Same formula. Same concentration. Three placements. Three different experiences for you and for everyone around you. Placement is not preference. It is geometry.
VARIABLE A | INNER WRIST
The inner wrist projects forward and upward as you move — the fragrance travels in the direction of your gestures. At close range (handshakes, conversations) this is the most socially proximate placement. The wrist is also constantly in motion, which generates small thermal differentials and periodic bursts of projection as the skin flexes and releases. Best for: close-contact environments, testing, professional settings where a contained projection is appropriate.
VARIABLE B | BASE OF THROAT / NECK
The throat sits at the centre of your personal space radius and projects in all directions — forward toward people you face, sideways, and upward into your own airspace. Body heat from the neck and carotid arteries drives consistent upward thermal convection, carrying fragrance molecules into the air above and around you. This is sillage geometry: the trail you leave as you move through a space is primarily driven by neck application. Best for: social events, close conversation, environments where sillage matters.

RESULT
Wrist = directed, close-contact projection. Neck = omnidirectional sillage, the trail you leave. Chest (inner sternum, where the pectoral muscles generate heat) = the most sustained, slow-release placement — fragrance rises in a column from the chest through the collar and into the space in front of you over hours. For maximum all-day performance from a single application: chest. For maximum first-impression impact: neck. For evaluation and testing: wrist
WHAT TO DO INSTEAD
Run this test with three sprays of the same EDP: one inner wrist, one base of throat, one inner chest below the collar. Evaluate projection at 30 minutes (ask someone to stand 1 metre away — not you). Evaluate longevity at 6 hours. The wrist will be the most personally perceptible. The neck and chest will determine how others experience the formula.
