What does pentapeptide -4 do?

Hi Right Brain-
I'd actually asked a question before about peptides in general and if they boost collagen production or if that was just marketing. Anyway I wondered if you were able to locate any studies that support that. On a similar note, what does the pentapeptide-4 do - if anything? It's in Olay Regenerist products and probably some other moisturizers have something similar called Matrixyl I think. Thanks very much

Regarding Matrixyl, read this: http://www.smartskincare.com/treatments/topical/pentapeptide.html

The bottom line is that (like so many other ingredients) there's data from lab tests on skin cells that show it increases collagen production but there's little clinical data from testing on real skin. And the testing that has been done on skin is from the people selling this product so there's the chance of bias.

I love how the booby brains never get pissy if you ask something they have already covered.

Ha you said "booby."
