I have been using copper peptides for about 10 days and I'm already seeing results. But I'm not sure if it's from copper peptides since I have also been doing exfoliation with microdermabrasion cloth and lacsal/salicylic acid product and skin needling with thin acupuncture needles. They say that it usually takes at least one month to see results from copper peptides and exfoliation acids. They claim that with that combination most scars can be reduced or even completely removed with months or years of consistent usage. Doctors say that it's impossible, but on the other hand they use just scalpels, lasers and other very old and harsh methods
Retin A and other retinoic acids are often used in combination with copper peptides.
