The best SPF is broad-spectrum SPF 30 or higher. This recommendation comes from the American Academy of Dermatology (AAD), and it's important to follow this guideline to protect your skin from harmful UV rays.
While SPF 50 might sound like a better option, the difference in protection between SPF 30 and SPF 50 is minimal. SPF 30 blocks 97% of UVB rays, while SPF 50 blocks 98% of UVB rays.
Here are a few important factors to consider when choosing an SPF:
- Broad Spectrum Protection: Ensure your sunscreen protects against both UVA and UVB rays. UVA rays cause premature aging, while UVB rays cause sunburn.
- Water Resistance: If you're spending time in the water, choose a water-resistant sunscreen.
- Application: Apply sunscreen liberally and reapply every two hours, or more often if you're sweating or swimming.
Remember: Sunscreen is an essential part of protecting your skin from sun damage, but it's not the only protection you need. Also, use protective clothing, hats, and sunglasses when you're outdoors.
