Fragrance composition is a blend of volatile materials that evolves over time. Concentration labels such as eau de toilette and eau de parfum are useful but not a universal measure of strength or longevity; formulas differ and brands use terms differently.
02
How to choose
Test on a fragrance strip first, then on skin if appropriate. Let it develop for several hours and avoid testing too many scents at once. Consider climate, workplace, projection preference, bottle size and refill availability. Buy sealed product from a reputable source and keep the receipt.
03
The Asia lens
Heat can increase perceived projection and change how a fragrance wears. Test it outdoors and indoors in the climate where you expect to use it. For online or cross-border purchases, check local rules for shipping alcohol-based fragrance and estimate the full delivered cost.
The short answers
Frequently asked questions
Which perfume concentration lasts longest?
Concentration is not a reliable universal ranking of longevity. Formula, skin and temperature all matter; test the exact fragrance.
How should perfume be stored in a humid climate?
Keep it capped in a cool, dark place away from windows, bathrooms and heat sources.
Can perfume expire?
It can change with time and storage. Watch for major changes in colour, smell or performance and follow seller/manufacturer guidance.
