How Fragrance Actually Works on Skin
A perfume is not a single scent. It is a structured composition of multiple ingredients designed to evolve over time after application. The standard structure uses three layers called notes.
Top notes: The first thing you smell after spraying. Light, volatile molecules that evaporate fastest. Examples: citrus (bergamot, lemon, grapefruit), green notes, herbs, light aldehydes. Duration: 15 to 30 minutes.
Heart notes (middle notes): The scent that emerges after the top notes fade. These form the core of the fragrance character. Examples: florals (rose, jasmine, ylang-ylang), spices (cardamom, cinnamon), fruity notes. Duration: 30 minutes to 3 hours.
Base notes: The deepest layer that lingers longest and forms the foundation on the skin. Examples: woods (sandalwood, cedarwood), musks, amber, vanilla, resins, labdanum. Duration: 3 to 24 hours.
Why testing briefly fails you: When you smell a fragrance on a blotter or on your skin for 30 seconds in a shop, you are smelling only the top notes. The fragrance you will actually wear all day is the heart and base combination, which you have not yet experienced.
The Six Main Fragrance Families
Floral
The largest fragrance category globally. Built primarily on flower essences and synthetics that replicate flower scents.
Subtypes:
- Single floral (soliflore): One dominant flower (rose, jasmine, tuberose)
- Floral bouquet: Multiple flowers combined
- Soft floral: Floral notes softened with musk, powder or aldehydes
Who it suits: Widely appreciated; the most universally wearable family. Ranges from fresh (green floral, light rose) to intensely rich (tuberose, jasmine soliflore).
Oriental (Amber)
Rich, warm and long-lasting. Built on amber, resins, vanilla, balsams and spices.
Subtypes:
- Soft oriental: Lighter amber; floral or citrus elements
- Oriental: Classic combination of amber, spice and resin
- Woody oriental: More earthy and woody base
Who it suits: Better longevity on dry or warm skin. Works well in cooler weather.
Woody
Built on dry woods, mosses and earthy base notes. Includes the fougère (fern) family, chypre (oakmoss, bergamot, labdanum) and vetiver-based scents.
Who it suits: Popular in unisex and masculine fragrances; equally wearable by anyone. Long longevity on warm skin.
Fresh
Citrus, aquatic, green and ozonic notes. Light, clean, low longevity.
Subtypes:
- Citrus: Bergamot, lemon, neroli
- Aquatic: Marine, ozonic notes
- Green: Cut grass, herbs, leaves
Who it suits: Ideal for hot weather, office environments and people who prefer subtle fragrance. Reapplication required; base notes are minimal.

The same fragrance smells different on different people. This is not marketing; it is chemistry.
Skin pH: Skin with a lower pH (slightly more acidic) amplifies certain notes, particularly musks and orientals. Higher pH skin (common in dry skin) produces less projection of top and heart notes.
Body heat: Warm skin generates more evaporation, which intensifies and amplifies fragrance. Cold skin produces lower sillage (the scent trail you leave behind).
Skin moisture: Hydrated skin holds fragrance significantly longer than dry skin. Applying fragrance-free moisturiser before spraying adds hours to the longevity of most fragrances.
Sebum production: Oily skin amplifies and retains base notes (musks, woods) more effectively than dry skin. People with oily skin often find oriental and woody fragrances last longer and project more strongly on them.
The Correct Way to Test Fragrance
- Apply to skin, not a blotter. The paper blotter shows you the composition but not how it interacts with your chemistry.
- Apply to pulse points (inner wrist, inner elbow, base of throat). These areas generate heat that activates evaporation.
- Wait 30 minutes minimum before evaluating the heart notes. One hour is more accurate.
- Smell with a neutral nose. Coffee beans are not required; breathing fresh air between tests resets the olfactory receptors equally well.
- Evaluate after 4 to 6 hours for the base note longevity. This is the scent you will be wearing at the end of the day.
Testing limit: Most people's olfactory receptors saturate after 3 to 4 fragrances in a session. Testing more than this produces inaccurate judgements. Request samples of the candidates and test each on different days.
Fragrance Concentration and What Each Level Means
| Concentration | Name | Fragrance Oil % | Longevity |
|---|---|---|---|
| Highest | Extrait de Parfum | 20% to 40% | 6 to 12 hours |
| High | Eau de Parfum (EDP) | 15% to 20% | 4 to 8 hours |
| Medium | Eau de Toilette (EDT) | 5% to 15% | 2 to 4 hours |
| Light | Eau de Cologne (EDC) | 2% to 5% | 1 to 2 hours |
| Lowest | Eau Fraiche | 1% to 3% | 1 hour or less |
Higher concentration does not always mean better. Some fragrances are formulated specifically for EDT strength; the higher EDP concentration of the same fragrance changes the balance of notes. Always try both concentrations if available before assuming the higher one is superior.
