Sun exposure is the cause of most of the changes to our skin that we believe is a normal part of aging. The sun’s UV light damages fibers in our skin, called elastin, over time. When these fibers begin to break down, a person’s skin can stretch, sag, and lose the ability to go back to the same way it was. The time spent in the sun also causes skin to tear and bruise more easily, which can mean it takes longer to heal. You may not see the effects of sun damage on your skin when you’re young, but it will show up later in your life as you age.
Signs of sun damage to skin include:
Wrinkles
Age spots
Freckles
Discoloration
Sagging skin
