Vitamin A is widely used in the healthcare and cosmetics industries due to its essential role in maintaining vision, immune function, and skin health. In medicine, it is crucial for treating vitamin A deficiency, which can lead to night blindness and other vision-related issues. It is also used in skincare products to promote cell turnover, reduce acne, and improve skin texture by stimulating collagen production. Additionally, vitamin A is incorporated into dietary supplements to support overall health and boost the immune system. Its antioxidant properties further make it valuable in combating oxidative stress and supporting healthy aging.
