Performance basics
Why does perfume last longer on my friend
A friend's different experience can involve application, setting, product version and perception rather than one proven explanation about your skin. Make sure you are comparing the exact same fragrance and a similar kind of observation.
A HUME Fragrance buying guide

Check the starting facts
Confirm version, dispenser and application method. Equal spray counts from different bottles are not automatically equal amounts.
Separate observer roles
Smelling your own scent and noticing someone else's are different experiences. Record who noticed what rather than assuming both reports measure the same outcome.
Repeat without blame
Use another ordinary trial before deciding the perfume is defective or that one person is unsuitable for it. Personal comfort and enjoyment still matter more than winning a duration comparison.
Try this before you buy
Compare exact version, application and observer before interpreting a friend's report as a product benchmark.
