Melanocytes produce melanin. These specialized cells are found in the basal layer of the epidermis, the outermost layer of skin. Melanocytes create melanin through a process called melanogenesis, which is stimulated by ultraviolet (UV) radiation. Melanin is then transferred to keratinocytes, which carry it to the skin surface. The amount of melanin produced determines the color of our skin, hair, and eyes.
Here are some additional facts about melanin production:
- Genetics: The amount of melanin your body produces is largely determined by your genes.
- UV exposure: Sun exposure triggers melanocytes to produce more melanin, leading to a tan. This is a protective mechanism against UV damage.
- Other factors: Hormonal changes, certain medications, and some medical conditions can also affect melanin production.
