Eating pig's trotters can beautify the face.

Argument basis: trotters are rich in collagen, which is good for the skin and can be used for beauty.

The rumor is shattered: after eating collagen, it needs to be digested and decomposed into amino acids or "peptides" to be absorbed into the blood, and the absorbed amino acids need to be recombined to form the protein needed by the human body, and will not directly appear on the face in the form of collagen.
