This is Paul Janench with a Treasure Coast Essay about sunburn. This is the time of year when we are the most vulnerable. And I don’t mean just fair-skinned, freckly people, like yours truly, but all of us – even those with dark skin. Sunburn is not only painful, it can cause wrinkles and skin cancer. I love to be on the beach or on the water. But in the summer I stay in the shade from mid-morning to mid-afternoon. My dermatologist told me that even then I should apply lots of sunscreen. He recommends a spray with an SPF of at least 70. Apply it twice, letting it dry between layers. Re-apply it every 2-to-4 hours. And wear a hat.
