Tripeptide is also called blue copper peptide. Tripeptides, a triplet of three amino acids linked by two peptide bonds, rationally block the nerve conduction of a chemical called acetylcholine, which has the practical effect of releasing stress throughout the body muscles and ameliorating dynamic wrinkles. Usually we see copper peptides in blue and purple, in fact only involved in a proportion of the problem.

The theoretical copper peptide is a complex of copper and peptides, including the most common GHK-Cu, (GHK)2-Cu, AHK-Cu, (AHK)2-Cu, GRK-Cu, ARK-Cu, GRF-Cu, AHF-Cu and so on.
But what is the copper peptide that is often referred to? GHK-Cu. GHK tripeptide naturally exists in human blood. It has a small molecular weight, strong fusion ability with receptors, and can reasonably transport copper ions between cells. GHK-Cu was first discovered and extracted by Dr. LorenPickart in the blood of the body and has been used in skin care products for 20 years. The tripeptide Gly-L-His-L-Lys(GHK) and divalent copper ions in human blood have strong infectivity and can spontaneously produce complex copperpeptide (GHK-Cu). Cu + is a critical component for wound healing and many other enzymatic processes.

Copper is an essential trace element to maintain body function (2mg per day). It has many and complex effects and is an essential element for various cellular enzymes. In the efficacy of skin tissue, it has the effect of anti-oxidation, promoting collagen growth, and helping wound healing. Scientists have found that the effect of copper molecule in the removal of skin, is mainly taking advantage of the amino acid complex (peptide) of the medium, so that the divalent copper ion components with biochemical actual effect into the cells, play the endocrine system. GHK-CU is a complex of three carbohydrates and a copper ion found in blood cells. This blue-copper peptide can reasonably promote the production of Collagen and Elastin proteins, improve blood vessel growth and antioxidant capacity. And irritating fructopolyamines (GAGs) are created to assist the skin to respond to its own repairing skill working ability. The discovery and purification of CopperPeptideComplex™ has become the exclusive patent of Neova worldwide. The application of this breakthrough GHK-CU can enhance the charm of cells, slowly repair the collagen from the body without damaging the skin and irritating the skin, so as to make the subcutaneous tissue tough and the wound heal quickly, so as to achieve the goal of wrinkling and anti-aging. The composition of GHK-Cu is Glycyl-L-histidyl-L-lysine-copper. The copper ion Cu2+ is not the yellow of copper metal, but shows blue in solution, so GHK-Cu is also called a blue copper peptide.

Aqueous solution
Copper peptide was first isolated from human blood in 1973 and found to have wound healing properties in 1985. In 1998, researchers suggested that copper peptide and copper complex could act as an activator of tissue remodeling. It is also a signal peptide that can promote the dissolution of many collagen aggregates outside the scar. "All that is normal in the skin is the production of collagen, the conversion of elastin, proteoglycans, and erythrosaminoglycans, the growth rate and migration of different cell types, the anti-inflammatory and anti-oxidative responses."
