Collagen is the most abundant protein in the body and helps give structure to your skin, hair, and nails. As you get older, your body’s natural ability to produce collagen will decrease over time – leading to visible signs of aging.* Youtheory® Collagen Liquid is formulated with a clinical dose of collagen to help reduce the appearance of fine lines and wrinkles, increase skin elasticity, and improve the overall appearance of skin, providing a more youthful appearance. *
