Wear-time comparisons
How long do oil perfumes last on skin
An oil carrier does not establish a fixed skin-wear duration. Finished oil perfumes differ in composition and application, and their close-range experience should be evaluated separately from how noticeable they are around others.
A HUME Fragrance buying guide

Read the finished product
A personal perfume oil is different from a raw fragrance or home-scent material. Use only the intended product and its actual directions for a wearing trial.
Avoid equal-dose assumptions
Rollers, dabbers and sprays deliver fragrance differently. An equal number of applications is not a controlled comparison across mechanisms.
Record the outcome you want
You may prefer the applicator, the later smell or a quieter experience. None of those preferences requires assuming oil always lasts longer than alcohol-based perfume.
Try this before you buy
Record carrier and applicator alongside later enjoyment so an oil-format preference is not confused with a duration claim.
