Pal-GHK, also known as Palmitoyl Tripeptide-1 or Palmitoyl Oligopeptide, is a potent anti-wrinkles peptide. It moisturizes the skin, prevents crow’s feet, and regulates trans-epidermal water loss. Pal-GHK peptide impacts skin health, collagen formation, and skin pigmentation. Currently, the peptide is under active review for its effects on increasing and activating collagen synthesis and blood vessel growth.

Pal-GHK is a peptide with a fatty acid end and a peptide end. The GHK-end is the peptide end (Glycine, histidine, and lysine). Meanwhile, the Pal-end is the fatty acid end (Palmitoyl). Pal-GHK peptide is a fibroblast stimulant and a minor component of the elastin protein. As a result, it can boost elastin, collagen, and other extracellular matrix protein synthesis in connective tissues, bone, and skin.

The Benefits and Functions of Pal-GHK Peptide

The robust functions and medical benefits of Palmitoyl Tripeptide-1 are as follows:

  • Pal-GHK peptide tricks fibroblasts into thinking elastin is dead. As a result, the body produces and multiplies fibroblasts at a rapid rate to replenish and regenerate the lost elastin. Pal-GHK peptide also reverses some skin aging effects.
  • When the GHK-end is connected to the Pal-end, the fatty acid (Palmitoyl) end of Pal-GHK acts as an intermediary. This transport complex does an excellent job of improving skin and cell penetration.
  • Pal-GHK peptide activates genes that can change and reset cells to a younger, healthier appearance and state. This can be accomplished by attaching Palmitoyl to the peptide sequence, GHK, which makes it more effective for DNA repair genes and increases the expression of the 14 genes that modulate antioxidant production. Following the genetic changes, the effects of aging are reduced, as are radicals and toxic agents that cause the development of age-related diseases.
  • Pal-GHK peptide was initially a powerful antioxidant. It slows or prevents the progression of Alzheimer’s disease and other age-related diseases. By encouraging angiogenesis—the growth of new blood vessels at the site of injury, Pal-GHK peptide promotes quick wound healing. The peptide both repairs and stimulates the development of new nerves. Furthermore, Pal-GHK peptide improves the actions of wound healing genes. It activates DNA repair genes while suppressing cancer-promoting genes.
  • Pal-GHK peptide is a modified form of the extracellular matrix-derived peptide GHK that can permeate the stratum corneum and attain the epidermal and dermal skin layers.
  • Pal-GHK (0.5 M) increases collagen synthesis in human skin fibroblasts in vitro. It reduces collagen degradation ex vivo in patient-derived human skin samples exposed to UVA light when used at a concentration of 6 ppm.
  • Scientists combined it with the zwitterionic surfactant C12 dodecyl dimethylamine oxide to investigate the composite’s identity into aggregates, ribbons, and nanobelts.
  • Pal-GHK peptide as an internal standard helped quantify pal-KTTKS in anti-wrinkle creams using LC-MS/MS.
  • Scientists believe Pal-GHK peptide can activate age-related DNA repair and healing genes. According to new research, the peptide can influence hair regeneration.

The Pal-GHK Peptide Effect on Wrinkles

  • Pal-GHK peptide can protect the skin from the effects of aging, according to scientific evidence. The peptide accomplishes this by increasing the production of elastin and collagen.
  • Palmitoyl Tripeptide-1 replenishes the skin’s extracellular matrix, reducing wrinkles, smoother skin, and less uneven skin. At the same time, it protects collagen from degradation caused by Ultraviolet A (UVA) rays.
  • Pal-GHK works to replenish lip fullness and moisture. Pal-GHK can work in conjunction with other peptides to reduce the appearance of wrinkles and fine lines. Furthermore, the peptide reduces photodamaged skin redness and discoloration (Melasma).
  • Pal-GHK peptide can be used solely or associated with Palmitoyl tetrapeptide – Z as a potent cosmetic anti-aging active ingredient.

The Adverse Effects of Pal-GHK Peptide

Despite the medical benefits of Palmitoyl Tripeptide-1, the peptide exhibits several adverse effects on the human body.

  • Pal-GHK peptide can irritate the mucous membranes and the upper respiratory tract.
  • Palmitoyl Tripeptide-1 can cause inhalation, skin absorption, or ingestion.
  • Pal-GHK peptide can also cause eye, skin, and respiratory tract irritation.

However, the toxicological properties of this peptide are currently under review. In the case of peptides, it is always best to seek professional medical advice.
