Vitamins A and E help protect the outside of skin cells. What is the function of water-soluble vitamins B and C?

Water-soluble vitamins B and C play crucial roles in maintaining the health and function of the skin at a cellular level. Specifically, vitamin C is known for its antioxidant properties and its role in collagen synthesis, which is essential for skin structure and integrity. It also helps protect cells from oxidative stress by neutralizing free radicals, thus contributing to overall skin health. Vitamin B, particularly Biotin (B7), is vital for the metabolism of fats, proteins, and carbohydrates that are essential for various bodily functions, including those that support healthy skin and cell function.

While water-soluble vitamins do contribute to enhancing hydration indirectly through their metabolic functions and potential improvements in skin barrier function, their primary role is to protect and maintain the integrity of the inside of the cells. This includes aiding in cell repair, regeneration, and overall cellular health, which is foundational for healthy skin.
