Collagen is a protein that is found abundantly in the human body, specifically in the skin, tendons, ligaments, and bones. Its history dates back to ancient times when it was used for longevity purposes in China and Greece. However, it was not until the mid-20th century that collagen began to be studied and used in a more modern health approach. Today, it is widely used in the cosmetic industry to help combat the appearance of wrinkles and promote skin elasticity. Collagen supplements have also gained popularity in recent years for their potential health benefits, such as supporting joint health and providing powerful antioxidant properties for the hair, skin, and nails.
