What vitamin is important to skin and tissue repair?

Vitamin A
Vitamin C
Vitamin D
Vitamin E

The correct answer is: Vitamin C

Vitamin C is crucial for skin and tissue repair due to its role in collagen synthesis, a key protein that helps maintain skin structure and elasticity. This vitamin is essential for the healing process, as it aids in the formation of new skin tissues and blood vessels, promoting overall skin health and recovery from wounds. Furthermore, Vitamin C also acts as an antioxidant, helping to protect skin cells from damage caused by free radicals, thus enhancing the skin’s ability to repair itself. In relation to the other vitamins, while Vitamin A plays a role in cell growth and repair, and Vitamin E is known for its antioxidant properties that protect the skin from damage, they do not directly influence the collagen synthesis process as effectively as Vitamin C does. Vitamin D has various functions concerning bone health and immune support but is less involved in the specific processes of skin and tissue repair. Thus, the significance of Vitamin C in promoting skin and tissue health makes it the correct choice for this question.
