What is the difference between peptides for wrinkles versus peptides for scars?
Mechanism overlap exists but target depth differs. Wrinkle peptides (acetyl hexapeptide-8, palmitoyl oligopeptides) often work in the upper dermis or through neurotransmitter modulation to reduce muscle contraction. Scar peptides (GHK-Cu, matrikines) target fi

- Mechanism overlap exists but target depth differs. Wrinkle peptides (acetyl hexapeptide-8, palmitoyl oligopeptides) often work in the upper dermis or through neurotransmitter modulation to reduce muscle contraction. Scar peptides (GHK-Cu, matrikines) target fibroblasts in the mid-to-deep dermis where scar tissue resides. Scar treatment requires deeper penetration and higher concentrations. Marketing often conflates these applications. A peptide serum for 'fine lines and scars' is unlikely to contain therapeutic concentrations for either indication.
