Which vitamin aids in accelerating the skin's healing process and boosts the immune system?

Vitamin C is essential for skin health, particularly in its role in healing and immune system support. This vitamin is a powerful antioxidant that helps to protect skin cells from damaging free radicals and oxidative stress. It is critical in collagen synthesis, which is a vital protein that aids in the healing of wounds and supports the overall structure of the skin. By stimulating collagen production, vitamin C helps improve skin texture and promote faster healing of injuries or blemishes.

Moreover, vitamin C plays a significant role in enhancing the immune response. It helps stimulate various cellular functions of both the innate and adaptive immune systems. By increasing the production of white blood cells and antibodies, it fortifies the body’s defense mechanisms against infections and diseases, further contributing to healthier skin.

While the other vitamins mentioned have their benefits—such as vitamin A promoting skin cell turnover, vitamin B aiding in energy production and skin barrier function, and vitamin D being important for skin development and immunity—they do not have the same pronounced effects on the skin's healing process and immune boosting as vitamin C does.
