Melitane (Acetyl Hexapeptide-1)
Overview
Acetyl Hexapeptide-1 is a synthetic hexapeptide designed to stimulate melanin synthesis by acting as an agonist at melanocortin-1 receptors on melanocytes. The acetyl modification is intended to improve peptide stability and cellular permeability. Its therapeutic rationale is to promote tanning and photoprotection through increased melanogenesis, potentially offering a biomimetic alternative to UV exposure for pigmentation enhancement.
Key Research Findings
In vitro studies have shown increased tyrosinase activity and melanin content in melanocyte cultures. Small-scale human studies have reported modest increases in skin pigmentation without UV exposure, though safety data regarding long-term use and effects on melanocytic proliferation are limited.

Afamelanotide (Scenesse)
FDA ApprovedA synthetic 13-amino acid analog of alpha-melanocyte-stimulating hormone (alpha-MSH) with a substitution of norleucine at position 4 that confers enhanced potency and enzymatic stability. Afamelanotide activates melanocortin-1 receptors (MC1R) on melanocytes, stimulating eumelanin production independent of UV exposure. The resulting increase in skin eumelanin provides photoprotection by absorbing UV radiation and scavenging reactive oxygen species.
Argireline (Acetyl Hexapeptide-8)
InvestigationalArgireline is a synthetic six amino acid peptide (Ac-Glu-Glu-Met-Gln-Arg-Arg-NH2) designed to attenuate neurotransmitter release at the neuromuscular junction. It functions as a competitive inhibitor of the SNARE complex, reducing catecholamine release and potentially diminishing muscle contraction intensity in facial expression muscles. This mechanism provides a topical alternative rationale to botulinum toxin for addressing expression lines, though with markedly lower potency.
Matrixyl (Palmitoyl Pentapeptide-4)
InvestigationalMatrixyl is a lipopeptide composed of a pentapeptide sequence (Lys-Thr-Thr-Lys-Ser) attached to a palmitic acid moiety to enhance dermal penetration. It is proposed to stimulate fibroblast activity and upregulate synthesis of extracellular matrix components including collagen types I and III, fibronectin, and hyaluronic acid. The peptide serves as a matrikine fragment mimetic, signaling tissue remodeling pathways in aged or photodamaged skin.
Matrixyl 3000
InvestigationalMatrixyl 3000 is a proprietary combination of two lipopeptides: palmitoyl tripeptide-1 (Pal-GHK) and palmitoyl tetrapeptide-7 (Pal-GQPR). The formulation is designed to synergistically promote collagen and fibronectin synthesis while reducing interleukin-6 mediated inflammation in dermal fibroblasts. Both peptides carry palmitic acid for enhanced lipid solubility and stratum corneum permeation.
