In a small mixing bowl, use a fork to mash half of a ripe banana into a lump-free pulp.
Mix in 1 teaspoon of milk and 1 tablespoon of ground oatmeal. Combine ingredients thoroughly.
Wash your face with lukewarm water to open pores and pat dry with a soft towel. Using clean fingers, rub the mask into your face in a circular motion. Apply the mask in a slightly thick layer so it has time to sink in.
Keep your mask on for 10-15 minutes, and then wash your face with warm water without soap. Splash cold water onto your face to close your pores and pat dry with a towel.
