What is a critical vitamin that helps combat the harmful effects of the sun's rays?

  1. Vitamin A

  2. Vitamin C

  3. Vitamin D

  4. Vitamin E

The correct answer is: Vitamin E

Vitamin E is recognized as a critical vitamin that helps combat the harmful effects of the sun's rays due to its potent antioxidant properties. It plays a crucial role in protecting skin cells from oxidative damage caused by UV radiation, which can lead to premature aging and skin cancer. By neutralizing free radicals generated from sun exposure, Vitamin E contributes to maintaining the integrity of skin health and resilience against environmental stressors. Furthermore, Vitamin E can enhance the effectiveness of other antioxidants, such as Vitamin C, providing a synergistic effect that further protects the skin. While other vitamins also play important roles in skin health and protection, Vitamin E is particularly noted for its specific function in mitigating the adverse effects of sun exposure.
