\"Pieces<\/figure>\n

GHK-Cu is a tripeptide made up of three amino acids, glycine, histidine and lysine, bound to a copper ion. That is where the name comes from: GHK from the initials of the amino acids, Cu from the chemical symbol for copper. On a cosmetic label you will usually find it under the INCI name Copper Tripeptide-1<\/em>.<\/p>\n

It was discovered in blood plasma in the 1970s. Researchers noticed that its concentration in plasma falls with age, and that is what first sparked interest in it.<\/p>\n

Why copper<\/h2>\n

Copper is a trace element involved in the work of a number of enzymes in the body, including some connected with connective tissue. On its own, a free copper ion is not well suited to cosmetic use: it is reactive and hard to control.<\/p>\n

GHK is a peptide that binds copper and holds it in a stable form. This is why GHK-Cu is classed among the so-called carrier peptides: its role lies not only in the peptide chain itself, but also in the fact that it carries a trace element.<\/p>\n

What the research shows<\/h2>\n

GHK-Cu is one of the most studied peptides in the cosmetic literature. Published work has looked at its effect on collagen and elastin synthesis, on the behaviour of fibroblasts and on healing processes.<\/p>\n

There is one caveat here that often gets left out. Most of that research was carried out on cell cultures, under controlled laboratory conditions, at a precisely defined concentration.<\/strong> A result obtained on cells in a dish does not transfer automatically to human skin, and certainly not to a finished cosmetic product that contains the ingredient at an unknown concentration.<\/p>\n

That does not make the results unimportant. It means they are results about an ingredient, not about a product, and they should be read that way.<\/p>\n

GHK-Cu and the scalp<\/h2>\n

The scalp is skin like any other. It has the same connective layer, the same cells, and it goes through similar changes. That is why an ingredient used in facial care also turns up in products intended for the scalp.<\/p>\n

Scalp care brings one extra practical problem: hair. Liquid applied to the scalp easily ends up on the hair rather than on the skin. This is why scalp products usually come with some form of applicator that helps spread the solution evenly across the skin rather than over the strands. We wrote about this in Dermaroller and microneedling<\/a>.<\/p>\n

Concentrations and stability<\/h2>\n

In cosmetic products GHK-Cu appears at low concentrations, usually expressed in tenths of a percent. There is no universally accepted correct concentration: it depends on the rest of the formulation, the pH value and the purpose of the product.<\/p>\n

Copper peptides are sensitive to storage conditions. For that reason they are often packaged in a form that is prepared shortly before use, rather than sitting in solution for months. That approach is why some products come as a concentrate to be reconstituted rather than as a ready-made solution.<\/p>\n

Combining with other ingredients<\/h2>\n

One practical recommendation comes up often around GHK-Cu: do not apply it at the same time, to the same spot, as strong acids or vitamin C in the form of ascorbic acid. The reason is chemical, an acidic environment can affect the stability of the copper and peptide complex.<\/p>\n

This does not mean those ingredients cannot be used at all, only that it makes sense to separate them in time, for example one in the morning and the other in the evening.<\/p>\n

What GHK-Cu is not<\/h2>\n

GHK-Cu is not a medicine. It is not registered for treating any hair or skin condition, and a cosmetic product containing it must not be presented as a therapy.<\/p>\n

Nor is it a solution for the underlying cause of thinning hair. If hair is falling out suddenly, in clumps, or the shedding comes with itching, redness and changes on the scalp, that is a reason to see a dermatologist, not to reach for a cosmetic product. There is more on this in Hair loss<\/a> and Alopecia<\/a>.<\/p>\n

How to spot it on the label<\/h2>\n

Look for Copper Tripeptide-1<\/em>. Some manufacturers also print the abbreviation GHK-Cu on the marketing side of the packaging, but the INCI name is the one that is mandatory and the one by which the ingredient is genuinely identified.<\/p>\n

Where an ingredient sits on the list says something about the amount: the INCI list is given in descending order by share, while for ingredients below one percent the order does not have to be followed. Peptides are almost always in that lower part of the list, which is to be expected and does not mean there is hardly any of them.<\/p>\n

In short<\/h2>\n

GHK-Cu is a copper tripeptide with a long history in the cosmetic literature. There is a reason for it to appear in a formulation for skin and scalp care, but laboratory findings about an ingredient are not the same as a promise about the result of a finished product. Read the label, pay attention to how the product should be stored, and do not expect cosmetics to do what belongs to the domain of medicine.<\/p>\n

GHK-Cu is one of the three peptides in the SORA peptide hair set<\/a>.<\/p>\n
