Detailed answer

Hyperpigmentation refers to the darkening of patches on the skin. It is mainly caused by an overproduction of melanin, the pigment that gives color to the skin. Constant use of sunscreen or sunblock actually helps prevent hyperpigmentation by blocking harmful UV rays that stimulate melanin production. Sunscreen or sunblock with a high SPF (Sun Protection Factor) can effectively protect the skin from the sun's damaging rays and reduce the risk of hyperpigmentation. However, it is important to note that some individuals may experience post-inflammatory hyperpigmentation after sun exposure, especially if they have sensitive skin or a history of skin damage. In these cases, it is recommended to use sunscreen or sunblock regularly and seek advice from a dermatologist for appropriate treatment and prevention of hyperpigmentation.
