The Batch Code on your MAC product that you just purchased ended in a 6, meaning it was made in 2006? Or are the products fine until you open them, and then the 24 month toss rule goes into effect?
great question. i would think that it the clock would start once the product is made (kinda like food- u would use milk that had only been in ur fridge for a day and expired 2 days ago, right?) but its makes sense that it wouldnt start counting down until after the first use cause thats when the contamination that ruins the product happens. Ugh I have no idea. But I know the waxes will break down no matter when u start using it. Yeah still no clue...
i guess for powder things it is ok, i just bought a hepcat that was made in sept '06.
i called their customer service about a couple of cream blushes and i was told that the usual lasting time is whatever is on the container plus a year...
well i have some that are older than that, but i'm not too concerned. could be because i mainly use mac for their eyeshadows. lipsticks/lipgloss - yea i would be. but i always smell for that vanilla scent.
but i think the date could matter for liquid products - like foundations? just a thought i don't think i'd be comfy with using really old foundation lol
i got a jar of green brown pigment from a pro store a few months ago, and the batch code says AB3. i thought about returning it, but could not find the receipt, so i kept it. so far i haven't had any problem with it
I find that my powder products stay good if stored properly in moisture free environment and wiped after each use,... I have a limit and a phase eyeshadow in the screwtops still perfect and working like new. Now lip products are a different story. I bought a soft and slow what a couple months ago and I opened it last week and it reeked. I don't think I even used that three times. I guess it just depends,.. once opened go by the packaging and also by smell bc it could go bad sooner.
I returned a Studio Tech because it cracked after just a few weeks. The MA told me that sometimes product gets misplaced, then reshelved. She looked at and said "It's old" even though I just bought it. It happens.
I've recently gotten products from 06 from our Mac store. I know they restock often so they must be coming from the factory with that date.
I never noticed them to be icky.
I was told that if your product goes south within a resonable amount of time..to return it and get a new one. Things happen. If you can't get help at the counter, call CS at Maccosmetics.com
