To ensure your sunscreen is effective, look for the following:
- SPF 30 or higher: The American Academy of Dermatology recommends using a sunscreen with an SPF rating of 30 or higher. This means the sunscreen will block 97% of the sun's harmful UVB rays.
- Broad Spectrum: Look for the words "broad spectrum" on the label. This indicates the sunscreen protects against both UVA and UVB rays, which are responsible for sunburn and premature aging.
- Water Resistance: If you plan to swim or sweat, choose a sunscreen labeled "water resistant." This will help it stay effective for longer.
- Expiration Date: Sunscreen does expire, so check the expiration date on the bottle. After that date, it may not be as effective in protecting your skin.
You can also consult the Environmental Working Group (EWG) sunscreen guide for additional information. The EWG provides safety ratings for sunscreens based on their ingredients and effectiveness.
Finally, remember that sunscreen is only one part of sun protection. Other important measures include seeking shade, wearing protective clothing, and limiting your time in the sun, especially during peak hours.
