How Much Sunscreen Is Enough?

Choose a broad-spectrum sunscreen with SPF 30 or higher and apply it generously to all exposed skin. Many people use less than they need, so take time to cover the face, ears, neck, and hands.

Apply sunscreen before sun exposure and reapply at least every two hours outdoors, or after swimming or sweating. Follow the product label for specific directions.

Sunscreen works best alongside shade, protective clothing, and avoiding prolonged midday sun.
