Melanocytes are found in the epidermis, mixed amongst the rest of your skin cells, known as keratinocytes. When a melanocyte gets exposed to UV rays (ie the sun) it secretes melanin, and puts it into little packages (vesicles) called melanosomes. It delivers the melanosomes to the surrounding keratinocytes, which break them open with lysosomes to release the melanin into their cytoplasm. The melanin then goes to surround the nucleus of the cells, and protect its DNA from any more UV light.
If you look at cells with lots of melanin vs. cells with little melanin under a microscope, you will notice that the cells with lots of melanin have very dark nuclei.
