A  client asked me about this new "active" to plump lips.

Sepilift DPHP is announed as a "French botanical" (whatever that may be, but is really Dipalmitoylhydroxy Proline. This modified amino acid is useless because hydroxyproline is an amino acid that cannot be used to make proteins. It is true that hydroxyproline is an amino acid in collagen, but the hydroxylation happens after protein synthesis not before, so the amino acidactually used in collagen synthesis is proline, NOT hydroxyproline.
