If you ever find your face on the oily side during a night out and your face powder is nowhere to be found - head to the toilets! The toilet seat covers that you often find in restrooms work incredibly well at absorbing oil. Best of all, they are free!
However, if this tip just doesn't do it for you, invest in a handbag-friendly pack of blotting papers. If you keep them in your bag at all times, you will never be oily and alone again!
I love Bobbi Brown's refillable faux-leather blotting paper case (£17.00 John Lewis / $20.00 Nordstrom). The powder-free blotting papers are amazing at absorbing excess oil and perspiration and the gorgeous case even contains a mirror! What's not to love?!
