Collagen: An Overview from Past to Future Applications

Abstract
Collagen, a structural protein, prevalent in animals, especially in skin, bones, and joints, responsible for providing fundamental structural support, is being used extensively in cosmetics. Mammalian and fish skin are the most common sources of collagen. Collagen's unique qualities, such as its role as a natural humectant and moisturizer for the skin, have piqued the curiosity of both academics and the cosmetic industry. In this review study, collagen biosynthesis, collagen sources used in the cosmetic industry, and collagen's function in cosmetics are discussed along with future aspects of collagen-based materials in cosmetics.
