Peptide Comparison

Argireline vs Rigin

Q: What is the difference between Argireline and Rigin?

Argireline: Inhibits SNARE complex formation in facial muscles; reduces acetylcholine release locally; relaxes expression lines without systemic effects Rigin: Palmitoylated tetrapeptide mimicking IgG C-terminal sequence; reduces IL-6 production in keratinocytes; combined with Matrixyl (Pal-GHK) forms Matrixyl 3000; anti-inflammatory and skin matrix support

Both are Skin & Cosmetic peptides.
