GHK-Cu is skincare's most studied copper peptide. Research shows it activates over 4,000 genes to rebuild collagen, suppress inflammation, and reset aging skin.
Inside acetyl hexapeptide-8, the peptide behind Argireline. How it targets the SNARE complex to reduce expression lines, what the clinical data shows, and why delivery matters.
Snap-8 competes with SNAP-25 in the SNARE complex to reduce muscle contractions. Clinical data from microneedle studies shows measurable wrinkle reduction without paralysis.
Matrixyl signals skin fibroblasts to produce new collagen by mimicking a fragment of type I procollagen. Here is the full science behind palmitoyl pentapeptide-4.
