How to Use Sunscreen

Proper sunscreen application is crucial for protecting your skin from harmful UV rays. Here's how to do it effectively:

SPF: Select a broad-spectrum sunscreen with an SPF of 30 or higher. This protects against both UVA and UVB rays. [Many sources, including the American Academy of Dermatology (AAD), recommend this.]
Type: Choose a formula you like – lotions, creams, gels, or sprays are all effective. Water-resistant sunscreen is best for swimming or sweating.

Application

Timing: Apply sunscreen at least 15 minutes before sun exposure to allow it to fully absorb. [FDA and several other sources recommend this.] Some experts even suggest applying it 30 minutes before going outside.
Amount: Use a generous amount. Think about covering all exposed skin. A good rule of thumb is about a shot glass full for your entire body. [This is consistent across multiple sources highlighting the importance of liberal application.]
Coverage: Don't miss spots! Cover all exposed skin, including your face, ears, neck, shoulders, hands, and feet. [This is specifically mentioned in the provided reference material.]
Reapplication: Reapply every two hours, or more frequently if swimming or sweating. [Multiple sources emphasize the importance of regular reapplication, about every two hours.] Water-resistant sunscreen provides longer protection, but still requires reapplication.

Consistency: Make sunscreen a daily habit, especially during peak sun hours (10 a.m. to 4 p.m.).
Other Protections: Sunscreen is part of a comprehensive sun protection strategy. Seek shade, wear protective clothing, and consider a wide-brimmed hat and sunglasses.
