"How do you know when an eye primer has expired? Does it start to smell kinda funky?"
Asked by coolsville-n
Hi sc0obysnax, the safest thing to do is to check the number accompanying the Period-after-Opening marker on the back of the package. This states how long the product is expected to stay usable. E.g. 20M means it should stay good for 20 months after opening.
But don’t just use that as an indicator! IN GENERAL, if you’re using a powder pigment or pressed shadow which doesn’t contain any organic fats or binders, it will stay good for an indefinite amount of time.
For everything else, there’s also the:
- Expiry date - check this before you buy, please…. If a product is due to expire 2 months from now, don’t get it.
- Smell/Texture - Some ingredients can change color and separate without actually going bad. For many oil-in-water or pigment-in-water/oil emulsions, just shake it up and you’re good to go. But if the texture has changed to the point where it’s no longer the same product anymore, or if it smells to smell off, OUT it goes.
The rule-of-thumb is: throw it out whichever comes first; the usage date, the Period-after-Opening date, OR the smell and consistency.
It doesn’t matter how much it cost. It will cost a lot more for you to fix your face.
