Collagen the secret to youthful looking skin. Collagen may be the most important element of human skin. This complex protein makes up nearly 80% of skin and provides structure, elasticity and protection, while helping to retain moisture within the deep dermal layers. As aging occurs, collagen naturally decreases over time. Sooner or later, the reduction of collagen causes skin to become thinner drier and more fragile. Loss of collagen is believed to be the primary cause of fine lines and wrinkles that occur in naturally-aged skin. This truly unique and innovative product is specially designed to fight the effects of aging. Each great-tasting liquid-tube delivers superior levels of collagen, plus a broad spectrum of antioxidants and nutrients such as biotin and silica, to help revitalize the skin from the inside out. Simply mix one concentrated liquid-tube into 16oz of water per day.
