Which vitamin is known to aid in skin healing and repair?

Vitamin A plays a crucial role in skin healing and repair due to its involvement in various biological processes that promote healthy skin function. This vitamin is essential for skin cell production and regeneration, which is vital for effective wound healing. It helps maintain the integrity of the skin by supporting the formation of new skin cells and promoting the development of collagen, a protein that is a key component of skin structure. Additionally, vitamin A has antioxidant properties that help protect skin from damage caused by free radicals and environmental stressors.

While other vitamins listed, such as Vitamin C, have important roles in skin health—especially in collagen synthesis and antioxidant protection—Vitamin A is particularly significant for the complete cycle of skin repair. Vitamin D is important for immune function and overall skin health, while Vitamin E acts as an antioxidant, but does not have the same direct impact on skin healing as Vitamin A.
