Melanin production by melanocytes influences which characteristics?

• A. Skin hydration
• B. Skin elasticity
• C. Color of skin and hair
• D. Skin thickness

Answer: (C)

Melanin is the pigment produced by melanocytes in the epidermis, and it determines how skin and hair appear. The amount and type of melanin produced regulate the shade, from light to dark skin and a range of hair colors. When melanin production increases, skin and hair darken; when it decreases, they appear lighter. Melanin mainly affects pigment, not the skin’s moisture, elasticity, or thickness. Hydration depends on water content and barrier function; elasticity and thickness depend on structural components like collagen and elastin and the layers of the skin. So the characteristic influenced by melanin production is the color of skin and hair.
