Detailed answer

Hyperpigmentation is a condition characterized by the darkening of patches of skin. It is typically caused by an overproduction of melanin, the pigment that gives color to the skin. Sunscreen, on the other hand, is formulated to protect the skin from the harmful effects of the sun's ultraviolet (UV) rays. It helps to prevent sunburn, skin damage, and the development of skin cancer. Regular and consistent use of sunscreen is actually beneficial in preventing hyperpigmentation. However, it is important to note that some people may experience a condition called post-inflammatory hyperpigmentation, which can occur as a result of skin inflammation or injury, including sunburn. In such cases, it is not the sunscreen itself that causes hyperpigmentation, but rather the underlying skin damage or inflammation. To minimize the risk of post-inflammatory hyperpigmentation, it is crucial to use broad-spectrum sunscreen with a high SPF, seek shade during peak sun hours, and wear protective clothing.
