In your 30s or 40s you may notice that you no longer tan. Instead, your skin looks speckled and splotchy and may itch after being in the sun. This is nature’s way of reminding you that sun damages skin. The light spots are where the skin’s pigment cells have been killed by the sun. The dark spots are where the pigment cells have tried to multiply to protect your skin from the sun.
Alas, now your skin looks much older than if you avoided the sun. This is one of the symptoms of “photoaging” and one of the signs that your skin is at increased risk of developing skin cancers.
Apply sunscreen, wear protective clothing, and avoid sun exposure in the middle of the day. Protect your skin from the sun!
