Palmitoyl Tetrapeptide-7 is a synthetic peptide comprised of four amino acids that is used in beauty products and cosmetics to suppress the production of excess interleukins, the chemical messengers which trigger the body’s acute inflammatory response. Up to about age 35 when hormone levels begin to drop, very little interleukin is secreted and its secretion is strictly controlled.

One study re: Palmitoyl Tetrapeptide-7

In vitro, the Ultra Aesthetics scientists found that PT-7 induced a marked dose-dependent reduction in interleukin production. The higher the concentration of Palmitoyl Tetrapeptide-7, the greater the reduction in interleukin production – up to 40%.

UV radiation is known to accelerate interleukin production. When the scientists exposed cells to UV radiation and then added PT-7, they achieved an 86% reduction of interleukin production.

These results show that PT-7 is able to affect baseline levels of interleukin as well as modulate the effects of UV-stimulated over-production.



There are very few independent studies available on Palmitoyl Tetrapeptide-7.

A great youtube video on peptides.
