Water-resistant sunscreens are designed to maintain their SPF amount for a predetermined amount of time while exposed to water or sweat, but they still need to be reapplied after swimming or exaggerating the sweat.

This keeps sunscreen protected while maintaining adequate protection because it can eventually fade as a result of exposure to sunlight, sweat, and other elements.
After Swimming or Sweating: Even when using a water- resistant sunscreen, reapply immediately after swimming, sweating heavily, or towel- drying. Depending on the particular product and its instructions, water-resistant sunscreens will remain effective for 40 to 80 minutes in water.
Under Makeup: If you wear makeup, you might want to use a sunscreen contact-up product or an SPF-containing setting spray to keep your makeup safe all day long without stumbling upon it.
Apply sunscreen even on cloudy days to properly protect your skin: UV rays can pierce through clouds.
Particular Activities: If engaging in activities that increase sun exposure ( e. g., hiking, skiing ), reapply sunscreen more regularly, ideally each 1- 1.5 hours.
