As the most abundant protein in the human body, collagen serves as a structural foundation for skin, connective tissues, muscles, and blood vessels. It plays a major role in maintaining firmness, elasticity, hydration, and overall skin integrity. For decades, scientists and medical researchers have studied how collagen changes with age and how these changes contribute to visible signs of aging. Fine lines, wrinkles, sagging skin, and loss of elasticity are all closely linked to declining collagen production. As people increasingly seek effective and minimally invasive anti-aging solutions, collagen research has emerged as one of the most promising areas in modern aesthetic medicine.
