Perfume typically stays good for 3 to 5 years after opening, so your 8-month-old Dior is still in its prime. The bathroom cabinet is actually not ideal though - heat and humidity from showers can degrade it faster, so a cool, dark closet would be better. You can tell it's gone bad if the color darkens significantly, it smells noticeably different (usually more vinegary or flat), or the scent doesn't project as well as it used to. Since you've only had it 8 months in a reasonably protected spot, it should be fine - just move it somewhere cooler and drier going forward.

Your 8 months is nowhere near the danger zone - Dior fragrances usually hold up for several years if stored right. The bathroom cabinet thing though is legit a problem; heat and steam from showers will absolutely break down the fragrance faster than you'd think, so if you've been keeping it there you might notice the scent getting thinner or shifting slightly, but it's probably still totally wearable. The real tells are if it smells noticeably different (off, vinegary, or just weaker), the color has darkened significantly, or the cap got loose and let air in. Move it to a cool, dark closet or drawer now and it should be fine for years.

How often are you actually using it - spraying it daily or just occasionally? Eight months is still plenty safe, but the bathroom storage is genuinely sketchy since humidity and heat cycles from showers can oxidize fragrances faster than most people realize. If you're noticing the scent smells noticeably thinner, more vinegary, or just muted compared to when you first opened it, that's degradation, but honestly the best test is just comparing how long the scent lasts on your skin now versus when it was fresh. Moving it to a cool, dry closet or bedroom drawer would buy you years of better performance going forward.

Dennis69 asker I spray it maybe 2-3 times a week, so pretty light use. Thanks for the humidity heads-up - didn't realize bathrooms were that rough on fragrance.

eight months is really nothing to worry about - perfume degrades way slower than people think, and dior fragrances are built to last. that said, bathroom storage is genuinely risky because of the humidity cycles, so here's what i'd do: move it to a cool dark closet or drawer somewhere else in your house, and if you want to know if it's actually degraded, do a smell test by comparing it to a fresh tester at a department store (that'll tell you immediately if the scent profile has shifted). the easiest way to tell somethings genuinely off is if the color darkens noticeably or it smells vinegary instead of like perfume.

Eight months is totally fine for your Dior - you're nowhere near any degradation zone with that timeline. I'd actually push back a bit on the bathroom storage concern though, since it depends on your setup. If your cabinet stays relatively cool and you're not running steamy showers right next to it constantly, you're probably okay. The real killers are direct sunlight, extreme heat swings, and keeping it somewhere like right above a radiator. Your scent will smell off if it's gone bad - it'll either smell weaker, smell different (musty or flat), or develop weird notes that weren't there before. Since you're still within that safe window, just give it a sniff test and you'll know.

Does it smell noticeably different than when you first opened it, or is the scent pretty much the same?

Your bottle should be totally fine at 8 months. Perfume is legitimately stable stuff - I had a fragrance sitting around for years that still smelled identical to when I bought it. The real issue is that bathroom storage is genuinely working against you. Heat and humidity from showers create temperature swings that actually break down the fragrance faster than age alone would. It's not going to ruin it overnight, but over time that environment does damage the delicate compounds.

If you want to keep it fresher longer, move it somewhere cool and dry - a bedroom closet, a drawer away from windows, that kind of thing. Direct sunlight is your enemy too, so anything opaque or dark is better. As for telling if it's actually gone bad, if the color looks noticeably darker or the smell seems thin or off compared to how you remember it, that's a sign degradation is happening. But honestly, 8 months in a bathroom? You're probably still good. Just swap the storage spot and you'll get way more life out of it.

Dennis69 asker Nope, smells pretty much the same as when I opened it. Thanks for the storage tip though, gonna move it to my closet.
