Where is melanin found in the human body?

Melanin is primarily found in the epidermis, which is the outermost layer of the skin. It is produced by specialized cells known as melanocytes that are located in this layer. Melanin is responsible for the pigmentation of the skin, hair, and eyes, providing protection against the harmful effects of ultraviolet (UV) radiation by absorbing it. This function is crucial for preventing DNA damage that can lead to skin cancer and other skin-related conditions.

While melanin can also be present in hair follicles, specifically in the hair itself, its main reservoir and the area where it is most abundantly produced is within the epidermis. The dermis and hypodermis do not primarily contain melanin; instead, these layers are involved in structural support and connective tissue functions. Thus, the epidermis is the correct answer, highlighting the role of melanin in determining skin color and providing protective functions.
