While Nivea sells sunscreens labeled "water-resistant" or " long-lasting," it's important to remember that no sunscreen can provide all-day protection.
The effectiveness of sunscreen decreases with sweat and water exposure. Even if a sunscreen is labeled "water-resistant," it should still be reapplied after swimming, heavy sweating, or toweling off. Furthermore, sunscreens lose effectiveness over time due to UV ray exposure, so reapplying every two hours, or more frequently if swimming or sweating, is essential for adequate protection.
Nivea's "water-resistant" or "long-lasting" sunscreens may protect for up to 80 minutes of swimming or sweating, according to their advertising. However, it is still recommended that you reapply after this timeframe, or sooner if necessary, to ensure continued protection from harmful UV rays. As a result, while Nivea sunscreens provide long-lasting protection, regular reapplication is required to ensure effective sun protection throughout the day.
