All the information you have posted is correct, except for the last part.
And a lot of it + extra details are all on the http://www.skinbiology.com
site, which is an excellent resource.
The skin ABSOLUTELY CAN be reprogrammed in a lot of scar problems, through the use of intensive acid peels and regeneration with proper copper peptide products. The acids slowly strip away at the layers of the skin and penetrate into the deeper areas of the tissue, overtime dissolving the lower dermis scar tissue, use of strong copper peptides speeds this up a great deal. I am living proof of this. There will be discomfort and potentially increased problems initially (as seen in the second link below) but if you stick with, problems CAN be healed. I know you've tried those products before, I just wonder how you applied them?
Ive seen such an improvement.
