Which vitamin is associated with collagen production and improved skin texture?

• A. Vitamin A
• B. Vitamin B
• C. Vitamin C
• D. Vitamin D

Answer: (C)

Vitamin C is essential for collagen production and skin texture. It acts as a cofactor for the enzymes that hydroxylate proline and lysine in collagen, a step needed to form the stable triple-helix structure of collagen fibers. This proper structure allows collagen to assemble into a strong extracellular matrix, which gives skin its firmness and smooth texture. Vitamin C also helps regenerate the enzyme cofactors and provides antioxidant protection, supporting ongoing collagen synthesis and repair. Without adequate vitamin C, collagen fibers are weak, leading to poorer skin texture and slower healing. While other vitamins support skin health in different ways, the direct link to collagen formation and improved texture is due to vitamin C.
