Pigment cells, also known as melanocytes, are specialized cells found in various tissues of the body, including the skin, eyes, and hair. Their primary function is to produce pigments, such as melanin, which give color to these tissues and protect them from harmful ultraviolet (UV) radiation. In addition to providing color, pigment cells play a role in regulating the immune response and maintaining the overall health of the skin. The number and activity of pigment cells can vary among individuals, contributing to differences in skin tone and susceptibility to sun damage.
