SPF50+ sunscreens that are water-resistant for 80 minutes offer several benefits:

1. High Sun Protection: SPF50+ sunscreens provide a high level of protection against harmful UVB rays. They allow only about 2% of UVB rays to reach your skin.
2. Broad Spectrum Protection: These sunscreens also offer broad-spectrum protection, which means they protect against both UVA and UVB rays.
3. Water Resistance: Being water-resistant for 80 minutes, these sunscreens continue to provide sun protection even when you’re swimming or sweating. However, it’s important to reapply the sunscreen every 80 minutes while swimming or immediately after towel drying.
4. Prevents Sun Damage: These sunscreens help prevent prolonged skin damage from UV light and environmental assault.
5. Moisture Retention: Some SPF50+ sunscreens contain oleosome microspheres that enhance SPF performance and counteract moisture loss triggered by extended daylight exposure.
6. Suitable for Outdoor Activities: The Skin Cancer Foundation recommends a water-resistant, broad-spectrum sunscreen with an SPF of 30 or higher for any extended outdoor activity. An SPF50+ sunscreen exceeds this recommendation, making it suitable for long durations of outdoor activities.

Remember, no matter how high the SPF, it’s important to apply sunscreen liberally and evenly to skin, preferably 15 minutes prior to sun exposure, and reapply it every two hours or immediately after swimming and sweating.
