It's emerged that one in five men steal their partner's beauty products, costing up to 200 euro a year.
The survey by beautyheaven.com.au found the item that's nicked most often is moisturiser, but shampoo and body wash are also high on the list.
It's emerged that some men even experiment with leg wax, eyeliner and hair spray.
The survey found that 90 per cent of women are happy for men to steal their stuff, because it encourages them to look better.
