Detailed answer

To protect your skin from dark spots while on vacation, it is crucial to follow three key steps. Firstly, apply sunscreen with a high SPF (at least SPF 30) generously and reapply every two hours, especially after swimming or sweating. Secondly, seek shade during peak sun hours, typically between 10 am and 4 pm, when the sun's rays are the strongest. Lastly, wear protective clothing, such as wide-brimmed hats, sunglasses, and lightweight long-sleeved shirts, to shield your skin from direct sunlight. By diligently practicing these measures, you can significantly reduce the risk of developing dark spots and maintain a healthy complexion throughout your vacation.
