I remember the blue mask. I alsways thought that's where Mel Gibson got the idea of the blue face in
Braveheart.
When I peeled off the mask, I had only areas where stuff came out of my pores, like on my nose. The rest was just dead skin cells coming off.
If it was the same for you, you can simply replace the mask with a microderm abrasion scrub to remove the dead skin cells, and use the Biore peel off strips for the nose & forehead.
Now THAT is gross when you peel one of those off and see what was stuck in the pores!
