Projection refers to how far a fragrance radiates outward from your skin — a fragrance with strong projection can be noticed by people standing near you, while a soft-projection fragrance stays closer to the skin. Longevity refers to how long the fragrance remains detectable over time, regardless of how far it projects. A fragrance can have soft projection but very long longevity, or strong projection with only moderate longevity. Understanding both helps you choose the right fragrance for the right occasion.
