Sillage vs Projection: The Difference
Sillage and projection – what is the difference?
In perfume forums the terms sillage and projection are often used synonymously. Yet they describe different phenomena. As an Extrait de Parfum maker we explain the difference.
Projection – how far your fragrance reaches
Projection describes the radius within which your fragrance is perceptible. A strongly projecting perfume fills a room before you have entered it. Al Hayvaan is a prime example of excellent projection: the combination of oud, amber and musk creates a present, room-filling aura.
Sillage – the scent trail behind you
Sillage (French for "wake") is the scent trail you leave behind when you cross a room. A perfume can have low projection but excellent sillage – it surrounds you discreetly yet leaves a lasting trail.
How do raw materials influence sillage and projection?
Projection boosters
Spices, fresh citrus notes and certain wood notes project strongly. Oud is known for its exceptional projection – especially in high concentration.
Sillage masters
Ambergris and musk are the kings of sillage. They cling to skin and clothing and create a subtle, long-lasting scent trail. Musk al Khurasan demonstrates this perfectly.
Concentration and its effect
A higher concentration does not automatically mean stronger projection. Many Extraits sit closer to the skin than EDTs but offer superior sillage and longevity. Tonkin Sunset shows this phenomenon: moderate projection, but a sillage that is still perceptible hours later.
Wearing tips
For more projection: spray on clothing and pulse points on the neck. For more sillage: spray on wrists and into the hair. Combining both techniques maximises your fragrance presence.
