Detailed answer

Hyperpigmentation, which refers to dark patches on the skin, can be influenced by climate. Excessive sun exposure, common in hot and sunny climates, can stimulate the production of melanin, resulting in hyperpigmentation. High humidity and heat can also lead to increased sweating, which can clog pores and trigger acne breakouts, thereby causing post-inflammatory hyperpigmentation. Conversely, cold and dry climates can lead to dry and flaky skin, which can exacerbate the appearance of hyperpigmentation. Therefore, it is important to protect the skin from the sun, maintain proper hydration, and use appropriate skincare products in accordance with the specific climate to minimize hyperpigmentation.
