Are you protecting your skin from the summer sun? Choosing the right sunscreen is key to preventing sunburn, premature aging, and skin cancer. Start by selecting a broad-spectrum sunscreen—this means it guards against both UVA (aging) and UVB (burning) rays. Look for a Sun Protection Factor (SPF) of 30 or higher. While higher SPFs offer slightly more protection, the benefits level off above SPF 50. Next, check the ingredients. Physical (or mineral) sunscreens with zinc oxide or titanium dioxide are great choices. They sit on the skin’s surface to deflect UV rays and tend to cause less irritation than chemical options. Apply generously and reapply every two hours.
