped in Body Oil.
