Contact lens wearers looking to avoid problems with their vision may want to go easy on out-of-date eye make-up.
"We wouldn"t hesitate to chuck out mouldy or bacteria-ridden food and the same standards should apply to the lotions and potions and that we put on our skin," commented Sara Stern, director of cosmetics at Debenhams.
She was commenting after research from Debenhams showed that 68 per cent of women only replace make-up and skincare when they run out.
The survey showed 89 per cent of women are unaware that product shelf life information exists, do not understand what the symbol means or cannot read the often tiny writing.
This is despite European Union guidelines meaning brands have to state product shelf lives.
Over three-quarters (81 per cent) of women said they go to sleep at least once a week without removing make-up.
Research from Mintel found that only 28 per cent of British women discard make-up, shampoo and shower gel if they smell odd or become discoloured.
