The duration of protection depends on which of our sunscreens you’re using: SPF 50: Our SPF 50 sunscreen provides up to 4 hours of broad-spectrum UVA/UVB protection under normal conditions. SPF 30: Our SPF 30 sunscreen offers up to 2 hours of effective sun protection. However, for both versions, we recommend reapplying after swimming, sweating, or towel-drying to maintain maximum protection. Tips for Best Results: Always apply sunscreen on dry skin for the best absorption and even coverage. Reapply every 2 hours if you are in direct sunlight or engaged in activities like swimming or exercising. By following these steps, you’ll ensure optimal protection from harmful UV rays while enjoying your time outdoors!
