How should sunscreen be applied for effective protection during the day?

For effective protection from harmful UV rays throughout the day, sunscreen should be applied regularly rather than just once in the morning. This is crucial because sunscreen can wear off due to various factors such as sweating, swimming, and even just the passage of time throughout the day. The effectiveness of sunscreen diminishes, and reapplying ensures that the protective barrier remains intact throughout your activities.

Applying sunscreen only once in the morning could leave skin vulnerable later in the day, especially during peak sun hours. Additionally, applying it only before swimming or every few hours could lead to gaps in protection if not done consistently. Hence, continuous application throughout the day is essential for maintaining optimal skin protection from UV exposure.
