Causes Of Skin Pigmentation: Skin pigmentation can be influenced by various factors. One primary cause is melanin, the pigment responsible for skin color. Genetics play a significant role, as individuals inherit their melanin production capabilities from their parents. Sun exposure is another key factor; UV rays stimulate melanin production as a protective mechanism. Hormonal changes during pregnancy or from birth control pills can also lead to pigmentation changes, known as melasma. Skin trauma or inflammation, like acne or wounds, can trigger post-inflammatory hyperpigmentation. Furthermore, age-related pigmentation changes, such as age spots, are common. Understanding these causes is essential for effective pigmentation management and prevention.
