What projection means in fragrance
Projection describes how far a fragrance projects or radiates from the person wearing it into the surrounding space. High-projection fragrances are detectable to others across a room; low-projection fragrances — sometimes called "skin scents" — are perceptible only to someone standing very close.
Why projection isn't the same as intensity
A fragrance can be very intense and concentrated while projecting closely to the skin. Ambroxan-heavy fragrances, for example, often create a very intimate, skin-close effect even at high concentrations. Conversely, lighter fragrances with highly volatile aromatic materials can project significantly for a short time even though they lack longevity.
Factors that affect projection
- Molecular volatility: More volatile molecules project further but dissipate faster. Heavy, resinous materials stay close to skin.
- Concentration: Higher concentrations typically improve projection, particularly in the opening and middle stages.
- Application points: Applying to pulse points (where skin is warm) increases projection compared to cooler areas.
- Body heat: Warmer body temperature, warmer weather, or warmer application areas increase projection. This is why the same fragrance often projects more in summer than winter.
- Amount applied: More sprays increase projection up to a point, after which the result becomes overwhelming rather than more projected.
Projection in context
High projection is desirable in some situations (an evening out, a large space) and inappropriate in others (a closed office, close quarters). Understanding a fragrance's typical projection helps you choose how much to apply and when to wear it.
When SCNTMIX analyses a fragrance combination, projection is assessed as part of the performance breakdown — and a layered mix can project differently than either fragrance does alone.
