Planning fragrance quantity
How long will a 5ml perfume decant last
A 5ml decant does not have one fixed lifespan in wears. The actual container and your application routine determine consumption, while the exact fragrance determines the scent experience you assess.
A HUME Fragrance buying guide

Record the applicator
Spray and dab formats deliver differently. Equal counts from two containers are not necessarily equal amounts.
Keep source identity
Save claimed maker and version so usage notes remain linked to the correct decant.
Separate storage concerns
Follow the supplier's container guidance rather than using an estimated wear count as an expiry date.
Try this before you buy
Record the decant's identity, applicator and actual wearing frequency before estimating whether more is needed.
