Peptides for skin: GHK-Cu, Argireline and pigmentation research
Niche molecules for specific areas.
Peptides for skin covers molecules studied in dermatological research: the copper peptide GHK-Cu in collagen synthesis and skin repair, Argireline and SNAP-8 in expression-wrinkle models, and Melanotan 2 in melanocortin pigmentation pathways. At Molequa® these are strictly reference substances for laboratory research, not finished cosmetics.

Research context
This category covers niche molecules that act on specialised receptor systems. PT-141 (bremelanotide) and Melanotan 2 are studied as melanocortin-receptor agonists in research on pigmentation and central signalling, while GHK-Cu is examined for skin and pigmentation biology. These are among the most receptor-specific peptides in the catalogue. Reference material for laboratory research only.
FAQ
What are peptides in skincare?
In cosmetic research, peptides are short amino acid chains studied for their signalling role in the skin: GHK-Cu around collagen and elastin synthesis, Argireline and SNAP-8 around expression wrinkles. Our products are raw reference substances for formulation research, not ready-to-use cosmetics.
What is GHK-Cu?
GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine bound to a copper ion. It occurs naturally in blood plasma and its level declines with age. Research examines its role in collagen synthesis, elastin and skin repair processes.
How does Argireline differ from botulinum toxin?
Botulinum toxin is an injected bacterial neurotoxin blocking acetylcholine release at the neuromuscular junction. Argireline is a short synthetic peptide studied at a different point of the pathway and applied topically. Potency, mechanism and regulatory status are fundamentally different.
How do I verify quality before buying?
The batch certificate of analysis is available on the product page before purchase, listing HPLC purity, LC-MS identity, lot number and analysis date from the independent laboratory Janoshik Analytical.
