Turns out, you're not alone if you find yourself hoarding old makeup (even though you know it's super gross and could lead to potentially deadly illnesses).
A new survey by cosmetics brand Stowaway revealed that 80% of makeup users continue to put expired products on their face - even though they're aware it's gone off.
This is more than likely because 75% of the 4,052 women aged 25-50 who were questioned by the researchers don't use up their makeup - not just before it expires, but ever.
Makeup artist Xavia Somerville told HuffPost UK Style that the expiration date on makeup isn't just there to make you buy more.
"The ingredients can react and change over time and old makeup can provide a breeding ground for germs, this can mean dermatitis, bumps and blemishes," she said.
"Expired makeup should really be thrown away - your face will thank you."
Mascara: Bin after three months.
Eyeliner and eyeshadow: Has a shelf life of six to 12 months, liquid products expire faster.
Lipstick: Keep for up to 18 months.
Foundation, powder and blusher: Lasts around a year, but check the bottom of the container as there's usually a number indicating how many months it will last for after opening.
To rev up your makeup hygiene even more, make sure you clean your makeup brushes frequently - here's how often you should do it.
