Perfume longevity vs. sillage and how to choose the perfect perfume

When searching for a new fragrance, perfume enthusiasts discuss two main terms: “Longevity” and ”Sillage & Projection”. Despite their close connection to the fragrance composition, they express two completely different concepts in the world of perfumery.

What is fragrance longevity? (Longevity)

Fragrance longevity refers to the duration for which the fragrance remains perceptible on the skin or clothes from the moment it is sprayed until it completely disappears.

• Factors affecting longevity:

  • Concentration of essential oils: Fragrances with a concentration of Perfume or Eau de Parfum contain a higher percentage of oils compared to Eau de Toilette.

  • Base notes: Fragrances containing oud, amber, musk, and woods have higher longevity due to the heaviness of their molecules and their delayed evaporation.

What is fragrance projection? (Projection / Sillage)

Projection expresses the extent to which the fragrance spreads in the air around you, and the distance from which others can smell your scent without needing to get very close to you.

• Factors affecting projection:

  • Top notes: Citrus and light floral components evaporate quickly to spread strongly in the air.

  • Body temperature and weather: Heat increases the rate of fragrance evaporation, which increases projection in summer or during movement.

How to choose between them based on the occasion?

• For work and meetings: It is preferable to choose fragrances with high longevity and medium to quiet projection so that the components are not annoying to those around you in enclosed spaces.

• For events and parties: Fragrances with strong projection and high longevity are the ideal choice to make a distinctive impression that reflects your presence.
