GHK-Cu + Snap-8 Serum is a pre-formulated cosmetic research serum combining two mechanistically distinct peptides. GHK-Cu (Gly-His-Lys·Cu²⁺; CAS 49557-75-7) is a naturally occurring copper tripeptide complex studied for extracellular matrix remodelling, collagen and elastin synthesis, and skin regeneration signalling. Snap-8 (Acetyl Octapeptide-3; CAS 868844-74-0) is a SNARE complex inhibitor studied for its ability to attenuate acetylcholine-mediated muscle contraction at the neuromuscular junction.

Together they address two primary mechanisms in skin aging biology: structural matrix degradation (addressed by GHK-Cu's ECM upregulation) and dynamic expression line formation (addressed by Snap-8's SNARE inhibition). This combination is commonly studied in cosmetic peptide research as a model for multi-mechanism topical formulations.
