Pal-GHK Peptide: Collagen and Wrinkles

Pal-GHK is a synthetic peptide known amongst researchers for its possible impact on collagen, skin cells, and pigmentation. It is also known by the names palmitoyl tripeptide-1 and palmitoyl oligopeptide. Research is now being conducted to determine whether or not it has the capacity to stimulate the formation of blood vessels and whether or not it can increase the amount of collagen that is produced in animal models.

    • Sequence: Palmitoyl-Gly-His-Lys
    • Molecular composition: C30H54N6O5
    • Molecular Weight: 578.8 mol

Pal-GHK Peptide: Research Studies

A portion of the elastin protein is attached to a palmitic acid residue, which lies at the core of the Pal-GHK protein. GHK is sometimes used to refer to this fragment, which is composed of the amino acids glycine, histidine, and lysine. As a result of the fact that GHK has been suggested to increase fibroblast growth and reproduction in animal models, it is of particular relevance to researchers interested in wound healing, skin cell function, and tissue regeneration. Research is now being conducted to determine whether Pal-GHK can improve skin resilience, textural inconsistencies, and structural stability in animal models. Studies suggest that the palmitoyl component gives GHK its potency even though GHK is considered responsible for the peptide’s potential action. The attachment of palmitoyl to GHK is also being researched for its capacity to increase skin and cell penetration in animal models.

Pal-GHK Peptide: Mechanism of Action

The synthetic molecule Pal-GHK is a hybrid compound composed of one part peptide and one part fatty acid. The “Pal” portion of the name refers to palmitoyl, a well-known fatty acid in mammalian cell membranes and a common component. Glycine, histidine, and lysine are the three amino acids that comprise the peptide sequence known as “GHK.” Fibroblasts are cells responsible for synthesizing collagen, elastin, and other essential proteins found in the extracellular matrix of connective tissues, including skin, bone, and other connective tissues. This is a small portion of the much bigger elastin protein and a powerful stimulant of fibroblasts. Incorporating Pal-GHK into study designs containing other short peptides is common practice.

Pal-GHK Peptide: What is it?

Investigations purport that Pal-GHK has a GHK component that may deceive fibroblasts into believing that elastin, a protein often found in skin structures, has been damaged. Because of this, the fibroblasts are stimulated to expand and multiply, allowing them to rebuild what they believe to be the elastin lost in the skin. As animals age, fibroblasts become latent and lose their activity. According to research conducted on animal models, GHK seems to revitalize fibroblasts, which may have the potential to assist in overcoming some of the typical effects of cell aging on the skin. Just like any other vehicle, the Pal component of Pal-GHK is a vehicle. Findings imply it is feasible to induce better skin and cell penetration in animal models by connecting this fatty acid to a peptide sequence. Cell penetration can also be increased. To put it another way, the function of Pal is hypothesized to facilitate the delivery of GHK to the location where it can be of the greatest aid, which is the interior of cells located deep beneath the skin.

Pal-GHK Peptide and Wrinkles

Using animal models, it has been speculated that Pal-GHK may protect the skin from various consequences of cell aging. More specifically, it has been hypothesized that Pal-GHK might increase collagen and elastin formation. Studies suggest that when Pal-GHK is mixed with other short peptides, it may have the potential to work synergistically, reducing wrinkle depth. Experiments conducted on animals have even been indicated to reduce the redness and discoloration of skin caused by photodamage.

Pal-GHK Peptide and Collagen Synthesis

Maquart et al. did research in 1988 that was published in the journal FEBS Letters. This research indicated the potential that underpins the activity of Gly-His-Lys in Pal-GHK.

Research suggests that the formation of this tripeptide sequence, which is suggestive of collagen degradation, may occur as a byproduct during the hydrolysis of these proteins. These fragments, produced as a result of tissue damage, have been theorized to operate as signaling molecules that activate fibroblasts, signaling the beginning of the production of new collagen. It is conceivable that Pal-GHK, which has a sequence similar to Gly-His-Lys, may stimulate the formation of collagen, elastin, and glycosaminoglycans, which are essential components of the skin’s extracellular matrix.

According to the hypothesis put forth by the researchers, the presence of the GHK triplet in the alpha 2(I) chain of type I collagen suggests that proteases may be able to liberate the protein at wound sites, resulting in in situ healing effects.

To provide additional data about Palmitoyl Tripeptide-1‘s potential to stimulate collagen synthesis, a study controlled with a placebo involving 23 research subjects was conducted. The thickness of the skin was employed as a meter, and the findings suggested a slight but statistically significant rise of roughly 4% compared to the placebo. This finding supports the researcher’s hypothesis regarding the peptide’s proposed influence on skin cell regeneration.
