What is Sillage? Understanding the Scent Trail You Leave Behind

Have you ever walked into a room and smelled someone who was there five minutes ago? That is sillage. Derived from the French word for 'wake' (like the trail left by a boat in water), sillage is the scent trail left by a fragrance wearer as they move. It is the ghost of the fragrance, lingering in the air long after the person has departed.

These terms are often used interchangeably, but they are very different. **Projection** is how far the scent travels from your skin while you are standing still. It’s the 'bubble' around you. **Sillage**, on the other hand, is about the trail left in motion. A fragrance can have low projection (sitting close to the skin) but high sillage (leaving a long, lingering trail behind you).

Sillage is determined by the volatility of the molecules used in the fragrance. Heavy base notes like musk, oakmoss, and ambroxan tend to hang in the air longer, creating a more pronounced trail. This is why fragrances like **Baccarat Rouge 540** or **Creed Aventus** are famous for their sillage—they use heavy, persistent molecules that don't just disappear into the atmosphere.

If you want to leave a memorable trail, spray the back of your neck or your hair. As you walk, your movement will catch the air and pull the scent behind you. If you want to keep your scent private (low sillage), spray your chest or under your clothes. This keeps the scent trapped against your body heat without allowing it to trail into the air.

The best way to test a fragrance's sillage is to spray it on a friend and have them walk past you. Or, better yet, use one of our 10ml atomizers to test a fragrance in different environments—office, outdoors, or a crowded restaurant—to see how it trails.
