Which Vitamin is important for maintaining the skin's tone and elasticity?

• A. Vitamin C
• B. Vitamin E
• C. Vitamin A
• D. Vitamin K

Answer: (A)

Collagen provides the framework that keeps skin firm, smooth, and resilient, so keeping collagen healthy is key to skin tone and elasticity. Vitamin C is essential here because it acts as a critical cofactor for the enzymes that hydroxylate collagen molecules, allowing strong and stable collagen fibers to form. It also helps protect collagen from oxidative damage as an antioxidant, preserving skin structure over time. While other vitamins support skin in various ways—such as vitamin A promoting normal cell turnover and vitamin E protecting cell membranes—their roles aren’t as directly tied to collagen production and the resulting elasticity. Vitamin K isn’t a major player in elasticity either. So vitamin C best supports tone and elasticity through collagen synthesis and antioxidant protection.
