A common problem with sunscreen is that people don’t apply it enough. You should completely cover your body, including your ears, scalp, feet, and neck, and you should apply plenty of sunscreen even on cloudy days, because the sun’s UV rays can penetrate the clouds, va Hackensack Meridian Health explained in a press release.
After applying sunscreen, you should still use other types of protection, such as wide-brimmed hats and UV-blocking sunglasses.
Normally, sunscreen should be reapplied every two hours, especially if you’ve been swimming or sweating.
It is also important to check the expiration date of the sunscreen. Most sunscreens are designed to maintain their original level of protection for up to three years. If you have a sunscreen that has expired or is more than three years old, throw it away.
Sunscreens that have been exposed to high temperatures or that show obvious changes in color or consistency should also be discarded, the group said.
