Detailed answer

To prevent hyperpigmentation during outdoor concerts or music festivals, it is important to take proper sun protection measures. Apply a broad-spectrum sunscreen with at least SPF 30 to all exposed areas of the skin, including the face, neck, arms, and legs. Reapply every two hours and after sweating or swimming. Seek shade whenever possible, especially during the peak sun hours of 10 am to 4 pm. Additionally, consider wearing protective clothing such as wide-brimmed hats, long-sleeved shirts, and pants to minimize sun exposure. Remember to stay hydrated and take regular breaks from the sun to reduce the risk of hyperpigmentation.
