Have you ever used a Biore pore strip? This mask will have the same effect (not as harsh on your skin) on your entire face. It is really simple to do and you already have everything you need in your house right now. I started doing these a few years ago and it's a nice mask to have in your back pocket whenever you need to freshen up.
Grab a Kleenex and separate the layers (usually there will be two). Carefully rip one layer in half, the other layer you can probably keep in one piece. Get some egg whites (about a tsp. You don't need much, a little goes a long way) and a small brush.
Start with one of the pieces you tore in half. place it on your forehead so it covers as much skin as possible. Dip your brush in the egg whites and start to paint over the Kleenex on your forehead. The egg whites will act like a glue to hold the Kleenex onto your skin. Don't paint over your eyebrows or hairline.
Continue to do this over the rest of your face. Move the Kleenex around so everything is covered and be sure to poke holes so you can breath! I tend to leave my mouth covered and just don't paint over my lips. If you know you'll be speaking, make sure to tear out a space.
It will take about 10-15 minutes for the egg whites to dry. If you want to speed up the process, feel free to blast some cool air with your blow dryer.
When everything is dry, peel the Kleenex off. You'll want to wash the egg whites off your face. Let me know how the mask works out for you in the comments!
