Question

Which is best applying protien topigrafically, or internally?

Answer 1

If the protein is related to the skin, related to loss of collagen or elastin, then peptide to the skin can make you look younger.

Some products can be injected to make the skin look younger..collagen injections, etc.

Protein is the building block of the body and processes many basic functions of the body.  I would assume that protein taken internally at the right amount would be more beneficial.See links below.

Answer 2

For what purpose?

Protein must be digested. To do so it must pass through the digestive system.
