Lesson 1 of 2 in this stage
Projection and sillage: who will notice the scent?
Distinguish reach from a moving scent trail and choose an amount suited to the setting.
Three words answer three questions
| Term | Question |
|---|---|
| Longevity | How long does it remain detectable? |
| Projection | How far does it reach at this moment? |
| Sillage | What trail does it leave as you move? |
Close to skin is not a defect
In a small office or transport, a quiet personal scent may be preferable. Outdoors, you might prefer more presence. There is no ideal projection for everyone; suitability depends on scent, setting and comfort. People differ in fragrance sensitivity, so shared-space consideration belongs in good use.
Airflow and movement affect what others receive
Volatile materials travel through air to the nose. Air currents, movement and temperature can change their distribution; wrist-to-nose smelling alone does not assess projection. If asking someone else, obtain their agreement and use an ordinary distance rather than an unexpected spray or close-to-face test.
Projection, longevity and trail are different measures
Projection means how noticeable a perfume is away from the application point. Longevity is how long it remains perceptible. Sillage is the scent trail that may follow someone in motion. A fragrance can last close to the skin yet have modest projection, so “can I still smell it?” cannot answer all three questions.
Test socially, not aggressively
Start with a moderate application in a ventilated setting and ask another person for an impression at a sensible distance after an agreed interval instead of overwhelming a room with sprays. People vary in fragrance sensitivity. In offices, vehicles and crowded indoor spaces, other people's comfort is part of choosing an appropriate perfume, not a secondary concern.
Your turn
Use what you learned
A perfume is noticed after its wearer passes but is quiet while seated. Which term describes the passing trail?
See the answer and why
Sillage describes the trail. Reach from a stationary wearer concerns projection; persistence over time concerns longevity.
Check your understanding
Answer four questions, then review the reason for each answer. You can retry.
Measure presence without guessing
With a consistent application, ask another person to rate detectability from the same agreed distance in a ventilated space, without knowing which scent you chose. Repeat at 15 and 60 minutes.
Air changes the result
Air movement, body warmth and room size affect odor transport. One anecdote cannot establish universal projection.
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.
