It reduces it, yes. Cold air and cold skin both slow down how quickly fragrance molecules evaporate and travel, which means the same perfume that projects generously in summer can feel noticeably closer to the skin in winter.

Why cold has this effect

Projection depends on evaporation, molecules leaving your skin and reaching the air around you, and evaporation is a temperature-driven process. Cold skin and cold surrounding air both slow this down considerably, which is exactly why a fragrance can feel like it’s “disappearing” faster in winter even if it’s technically lasting the same amount of time on your skin, it’s just not reaching other people’s noses as readily.

How to compensate in cold weather

  • Apply slightly more generously than you would in summer
  • Choose richer, heavier concentrations, eau de parfum over eau de toilette
  • Apply to warmer areas of skin, like the neck and chest, where body heat helps the scent along
