Definition of Collagen and Retinol
Collagen is a protein found in the connective tissues of animals, including humans. It is the most abundant protein in the body, making up about 25-35% of total protein. Collagen fibers provide strength and support to various structures in the body, including skin, tendons, ligaments, and bones. It also plays a role in wound healing. Collagen is found in many dietary supplements and beauty products, as it is thought to improve skin health and reduce the appearance of wrinkles.
Retinol is a form of vitamin A, an essential nutrient that plays a role in many bodily functions, including vision, immune function, and cell growth and differentiation. Retinol is found in animal-derived foods, such as liver, egg yolks, and dairy products, and can also be taken as a dietary supplement. In skincare products, retinol is used as an anti-aging ingredient and is known for its ability to boost collagen production and improve the appearance of fine lines, wrinkles, and uneven skin tone.
It can also help to unclog pores and reduce the appearance of acne. Retinol is a popular ingredient in various skincare products, including creams, serums and moisturizers.
