As we are approaching the summer months, it is important to use sunscreen daily, but to make sure we use it correctly. Sunscreen is the most important step in our daily routine to prevent premature aging and skin cancer. This article will go over some tips on using sunscreen properly. Apply sunscreen SPF 30 or higher and make sure it is broad spectrum (protects against UVA and UVB). Reapply every 90 minutes. Wear water-resistant and sweat-resistant sunscreen if you will be outdoors, on the beach, or swimming. Don’t forget your ears, lips, tops of feet, and hands, as these are common areas people miss during application and are common areas for skin cancers. Apply 15 minutes before going outside to ensure the sunscreen has absorbed into your skin. Make sure your sunscreen is not expired, as expired sunscreen is not as effective in protecting your skin. Avoid leaving sunscreen outside in high temperatures for prolonged periods, as the heat can slowly break down some of the active ingredients that protect your skin. If you have sensitive skin, rosacea, or acne-prone skin, consider purchasing mineral sunscreen over chemical sunscreen. Use enough sunscreen, as for full protection, adults typically need one ounce (a shot glass full) to cover the entire body. Cloudy skies do not mean there are no UV rays, as up to 80% of UV rays can pass through clouds, so sunscreen should still be applied even on overcast beach days.

Sunscreen is one of the simplest ways to protect your skin—but small mistakes can significantly reduce its effectiveness. By applying enough, reapplying regularly, and covering often-missed areas, you can greatly reduce sun damage. Apply your sunscreen this summer to prevent skin cancer and keep your skin healthy and beautiful!
