Longevity
Longevity means how long perfume stays detectable. Learn how to assess wear on skin, read community ratings, and separate lasting power from projection.

Longevity is how long a fragrance remains detectable after you apply it. In a perfume review, it usually refers to wear on skin. A scent that remains on a scarf overnight has demonstrated fabric persistence, which is a different result.
The endpoint matters. “Lasted until dinner” might mean noticeable to someone beside you, or only detectable with your nose close to your wrist. Both observations can be useful if the reviewer explains what they mean. Neither describes the size of the scent trail throughout the day.
Concentration labels and note lists cannot supply the missing hours. For a useful comparison, try the exact version under similar conditions, record your application and check it at intervals. If you lose track of the scent, another person’s observation can help; your own perception may have adapted.
- Longevity
- How long a fragrance remains detectable after application. State whether you mean skin, clothing or a paper strip; these are different tests.
- Projection
- How far from the wearer a fragrance can be detected at a particular time. Air movement and the observer affect the result.
- Sillage
- The scent trail left as the wearer moves through a space. It describes a passing trail rather than a fixed distance around the body.
- Longevity rating
- A community opinion on a rating scale. A score of 8 out of 10 does not mean eight hours of wear.
- Olfactory adaptation
- Reduced perception after continued or repeated exposure to a smell. It can make a fragrance seem quieter to its wearer without establishing whether it has faded for everyone.
