Don’t share your make-up!

While 99 per cent of bacteria are harmless, when it comes to make-up, particularly eye make-up, you need to be very careful.

Never, ever share mascara or eyeliner or shadow as while your body is accustomed to your own (sometimes disease-causing) bacteria, another person’s can be a different story and give rise to infection. Ditto with razors, particularly if the skin surface is broken.
