Vitamin A
Vitamin A is a naturally occurring nutrient found in plant sources such as carrots, sweet potatoes, and leafy greens, as well as in animal-derived foods, and has been recognized as an essential vitamin since its discovery in the early 20th century. Historically, cultures around the world valued vitamin A-rich foods for their nutritional importance, while scientific research later led to the development of vitamin A derivatives for use in personal care formulations. Today, vitamin A is used in all-natural skin care products, creams, serums, and botanical formulations, where it is appreciated as a naturally occurring nutrient and valued ingredient in modern cosmetic products.
