Fragrance FAQ: 15 Most Common Perfume Questions Answered
Everything you need to know about fragrances, from concentration types to storage tips, answered by experts.
Whether you're new to fragrances or a seasoned collector, these are the questions we hear most often. We've compiled clear, practical answers to help you make better fragrance decisions.
The Basics
What is the difference between EDT and EDP?
Eau de Toilette (EDT) has 5-15% fragrance concentration and typically lasts 3-5 hours. Eau de Parfum (EDP) has 15-20% concentration and lasts 6-8 hours. EDP is stronger, more intense, and generally more expensive. For daily office wear, EDT is often preferred; for evenings or special occasions, EDP provides better presence.
What is Extrait de Parfum?
Extrait de Parfum (or pure perfume) has the highest concentration at 20-40%. It lasts 8-12+ hours and requires fewer sprays — typically just 2-3. It's the most expensive concentration but offers the richest, most nuanced scent experience with the best longevity.
What are fragrance notes?
Fragrance notes are the individual scent ingredients arranged in a pyramid. Top notes (first 15 minutes) are light and fresh — citrus, green, aquatic. Heart/middle notes (15 min to 2 hours) form the main character — floral, spicy, fruity. Base notes (2+ hours) are deep and long-lasting — woody, musky, amber, vanilla.
What are accords in perfumery?
An accord is a harmonious blend of two or more notes that creates a unified scent impression greater than the sum of its parts. For example, a fougere accord combines lavender, oakmoss, and coumarin. A chypre accord blends bergamot, oakmoss, and labdanum. Accords are the building blocks that define a fragrance's character and family.
What is sillage?
Sillage (pronounced see-yazh) is the scent trail a fragrance leaves behind as you move through a room. A fragrance with strong sillage can be noticed from several feet away, while a skin scent stays close to the body. Projection is related but refers to how far the scent radiates while you're stationary.
Wearing & Applying
How do I make my perfume last longer?
Apply to pulse points (wrists, neck, behind ears, inner elbows) where body heat helps diffuse the scent. Moisturize skin first — fragrance clings better to hydrated skin. Don't rub your wrists together (it breaks down top notes). Store away from heat and light. Layer with a matching unscented body lotion for best results.
How many sprays of perfume should I use?
For most designer fragrances: 3-5 sprays (1-2 on the neck, 1 on each wrist, optionally 1 on the chest). For strong or niche fragrances: 2-3 sprays may be enough. For Extrait concentration: 1-2 sprays. Always adjust based on the setting — less for office, more for outdoors or evenings.
Why does perfume smell different on me?
Your skin chemistry — pH level, diet, medications, hormones, and body temperature — all affect how perfume develops. Oily skin tends to hold fragrance longer and amplify certain notes. Dry skin may cause faster evaporation. This is why testing on your own skin is essential before purchasing.
Can I layer different fragrances?
Absolutely. Fragrance layering means wearing two or more scents together to create a unique combination. Start with complementary scent families: vanilla + citrus, wood + spice, or floral + musk. Apply the heavier, darker scent first as the base, then the lighter scent on top. Many brands (like Maison Margiela Replica) are designed specifically for layering.
Buying & Collecting
How do I find my signature scent?
Start by identifying scent families you enjoy: fresh, woody, floral, oriental, gourmand. Try samples and decants before committing to full bottles. Consider your lifestyle, climate, and occasions. Visit perfume counters and test 3-4 fragrances max per visit. AI tools like ScentWise can match your preferences, style, and personality to specific fragrances.
What is a fragrance dupe?
A dupe is an affordable alternative that smells very similar to a more expensive fragrance. For example, Armaf Club de Nuit Intense Man (~$30) is a popular dupe for Creed Aventus (~$445). Dupes share similar note profiles but may differ in longevity or nuance. Use our Dupe Finder to discover affordable alternatives.
What is a blind buy?
A blind buy is purchasing a fragrance without smelling it first, based on reviews, notes, or recommendations. Low-risk blind buys are crowd-pleasers with high approval ratings (like Bleu de Chanel or Versace Eros). ScentWise rates blind buy risk for every recommendation to help you decide.
What is the difference between niche and designer fragrances?
Designer fragrances are made by fashion houses (Chanel, Dior, YSL) for mass appeal and wide availability, typically $50-200. Niche fragrances are created by dedicated perfume houses (Creed, Maison Francis Kurkdjian, Byredo) with more unique, complex compositions, typically $150-500+. Neither is inherently "better" — it depends on your preferences and budget.
Does perfume expire?
Most perfumes last 3-5 years when stored properly. Heavier, amber-based fragrances can last even longer. Signs of expiration include color darkening, altered scent (sour or metallic), or skin irritation. Light, citrus-forward fragrances tend to degrade faster than woody or oriental ones.
How should I store my perfume collection?
Store perfumes upright in a cool, dark place — ideally 15-20C (59-68F). Avoid the bathroom (humidity and temperature fluctuations). Keep bottles sealed when not in use. A bedroom drawer, closet shelf, or dedicated cabinet is ideal. Never store in direct sunlight or near radiators.
