Old nail polish..when is it too old to use?

If nail polishes last forever.. then I wonder why they have the little shelf life thingie.. and also why it smells so sour after a couple of years later? I figure that it actually is bad and even though it might look safe to put on your fingers.. I mean, they don't put the shelf life on the bottle for nothing.
 
Great info, thanks everyone! I've used thinners before, but I feel that polish doesn't dry well and doesn't have a shiny finish or doesn't completely harden. I always thought it was cos the polish was old. But maybe I was putting too much thinner or using one with too much alcohol. I have so many nail polishes that I've tossed since I thought they may damage my nails cos they were old. I'm going to reevaluate for sure!

I might not be checking correctly but I can't find a shelf-life print on any of my nail polishes. Not on the sticker, bottle or cap. What kind of code am I looking for? :confused1:

Anyway, as far as the sour smell goes, I have tremendously old polishes that still smell normal to me. I close them super tight though, maybe that makes a difference?
 
Well, if the thinner doesn't work, I highly suggest looking into Zoya's polish exchange if you haven't already. Sure beats throwing them out and getting nothing in return for it. ;)
 
At the back of some OPI's and china glazes there is this symbol of what looks like a container with an open lid with a number (for my nail polishes it's either a 24 or 36) with an "m" beside it. That means that it's good for only 24 or 36 months, or 2 or 3 years. This symbol with the numbers are also at the back of most cosmetics (ie. smashbox, MAC). Here's a pic:

So.. I think that there's a reason they put these "Period After Opening" symbols behind nail polishes for a reason. Maybe the chemicals breakdown and can become toxic, I don't know. So I'm just going to be cautious and if my polishes turn old and funky, they will be chucked down the trash bin.

Ah, I see, didn't know about that symbol. Thanks so much for posting a picture, I was looking for a date! :lol:

I think beyond that period the consistency of polish is certainly changed, but I'm fine with using thinner as a fix for that. If it were lipstick or moisturizer I would definitely chuck it, but I'm not too concerned with absorbing chemicals through my dead nail plates. I use some big-3 products too. :P

Thank you for explaining the symbol to me though! I do see it on my bottles.

I've done two exchanges and it's awesome! If you ladies are throwing out your polishes, definitely do it. Zoya rocks and it's basically 50% + free shipping!

It's still good right now.
 
Yeah, I noticed OPI puts that period after opening symbol on their bottles (it's 24M in their case). I have no idea why they do that. Sometimes, I wonder if companies want us to believe that products have a certain shelf life, so we will toss them out and buy more.

Or because they just can't stand by the product's consistency after that point? My Nail Tek Extend says I can keep refreshing polishes forever, and I like the sound of that. :biggrin:
 
I have a couple that would be approaching 15 years old - I think I should get rid of them - they still seem fine, but honestly, if I haven't used them up yet, will I ever?
