Wear-time guides
How long does perfume oil last
Perfume oil has no fixed wear time from its carrier alone. The composition, amount applied and conditions affect the experience, and the time a scent remains close to you differs from how noticeable it is around others.
A HUME Fragrance buying guide

Identify the finished product
A cosmetic perfume oil is different from a raw fragrance material. Read the exact formulation description and instructions before comparing performance claims.
Avoid drop-to-spray comparisons
A dropper or roller and an atomizer may deliver different quantities. Record the actual application rather than assuming a numerical conversion makes the test equivalent.
Check your preferred outcome
Evaluate enjoyment and presence through your intended use. An oily carrier is not proof of better duration, greater projection or a more natural formula.
Try this before you buy
Record the oil's actual applicator and later impression without treating a spray perfume as a directly equal dose.
