Palmitoyl Tetrapeptide-7

Benefits: Anti-Aging.
Categories: Peptides.

Palmitoyl tetrapeptide-7 is a synthetic peptide composed of the amino acids glutamine, glycine, arginine, and proline. It works as a skin-restoring ingredient and is noted for its soothing ability since it can interrupt factors within skin that lead to signs of irritation (including from exposure to UVB light) and loss of firmness. By working in this manner, skin can regain a firm feeling and engage in repair so that wrinkles will be visibly reduced.

Along with the four amino acids, this peptide also contains the fatty acid palmitic acid to enhance stability and penetration into the skin. Typical usage level is in the parts per million range, which translates to very low, yet highly effective percentages between 0.0001%–0.005%, although higher or lower amounts may be used depending on the formulary goals.

Palmitoyl tetrapeptide-7 is often used as part of a blend with other peptides, such as palmitoyl tripeptide-1. This can produce a nice synergy and offer more targeted results on a wider range of skin concerns.
