Many people only wear sunscreen during summer, but UV rays are present all year. SPF, or Sun Protection Factor, indicates how well a sunscreen protects against UVB rays. An SPF of at least 30 is recommended for daily use. Broad-spectrum sunscreens protect against both UVA and UVB rays. Regular use reduces the risk of sunburn, premature aging, and skin cancer. Even on cloudy days, applying sunscreen is a critical step for maintaining long-term skin health.
