Who needs Botox when you have bananas? That's right: You can use a banana as an all-natural face mask that moisturizes your skin and leaves it looking and feeling softer. Mash up a medium-sized ripe banana into a smooth paste, then gently apply it to your face and neck. Let it set for 10-20 minutes, then rinse it off with cold water. Another popular mask recipe calls for 1/4 cup plain yogurt, 2 tablespoons honey, and 1 medium banana.
