Overview

• Sunscreen should be applied generously: three tablespoons for the body and one teaspoon for the face to achieve the labeled SPF protection.
• Reapplication is essential every two hours and after sweating, swimming, or physical activity to maintain effectiveness.
• The Bundesamt für Strahlenschutz advises using sunscreen when the UV index reaches 3 and avoiding midday sun exposure when it exceeds 8.
• Babies, toddlers, and fair-skinned individuals require extra precautions, such as avoiding direct sunlight and using physical sunscreens.
• Consumers should check sunscreen expiration dates and use products within 12 months of opening to ensure efficacy.
