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 the immune response and can influence the overall health of the skin. Variations in the number and activity of pigment cells can lead to different skin tones and conditions, such as vitiligo or albinism.
