What causes dark skin pigmentation and how is it influenced by factors such as genetics, sun exposure, and ethnicity?
Dark skin pigmentation is primarily caused by the presence of melanin, a pigment produced by specialized cells called melanocytes in the skin. Genetics play a significant role in determining the amount and type of melanin produced, which in turn affects skin color. Sun exposure can stimulate melanin production, leading to tanning, while certain ethnicities have naturally higher levels of melanin, resulting in darker skin tones.
