Skin Color Skin Color Biological Factors Environmental Factors - Skin color is unique to everyone. The color is due to the density of melanin. - It is important to know that the number of melanocytes does not vary significantly from one person to the next, but what does vary is the density of the melanin produced. - It is fairly difficult to determine who has the exact same skin “color,” just by looking. Unless the person has a microscopic eye that can also calculate the density of the melanin, this task is pretty much impossible. The skin has a couple layers: - The dermis is considered the “inside” layer. This is where blood vessels, glands, hair follicles are located. - The dermis does not play a large role in the determination of skin color. - Epidermis, or the “outside” layer includes cells that continuously divide and replace themselves pushing toward the top. - ^ this would be called skin. - In between the Epidermis and Dermis is a layer of cells called the melanocytes. - Melanocytes are what produces melanin and distributes it to other cells in the epidermis. -
