Olive oil. Apply one tablespoon to your face, let sit, and pat off with a towel.
Cucumber and oatmeal. Mix in a blender until you get a consistency you like, then apply to your skin. (You could even do the little cucumber slices over your eyes, too!)
Honey. Rub a light layer of honey into your skin, and let it sit for 30 minutes. Rinse off with warm water.
Egg whites. Separate the yolks out of one or two eggs, beat the whites a bit, and apply to your face. You should feel your pores tighten up.
