Girls Night out {well not really...but you get the point}: Facial Masks

This morning I made a homemade facial mask for me, my little sister, and my mom. i used an egg whites and lemon recipe:
2 egg whites
1teaspoon lemon juice
Only I didn't have lemon juice! So I had heard that you can substitute it with {1/2 of what is required of the lemon juice}white vinegar. But I doubled everything cause it didn't look like much. So I ended up with 1teaspoon of white vinegar.And then, because it didn't look thick enough I added brown sugar till it did!
