I thought about it, and then I decided what the person was asking was so far
from making sense that it would be best to just say "no" than to try to
correct it point by point. It's like when it's better to demolish a
structure or junk a car rather than fixing it. And I was afraid that
elaborating like this would could off as insulting. Some of the material,
quoted again below, looks as if it might be somewhat scrambled from a
previous source, maybe reversing cause & effect, maybe conflating meanings
of "communication", so I thought best that the person go back & look again
if that's the case.

Is there anyone who disagrees with my assessment? I'd just suggest studying
the structure of skin, the structure & function of collagen, and learn about
the regulation of protein synthesis & turnover in general and in this
particular case. If there are some PARTICULAR peptides being used in skin
care products, ask their purveyors what they're supposed to do. There are
various peptide hormones (insulin being a common example), some of which may
regulate the production or secretion or uptake of certain proteins, and if
there's one that does so for collagen or its precursors or collagenase
directly or indirectly I just don't know about it, nor do I know whether
they would be effective administered via any skin care product. I would
think it would have to be taken by injection or maybe nose spray.
