What longevity means
In fragrance, longevity describes how long a fragrance remains detectable on skin after application. A fragrance with excellent longevity can last 10–12 hours or more; a fragrance with poor longevity may fade completely within 1–2 hours. Longevity is one of the most commonly discussed fragrance properties, and one of the most personal — the same fragrance can perform very differently on different people.
What determines longevity
- Concentration: Parfum and EdP generally outlast EdT and EdC, which outlast body sprays and light mists.
- Molecular weight of ingredients: Heavy, dense aromatic molecules (musks, resins, oud, woods) evaporate slowly and anchor a fragrance on skin. Light, volatile molecules (citrus, light herbs) evaporate quickly.
- Skin type: Oilier skin holds fragrance longer than dry skin. Skin pH also affects how aromatic molecules bond to the skin surface.
- Application method: Moisturised skin holds fragrance longer. Applying to pulse points (warm areas) extends longevity by promoting gradual evaporation.
- Temperature and humidity: Warm, humid conditions increase projection but can also accelerate evaporation. Cold conditions slow evaporation, potentially extending longevity.
Improving longevity
The most effective single change most people can make: apply an unscented moisturiser to skin before spraying fragrance. The oils in the moisturiser give fragrance molecules something to bind to, often extending longevity by several hours. This is more effective than simply applying more of the fragrance.
