Why does perfume smell fade?

Answer: Scent molecules evaporate

Scent molecules evaporate ✓ — Correct! Perfume contains volatile molecules that evaporate into the air. As they spread out and dissipate, fewer reach your nose. Top notes fade fastest, while base notes linger because they evaporate more slowly.

Body heat destroys perfume molecules — Wrong. Body heat doesn't destroy perfume—it actually helps disperse the scent. Fading happens because molecules evaporate into the air.

Light breaks down perfume — Wrong. Light can degrade perfume in bottles, but worn perfume fades primarily through evaporation, not light exposure on skin.
