Which vitamin deficiency commonly impacts skin health?

Vitamin A plays a crucial role in maintaining skin health due to its involvement in cellular turnover, repair, and maintenance of the skin's structure. This vitamin helps to prevent dry, flaky skin and contributes to the production of sebum, which keeps the skin hydrated and protected. A deficiency in Vitamin A can lead to various skin issues, including dryness, roughness, and an increased susceptibility to infections. Additionally, Vitamin A is essential for the growth and repair of skin tissues, making it vital for overall skin vitality and resilience.

While other vitamins, like Vitamin C and Vitamin D, also contribute to skin health—primarily through collagen formation and protection against UV damage, respectively—Vitamin A is especially noteworthy for its direct impact on skin cell function and texture.
