No, collagen from animal sources, of course, would be broken down into its consistutents, proline and lysine. If any were not to be broken down, it certainly would not magically migrate to the skin.

There certainly are ways you can boost collagen production orally such as Vitamin C which the above amino acids need to produce procollagen. Thus there are ways to help with collagen production. But to eat collagen, it would not work.

Thank you for your interesting question.
