What is "good sunscreen"? Good sunscreen is a lotion, spray, gel, or other topical product that helps protect the skin from damage caused by the sun's ultraviolet (UV) rays.
Sunscreen is important because it can help prevent skin cancer, premature aging, and other skin problems. It is especially important to use sunscreen when you are outdoors, even on cloudy days. There are many different types of sunscreen available, so it is important to choose one that is right for your skin type and needs.
When choosing a sunscreen, it is important to look for one that has a broad-spectrum SPF of 30 or higher. Broad-spectrum sunscreen protects against both UVA and UVB rays.
