It's amazing how quickly mascara can transform from being a brilliant lash-lifter into an almost useless makeup tool only good for one thing - creating inky black clumps.
Her top beauty tip? How to revive mascara.
"Remove the lid and brush, then place the open tube in your microwave next to a cup of water for humidity," Mariani says.
"Microwave on high for five seconds to loosen up the contents and get a couple more weeks of luscious lashes."
Her microwaving advice doesn't stop there either. Fans of juicing and smoothie making might also want to note the following recommendation from Mariani.
"A quick blast will soften the cellular walls of the fruit - allowing you to extract every last bit of juice from oranges, lemons, limes and grapefruit."
Last but not least, there's a tip for drying tights asap too.
"A quick blitz on a high setting for a maximum of 30 seconds (stop the oven and check the tights every ten seconds) will leave them bone dry and ready to wear," Mariani suggests.
You'll never wear damp tights again - but remember, not everything is microwave-proof and do be careful when dealing with hot temperatures.
