Cut off pomegranate crown, and score rind in sections, without cutting all the way through. Place in a bowl of water for 5–10 minutes. Break rind away from seeds, which will sink; strain seeds. In a food processor, combine 2 tablespoons seeds and 1 cup uncooked oatmeal. Transfer to bowl; stir in 2 tablespoons honey (an antiseptic) and 2 tablespoons buttermilk. Apply to face for a few minutes, then rinse. For rough patches (like elbows), add 3/4 cup turbinado sugar.
