Detailed answer

To prevent hyperpigmentation during outdoor gardening or yard work, it is important to follow these steps:

1. Apply a broad-spectrum sunscreen with a minimum SPF of 30 to all exposed areas of the skin. Reapply every two hours or more frequently if sweating excessively.

2. Wear protective clothing such as wide-brimmed hats, long-sleeved shirts, and long pants to minimize direct sun exposure.

3. Limit your time outdoors during peak sun hours, typically between 10 am and 4 pm, as the sun's rays are strongest during this time.

4. Seek shade whenever possible, especially if you are spending extended periods outdoors.

5. Consider using a physical barrier, such as an umbrella or canopy, to create additional shade and protection.

By following these preventive measures, you can reduce the risk of hyperpigmentation and maintain healthier, more even-toned skin.
