Toiletries and travel-size cosmetics packed in a bag for travel

Yes, heat accelerates the chemical breakdown of fragrance ingredients, so a bottle exposed to consistently hot conditions, a holiday destination, a hot car, direct sun, will generally degrade faster than one kept in a cool, stable environment.

Why heat is one of perfume’s biggest enemies

Warmth speeds up oxidation and other chemical changes within the formula, which is exactly why perfume storage advice consistently points towards cool, dark places rather than bathrooms, cars or windowsills. A holiday in a genuinely hot climate, especially if the bottle sits in luggage in a hot car or a sun-exposed hotel room for an extended period, can noticeably shorten a fragrance’s usable life compared to normal home storage.

How to protect a bottle while travelling somewhere hot

  • Keep it in your hotel room rather than a hot car boot
  • Store it away from direct window sunlight, even indoors
  • Consider a smaller travel size rather than exposing a full bottle to the whole trip’s conditions
