• Skin color is determined by the amount and type of melanin pigment produced in the skin. Melanin is produced by specialized cells called melanocytes and is the primary determinant of skin color. The amount and distribution of melanin in the skin can vary greatly between individuals and populations.

• Genetics plays a crucial role in determining skin color. Multiple genes, including MC1R, TYRP1, OCA2, and KITLG, are involved in the production and regulation of melanin. Variations in these genes can lead to differences in skin pigmentation, ranging from very light to very dark skin tones.

• Environmental factors, such as exposure to ultraviolet (UV) radiation from the sun, can also influence skin color. UV radiation stimulates the production of melanin, which acts as a natural sunscreen to protect the skin. Individuals with darker skin tones generally have higher levels of melanin, which provides more protection against UV damage.
