Product Name: Pal-Tripeptide-1; Pal-GHK INCI Name: PALMITOYL TRIPEPTIDE-1 Molecular Formula: C30H54N6O5 Molecular Weight: 578.79 Appearance: White crystalline powder Purity: 99% CAS Number: 147732-56-7 Standard: Enterprise Standard Supplier: ZhenYiBio Palmitoyl tripeptide-1 is a small three-amino acid signal peptide with the amino acid sequence of Glycine-Histidine-Lysine (GHK). GHK attaches to palmitic acid (a fatty acid) to increase its skin permeability and oil solubility. Applying palmitoyl tripeptide-1 directly to the skin can stimulate the cells to produce more and newer collagen. It takes at least 1 month or more to start seeing visible changes in new collagen.
Product Name: Acetyl Hexapeptide-1 Other Name: N-Acetyl-L-norleucyl-L-alanyl-L-histidyl-D-phenylalanyl-L-arginyl-L-tryptophanamide Molecular Formula: C43H59N13O7 Molecular Weight: 870.01 Appearance: White powder Purity: 99% CAS Number: 448944-47-6 Standard: Enterprise Standard Supplier: ZhenYiBio Acetyl hexapeptide-1 is a synthetic peptide composed of the amino acids alanine, arginine, histidine, leucine, phenylalanine and tryptophan. It has a calming effect and helps the skin better resist environmental aggressions. Acetyl Hexapeptide-1 (Acetyl Hexapeptide-1) has affinity for MC1-R. It is a biomimetic peptide that mimics �±-MSH. It can promote melanin production by combining with MC1-R, so it can be used as a natural Photoprotective factors and inflammation modulators. At the same time, it can also promote the transfer of melanin from melanocytes to keratinocytes, so it can promote skin or hair coloration.
