What causes wrinkles around the eyes?
Your skin is made up of layers. While you notice the effects of aging on the surface of your skin, the process actually begins deeper down. In the middle layers of your skin, collagen works with other proteins, like elastin, to create new skin cells and repair any damage.
The more collagen your body produces, the more frequently the top layer of skin is replaced, keeping your skin youthful and wrinkle-free. As you get older, your body makes less collagen. Production begins to drop in your 20s, and by your 40s it’s significantly reduced and continues to decline.
Around the eyes where the skin is thin, this reduced collagen production leads to wrinkles and fine lines appearing sooner than they do in other areas. That’s why you may notice fine lines and crow’s feet as your first signs of aging.
