Melanocytes are specialized cells located primarily in the skin, and their primary function is to produce melanin, the pigment responsible for the color of skin, hair, and eyes. This pigment serves not only as a determinant of physical appearance but also plays a crucial role in protecting the skin from the harmful effects of ultraviolet (UV) radiation. When the skin is exposed to UV light, melanocytes increase melanin production as a natural defense mechanism to reduce the risk of DNA damage that can lead to skin cancer.

The other options pertain to different functions that are not related to melanocytes. For instance, oil production is the role of sebaceous glands, while new skin cells are formed by keratinocytes. Sweat production is regulated by sweat glands. Understanding these distinct functions helps clarify the vital role of melanocytes in skin health and pigmentation.
