Vitamin A is widely used in the healthcare and cosmetic industries. In healthcare, it is essential for maintaining good vision, supporting immune function, and promoting healthy skin. It is often included in dietary supplements to address deficiencies and improve overall health. In dermatology, Vitamin A derivatives, such as retinol, are used in treatments for acne, psoriasis, and other skin conditions due to their ability to promote cell turnover and reduce inflammation. In the cosmetic industry, it is a key ingredient in anti-aging products, helping to reduce wrinkles and improve skin texture by stimulating collagen production. Additionally, Vitamin A is used in food fortification programs to combat malnutrition, particularly in regions where deficiencies are prevalent.
