Ever wonder how cologne works? The oils and essences that make up a fragrance, referred to as "notes," are slowly warmed and then react to your specific body chemistry.
Noticed immediately, but dries out in 15 minutes. (Example: herbs like coriander.)
As the top note fades, this scent lasts about an hour. (Example: citrus like tangerine or grapefruit.)
The heaviest layer, which clings to the skin for the rest of the day. (Example: tobacco, musk or patchouli.)
An industry term for the time it takes for a fragrance to react with your skin and for the heart of the scent to kick in. This is why a scent smells different on each person.
