| introduction | palmitoyl tetrapeptide -7(Palmitoyl Tetrapeptide-7) is a synthetic peptide composed of four amino acids, which is used to inhibit the production of excessive cell interleukin (interleukins) in beauty products and cosmetics. This chemical messenger can trigger an acute inflammatory response in the body, leading to glycosylation damage, that is, damage to the process of cross-binding and binding of glucose and protein, and harden the tissue. It has a negative impact on the skin's support system, such as collagen, elastin and other proteins, resulting in wrinkles, relaxation and uneven skin tone |
| Mechanism of action | Palmitoyl tetrapeptide -7( Palmitoyl Tetrapeptide-7) can delay and inhibit the production of excessive cell interleukins, so as to inhibit some inflammation and glycosylation damage that do not have to be inappropriate. In in vitro experiments, the scientists found that during cell interleukin production, "palmitoyl tetrapeptide -7 induction showed a significant dose-dependent reduction. The higher the dose of palmitoyl tetrapeptide -7, the more cellular interleukins are reduced-up to 40%." UV-UV radiation is known to promote the production of cellular interleukins. Cells were exposed to ultraviolet radiation and then treated with palmitoyl tetrapeptide -7( Palmitoyl Tetrapeptide-7), and cell interleukins were seen to reduce 86%. |
| application | palmitoyl tetrapeptide -7 is a key component in Matrixyl 3000 and is used in combination with palmitoyl oligopeptide (Palmitoyl-Oligopeptide). Together, they promote the growth of connective tissue and increase the production of collagen in the skin; when collagen increases, the skin can heal and regenerate itself. |
| Side effects | There are few independent studies on palmitoyl tetrapeptide -7. Its previous name is palmitoyl tetrapeptide -3(Palmitoyl Tetrapeptide-3), which can be found in the cosmetics database of the Environmental Working Group (EWG, quote #3:ewg), it is 100% safe when used in cosmetics and beauty products. |
