Collagen is crucial in maintaining the structural integrity of various tissues in the human body, and its decrease contributes markedly to the aging process. A recent study found that supplemental collagen combined with antioxidants substantially improved the appearance and health of skin and hair in adult women, reducing wrinkle depth by 48 percent.

The study involved 40 healthy adult women between the ages of 38 and 50. Participants consumed a commercially available collagen treatment containing collagen, hyaluronic acid, biotin, and vitamins C and E or a placebo for 56 days. Researchers evaluated various aspects of their skin, such as elasticity, hydration, brightness, and pigmentation, along with hair strength and hair fall (normal hair loss) before, during, and after the intervention.

They found that those who consumed the collagen treatment experienced a 48 percent reduction in wrinkle depth, a 39 percent reduction in fine lines, and a 16 percent increase in skin hydration compared to those who took a placebo. Their hair fall decreased by 28 percent versus 7 percent among those who took a placebo.

The findings from this small study suggest that supplemental collagen and antioxidants improve skin and hair health. Collagens are characterized by a triple helix arrangement, forming a sturdy, resilient structure. They serve general tissue assembly and maintenance functions, including tissue scaffolding, morphogenesis, and repair. Learn more about collagen in our overview article.
