In what manner should sunscreen be applied for best results?

• A. Only on sunny days
• B. As a final step after makeup
• C. In layers for enhanced protection
• D. At least 15 minutes before sun exposure

Answer: (D)

Applying sunscreen at least 15 minutes before sun exposure is essential for optimal effectiveness. This practice allows the active ingredients in the sunscreen to absorb and form a protective barrier on the skin. Sunscreens typically take some time to interact with the skin to provide maximum protection against harmful UV rays. By applying it ahead of time, you ensure that the skin is adequately protected when exposure begins, thereby reducing the risk of sunburn and long-term skin damage. While some methods, such as applying sunscreen in layers for enhanced protection, can be beneficial in specific scenarios, they do not replace the need for the initial application time. The timing of application is crucial, especially since UV radiation levels can increase quickly during sunny and even overcast days. Therefore, allowing for this 15-minute interval is a standard recommendation by dermatologists to achieve the best protective results from sunscreen application.
