Vitamin C
Vitamin C is a naturally occurring nutrient found in many fruits and vegetables, especially citrus fruits, berries, and leafy greens, and it has been recognized as an essential vitamin since its identification in the early 20th century. Historically, plants rich in vitamin C were valued in traditional diets around the world, and scientific research later led to the development of stable vitamin C ingredients for food and personal care applications. Today, vitamin C is widely used in all-natural skin care products, serums, lotions, and creams, where it is appreciated as a plant-derived nutrient and valuable ingredient in modern botanical formulations.
