Age-proof your eyes with this easy (and cheap!) under-eye mask. Soak two cotton balls in a bowl of ice-cold whole milk. Squeeze them out and place one over each eye. When your skin has warmed up the cotton balls, soak two more and repeat for up to 15 minutes. The cold milk constricts blood vessels and de-puffs eyes, while the fat moisturizes and replenishes dry skin and the lactic acid helps remove dead cells to soften fine lines!
