Any dermatologist will tell you that sunscreen should be your constant companion all year long—but especially in the summer months. This topical product protects your skin from ultraviolet (UV) radiation with physical blockers that either reflect or absorb UV rays—so it pays to always have a bottle in your purse, beach bag, and car. Despite the fact that sunscreen is a necessity, many myths persist about how—and even if—the product works.
“Sunscreen is crucial in preventing sunburn, premature skin aging, and reducing the risk of skin cancer. It is absolutely necessary in every skin type,” explains dermatologist Dr. Divya Shokeen. Research shows that wearing SPF 15 or greater each day can reduce your risk of developing squamous cell carcinoma (the second most common cause of skin cancer) by about 40% while lowering your melanoma risk by 50%. However, the American Academy of Dermatology recommends daily use of sunscreen that’s at least SPF 30.
