How do I choose a sunscreen?

Look for a product with a minimum SPF of 30 to protect against the sun’s ultraviolet B (UVB), or burning, rays. The product should also contain ingredients that protect against ultraviolet A (UVA) rays which penetrate more deeply into the skin and are responsible for premature aging and contribute to the development of skin cancer. Sunscreens that are labeled “broad‐‐ spectrum” help protect against both.
