I was so excited to try this that I initially missed the no-water rule (you're not supposed to use water to clean off the magnet), which left me with a very supercharged mess. Not to mention, iron plus water equals rust—and considering this mask is made of iron particles, that combination was not ideal in my sink.

After finally noting that the instructions say to put a tissue or paper towel over the magnet, I was back on track to prep my skin. To get the most out of a magnetic (or any) face mask, it's vital to make sure you wash off all of your makeup and rinse your face with warm water to open your pores.
