Perfume Terminology
Sillage
The scent trail you leave behind.
How far the perfume projects into the air after you walk past. Strong sillage means people notice you from a distance. Soft sillage stays close to the skin.
Projection
How far the scent radiates from skin.
The initial scent cloud around you in the first 30-90 minutes. High projection fills a room. Low projection is intimate (skin scent).
Longevity
How long the perfume lasts.
From a few hours (EDT) to 10+ hours (extrait). Depends on concentration, skin chemistry, climate and application method.
Concentration
Percentage of pure fragrance oil.
Higher concentration usually means stronger and longer lasting. See the full comparison table below.
Notes
Individual scent ingredients.
Top notes (first impression), heart notes (core character), base notes (dry-down and longevity). Together they form the fragrance pyramid.
Accords
Blended groups of notes.
A harmonious combination that creates a new impression (for example a fougere or oriental accord). Many modern perfumes are described by their main accords.
The Fragrance Pyramid
Top Notes
First 5-15 min - Citrus, herbs, light fruits
Heart / Middle Notes
30 min - 3-4 hrs - Florals, spices, fruits
Base Notes
Lasts hours to all day - Woods, resins, musks, vanilla
A well-built perfume evolves over time. What you smell at first spray is rarely the final character.
Concentration Types
1-3%Eau Fraiche
2-5%Cologne
5-15%EDT
15-20%EDP
20-40%Parfum
| Type | Oil % | Typical Longevity | Best For |
|---|---|---|---|
| Eau Fraiche | 1-3% | 1-2 hours | Very light, summer, after-sport |
| Eau de Cologne | 2-5% | 2-3 hours | Fresh, classic, daytime |
| Eau de Toilette (EDT) | 5-15% | 3-5 hours | Daily wear, office, warmer weather |
| Eau de Parfum (EDP) | 15-20% | 6-8+ hours | Most popular perfume strength |
| Parfum / Extrait | 20-40% | 8-12+ hours | Evening, special occasions, cold weather |

Testing and Perception
1
Never judge on paper alone
Paper shows only top notes. Skin chemistry changes everything.
2
Spray on clean, moisturized skin
Use unscented moisturizer first for better development.
3
Wait 30-60 minutes
Heart and base notes appear. The real perfume is the dry-down.
4
Test max 2-3 at a time
Nose fatigue is real. Give your nose time between sprays.
5
Live with it for a few days
A scent can feel different in the morning, after exercise or in heat.
Pro tip: Your own nose adapts quickly. Ask someone else how strong it is after an hour.
Sillage - The Scent Trail
How to roughly judge sillage
- Spray once on the inner wrist. Wait 10-15 minutes.
- Ask someone to walk past at normal speed from 1-2 meters.
- If they clearly smell it - moderate to strong sillage.
- If only when very close - soft / skin scent.
- Repeat after 1 hour and after 3-4 hours.
Notes that increase sillage
- Ambroxan, Iso E Super, Hedione, strong musks
- Spices (pepper, cinnamon), incense, oud
- Heavy florals (tuberose, jasmine sambac)
- Higher concentration (EDP / Parfum) usually projects more
Projection - How Far It Radiates
Simple way to assess projection
- Spray 1-2 times on chest or neck.
- After 15-20 minutes, ask someone to approach from 2-3 meters.
- Note the distance at which they first detect the scent.
- Strong = arm length or more. Soft = within 30-50 cm.
Materials known for good projection
- Iso E Super, Ambroxan, Calone, strong citrus
- Aldehydes (classic bright effect)
- Pepper, ginger, incense
Longevity - On Skin and Clothes
Typical longevity (visual)
How to measure longevity
- Spray once on clean skin at a known time.
- Check every hour (do not rub).
- Also test on fabric - often lasts 1-3 days.
Notes famous for longevity
- Vanilla, tonka, amber, musk, sandalwood, patchouli, oud, resins
- Ambroxan, Iso E Super, synthetic musks, vanillin
Pro tip: Moisturized skin + light unscented lotion underneath dramatically improves longevity.

How to identify: Smell the dry-down after 1-2 hours. The dominant character is usually the main accord family.
What to Read on the Bottle
- Concentration - EDT, EDP, Parfum, Cologne. Higher usually lasts longer.
- Version name - Intense, Elixir, Sport are often different formulas.
- Batch code - small numbers/letters on the bottom for age and authenticity.
- Volume - 30 / 50 / 100 ml. Smaller is better for testing.
- Ingredients list - useful if you have allergies.
Watch for fakes: cheap plastic, misspellings, missing batch code, inconsistent branding.
Layering and Complementary Products
Layering techniques
- Unscented moisturizer first, then perfume (best longevity boost).
- Matching body lotion or shower gel from the same line.
- Light body mist underneath a stronger EDP.
- Two complementary perfumes (fresh citrus + soft musk).
- Stronger scent on clothes, lighter on skin.
Body Mist / Body Spray
Very light fragrance.
Low concentration, short longevity. Great for hot weather or layering under perfume. Spray freely on body and clothes.
Deodorant
Controls odor bacteria.
Look for fragrance-free or matching-scent versions. Apply to clean dry underarms. Does not stop sweat.
Antiperspirant
Reduces sweat itself.
Contains aluminum salts. Best applied at night on dry skin. Can slightly affect how perfume sits if heavily applied.
Body Lotion / Oil
Best longevity booster.
Apply unscented or matching lotion, wait a minute, then spray perfume. Oil-based products hold scent especially well.
Perfume Application
Best pulse points
- Sides of the neck / base of throat
- Inner wrists (do not rub)
- Behind the ears
- Inner elbows
- Behind the knees
For Men
Practical application.
- Neck sides and chest (1-2 sprays)
- Inner wrists
- One spray on back of neck or shirt
- 2-4 sprays total is usually enough
For Women
Classic and flexible.
- Neck, wrists, decolletage
- Hair (very lightly) or scarf for trail
- Behind knees for elegant movement
- Same rule: less is more with strong EDPs
Never rub your wrists together - it crushes top notes and can make the scent turn sharper.
Men vs Women Perfumes
- Marketed to men: woods, aromatics, spices, leather, fresh/aquatic, fougere.
- Marketed to women: florals, gourmands, fruity notes, soft musks, powdery accords.
- Modern reality: most fragrances are wearable by anyone. Unisex is very common.
- Ignore the gender label if you love the smell - wear what suits you.
Expert Pro Tips
Storage
Keep cool and dark.
Heat, light and air degrade fragrance. Store upright in a cupboard, never in the bathroom or on a sunny windowsill.
Skin prep
Moisturize first.
Perfume lasts significantly longer on hydrated skin. Use an unscented lotion or matching product.
Distance
Spray from 15-20 cm.
Too close creates a wet patch. Too far wastes product.
Clothes
Fabric holds scent longer.
A light spray on scarf, jacket lining or shirt can create beautiful sillage for hours or days. Test for staining first.
Rotation
Do not wear the same every day.
Your nose goes blind to it. Rotating 3-5 fragrances keeps each one smelling special.
Test first
Small size before full bottle.
Buy 5-10 ml decants or travel sprays. Live with a scent for a week before committing.
