Crow’s feet seem to be the first wrinkles everybody notices at some point during their twenties or thirties. Fine lines around the eyes are notoriously difficult to prevent, not only because our eyes are highly expressive, but also because we’re less likely to want to get sunscreen anywhere near them. A new study out of Japan has shown a third reason the eye area tends to show its age before other parts of the face: it lacks sebaceous glands. Sebaceous glands are the body’s own oil refineries, responsible for lubricating skin, keeping it supple and protecting it from environmental damage. Aside from getting a good eye cream and wearing sunglasses as much as possible to prevent UV injury, scientists emphasize the importance of hydration, regular exercise and adequate sleep.
