Yes — repeated temperature swings between hot and cold stress the formula more than steady storage does, even at a slightly warmer constant temperature, so it’s worth avoiding habits like leaving a bottle in a hot car and then bringing it straight into an air-conditioned room, or moving it in and out of a fridge regularly.

Why the swings matter more than the extremes alone

Rapid temperature changes can cause condensation inside the bottle, accelerate the breakdown of delicate fragrance compounds, and stress the seal or cap over time in a way that steady storage at a slightly less-than-perfect temperature generally doesn’t. This is really the underlying reason travel with perfume needs a bit of care, and why a bottle kept in one stable spot at home tends to last noticeably longer than one that’s frequently moved between very different conditions.

  • Avoid leaving perfume in a hot car and then bringing it into a cold, air-conditioned space
  • Don’t move bottles in and out of a fridge repeatedly
  • A single, stable storage spot beats frequent temperature changes even if it’s not perfectly cool

Checked airport luggage, which sits in unpressurised, temperature-variable holds during a flight, is a good example of exactly this kind of swing, which is one reason frequent flyers often prefer smaller travel bottles they can keep with them rather than packing full bottles repeatedly.
