Cosmetics are not meant to last forever!
Bacteria and mold will start to grow after a certain period of time. Do you really want to be putting mold on your face?
I’m sure you’ve seen the period-after-opening symbol on some cosmetics. This little graphic lets you know how long it’s safe to use a product after it’s been opened. I wish it was mandatory that all beauty products must be labeled with a PAO! Because some are not, I have a few guidelines I like to follow!
So with things like mascara and eyeliner, I typically don’t keep them too long because the eyes are rather sensitive and ain’t nobody got time for eye infections! Making sure you sharpen your eyeliner pencils before each use will definitely reduce the risk. Lip products, I typically keep for a year or less, it just depends! I’d rather not ingest expired, bacteria-filled lipgloss. Ya feel?
With any cream/liquid products, signs that they need to be tossed include a change in color, scent, consistency, or texture. If a powder face/eye product becomes chalky and is less pigmented than it used to be, it’s time to throw it out. By using clean brushes/tools/fingers, always keeping the products sealed and in a cool, dry place out of direct sunlight will keep your products from going bad.
If I’m unsure of how old a product is, I’ll check my Sephora purchase history. Now, this is nerdy AF, but this cosmetic calculator can tell you exactly how old a product is . All you have to do is put in the batch code/lot number and you’ll know!
One thing you do need to be extra careful of is SPF! Always make sure that your sunscreen isn’t expired before you apply it unless you want a surprise burn later on!
