Applying sunscreen correctly is crucial for effective sun protection. Here's how to do it:
When to Apply Sunscreen
- Before Sun Exposure: Apply your first coat 15-20 minutes before going outdoors to allow it to absorb into your skin. (Source: NYTimes Wirecutter)
- Reapplication: Reapply at least every two hours, or more frequently if swimming or sweating. (Source: FDA, MD Anderson Cancer Center) Follow the manufacturer's instructions for specific reapplication guidelines.
Where to Apply Sunscreen
Apply sunscreen liberally to all exposed skin. This includes:
- Face: Don't forget your ears and the back of your neck.
- Neck & Ears: These areas are often missed.
- Head: Especially important if you have thinning or no hair. A wide-brimmed hat offers additional protection. (Source: Reference 1)
- Body: Arms, legs, hands, and feet should all be covered. Pay attention to hard-to-reach areas like your back. (Source: AAD)
How Much Sunscreen to Use
Use enough sunscreen to generously cover all exposed skin. A common guideline is about one ounce (a shot glass full) for your entire body.

- Different Sunscreen Types:
- Lotions and Creams: Apply with your fingertips and blend well.
- Sprays: Hold the can 6-8 inches away from your skin and spray evenly. Make sure to thoroughly rub it in to ensure complete coverage.
- Powders: Apply using the provided applicator (brush or puff) (Source: Supergoop!, Jane Iredale).
Choosing the Right Sunscreen
- SPF Value: Opt for a broad-spectrum sunscreen with an SPF of 15 or higher. (Source: FDA) Higher SPFs offer greater protection. The NHS recommends at least SPF 30 with 4-star UVA protection. (Source: NHS)
- Broad Spectrum: This protects against both UVA and UVB rays.
Remember: Sunscreen is a crucial part of your sun protection strategy. Combine it with protective clothing, shade, and limiting your time in the sun for optimal results.
