Yesterday I went over my face at 1.5 mm and layered in the polynucleotide, hyaluronic acid, and human exosomes one at a time. A few hours afterward I put on the copper peptide product, and even though I had already used the other peptides the area stayed pink and felt sensitive. I rinsed everything away after six hours and woke up with normal color. Nothing looked harmed, though the open skin clearly reacted to that last step, yet overall the surface still seems fine so maybe the earlier layers got through anyway. The polynucleotide spots I injected at both 1.5 and 2 mm depths also settled without any leftover pinkness, puffiness, or bumps. While I was reading around, what bad experiences turned up for you? I came across a note that the copper version can leave some faces looking duller and tighter.
I had everything ready to begin applying GHK topically when I fell into a deep dive on Reddit and encountered reports of it causing actual damage to skin. It would be great to get input from the community of folks who've already tried it out, like details on what succeeded or failed, the dosages used, and how they combined it with their regular creams and such.
