Detailed explanation-1: -Freckles and moles are seen where melanin is concentrated in one spot. Melanin ranges in color from yellow to brown to black. More melanin is produced when the skin is not exposed to sunlight. The stratum basale cells phagocytize the melanin produced by the melanocytes and it accumulates within them.
Detailed explanation-2: -Freckles are the result of an overproduction of melanin. Melanin is a pigment that gives your hair, skin and eyes (your “complexion”) its color. Melanin, produced by skin cells called melanocytes, protects your skin from sun damage by absorbing and reflecting ultraviolet light (UV).
Detailed explanation-3: -Melanocytes produce melanin, a pigment that provides skin with its color. When the melanocytes clump together, they continue producing melanin, resulting in a higher concentration of melanin in that area. This concentration of melanin is what gives a mole its darker color.
