Lesson 2 of 2 in this stage
Longevity: how long does the scent remain detectable?
Distinguish lasting presence from intensity and test beyond the first spray.
Longevity is duration, not loudness
Longevity is how long a scent remains detectable under particular conditions. One perfume can start strongly and settle quickly; another can remain quietly close to skin for longer. 'It is not filling the room' does not mean it has vanished. Distinguish close-range detectability from reach to other people.
EDT and EDP do not promise fixed hours
These are common concentration or product-style terms, but ranges and formulations vary, and two versions may have different compositions. Not every EDP outlasts every EDT. Materials, atomizers, application site and conditions matter. Your own perception can also change with adaptation while another person still notices the scent.
A simple test instead of a universal hour claim
Try one product and record application time, site and sprays. Revisit at intervals rather than sniff continuously. Use descriptions such as 'clear nearby', 'faint' or 'no longer noticed'. Compare another perfume under similar conditions. Do not automatically add sprays when you stop noticing it; take a fresh-air break and reassess.
Longevity is not one universal number
Longevity describes how long a scent remains perceptible, but the blend, amount applied, surface, environment and olfactory adaptation all affect the experience. No longer noticing your own fragrance does not prove everyone else has stopped detecting it. Judge repeated observations instead of making a verdict from the first half-hour.
Run a fair comparison
- Compare two finished fragrances under similar conditions and approximately similar application amounts on separate blotters.
- Record perceived strength and character at several intervals instead of writing only “lasting” or “weak.”
- Distinguish close-to-skin persistence from what other people can perceive at a distance.
Price, sweetness and number of sprays do not by themselves determine how long a formulation will last.
Your turn
Use what you learned
What details should accompany 'It lasted five hours'?
See the answer and why
Skin or paper, sprays, conditions and the endpoint: no longer detected nearby or no longer reaching others? These make the claim interpretable.
Check your understanding
Answer four questions, then review the reason for each answer. You can retry.
A fair longevity test
Use equal sprays from two perfumes on equivalent strips, record the time, and rate detectability after 15 minutes, 1, 3 and 6 hours. Avoid constant sniffing because olfactory adaptation can make a persistent odor seem weaker.
Longevity is not projection
A scent may remain detectable close to the skin without travelling far. Longevity is persistence; projection is distance and presence.
Apply it to SESH: explore the fragrance collection, compare each perfume’s note description, then test the scent rather than relying on copy alone.
SESH case study: Love by Sheeka describes peach and freesia in its opening, rose and jasmine in its heart, and vanilla, patchouli and vetiver in its base. Compare this note map with your own observations.
