Does sunscreen need to be reapplied after swimming or sweating?
Short answer: Yes, sunscreen should be reapplied after swimming or sweating.
Detailed answer
Yes, sunscreen needs to be reapplied after swimming or sweating as it can easily be removed or diluted by water or sweat. Water-resistant sunscreens are designed to stay on the skin for a certain amount of time while swimming or sweating, but they will still need to be reapplied after towel-drying or significant water exposure. It is essential to follow the instructions on the sunscreen packaging to know how often it should be reapplied. Generally, it is recommended to reapply sunscreen every two hours or more frequently if you are sweating heavily. Reapplying sunscreen ensures continuous protection against harmful UV rays and helps to maintain its effectiveness throughout the day.
