While collagen is an important part of the skin and provides structural support and elasticity, which results in youthful and healthy-looking skin, after age 20, people start losing their body’s collagen supply each year. As the production of collagen breaks down, it can result in wrinkles, sagging skin, and fine lines. While some studies suggest that taking collagen supplements may enhance skin hydration and elasticity, as well as improve muscle mass, the findings from early research on the potential benefits of consuming extra collagen are too restricted to be considered definitive or broadly accepted.

Collagen supplements face a significant challenge in that they cannot selectively target specific areas of the body, and there is no guarantee that the body will recognize the ingested collagen. Once collagen is consumed, it is broken down and absorbed into the bloodstream, where it is distributed to various body parts as required. As a result, it is difficult to predict whether the consumption of collagen will have a significant impact on the body or, more specifically, the skin.
