FAQ
Does cologne expire?
Most fragrances last 3-5 years when stored properly, though some last over a decade. Signs of expiration include darkening color, a sour smell, or noticeably weaker scent. Heat, light, and humidity accelerate degradation. If your cologne smells off, replace it. Our Fragrance Finder helps you discover a worthy replacement.
How should I store cologne to make it last longer?
Store bottles upright in a cool, dark, dry place like a dresser drawer or closet shelf. Avoid the bathroom (humidity) and windowsills (sunlight breaks down fragrance molecules). Keep the cap on to prevent oxidation. Never store cologne in a car. Proper storage can extend bottle life by years.
Is decanting worth it?
Absolutely. Decanting protects your main bottle from light and air exposure, and a 5-10 ml travel spray fits in your pocket for reapplication. Use glass atomizers rather than plastic, which can interact with fragrance oils. Our Sprays per ML Converter helps you figure out exactly how many sprays fit in your travel size.
