Which vitamin is known for protecting the skin from free radical damage?

1. Vitamin B

2. Vitamin C

3. Vitamin A

4. Vitamin E

The correct answer is: Vitamin A

The correct choice is Vitamin E, which is known for its powerful antioxidant properties that help protect the skin from free radical damage. Free radicals are unstable molecules that can cause oxidative stress leading to premature aging, skin damage, and various skin concerns. Vitamin E neutralizes these free radicals, thereby helping to maintain skin health and preventing the deterioration of skin cells. While Vitamin C is also a potent antioxidant and contributes to skin health by supporting collagen production and reducing pigmentation, the focus here is on the specific role of Vitamin E in protecting the skin from oxidative damage. Vitamin A is crucial for skin cell production and repair, while Vitamin B encompasses a range of beneficial effects for skin moisture and texture, but does not primarily serve the antioxidant function associated with free radicals as Vitamin E does.
