How to spot products past their prime.
When beauty staples pass their sell-by date
LIPSTICK Your favourite lippy can last up to two years if stored in a cool place, but if it has a strange smell (sour/rancid), throw it out.
MASCARA To decrease the risk of eye infections, mascara should be replaced every three months, even if it has been used just once.
POWDER Loose powder can survive up to three years, but if it's older than that and starts looking dry and cakey, bin it.
EYELINER Eye pencils have a longer shelf life than liquid liner (bin every three months) and can be kept for two to three years.
NAIL VARNISH This will last only a year before becoming thick and cloggy, so don't keep half-used bottles.
