Peptide Question

This question has more to do with cosmetics so, it may not really belong here but, I figure there are many knowledgeable posters who may have some insight.

I have been working in a dermatologist office for a while now in office I have seen laser treatments, derma-rolling, excisions, and TCA cross done for either acne scarring, wrinkles, or collagen production. After reading up on TB-500 I was wondering if certain peptides would aid in recovery (healing times and therefore potential scarring) and also give better overall results.

The peptides I was wondering about are:

TB-500
GHK
Biopeptide EL
Matrixyl
