Detailed answer

To prevent hyperpigmentation during hiking or outdoor activities, it is crucial to apply sunscreen with broad-spectrum protection and a high SPF. Choose a sunscreen that shields against both UVA and UVB rays. Apply the sunscreen generously to all exposed areas of the skin, including the face, neck, arms, and legs. Reapply the sunscreen every two hours or more frequently if you sweat excessively or come into contact with water. Additionally, consider wearing protective clothing like wide-brimmed hats, long-sleeved shirts, and pants to minimize direct sun exposure to the skin. Seek shade whenever possible, especially during peak sun hours between 10 am and 4 pm. These precautions will help reduce the risk of hyperpigmentation caused by sun damage during outdoor activities.
