Palmitoyl tetrapeptide-7
Palmitoyl tetrapeptide-7 is a lipid-linked GQPR cosmetic peptide, often paired with palmitoyl tripeptide-1. Results for that blend do not establish the contribution of either ingredient alone.
At a glance
- Regulatory status
- Cosmetic ingredient; cosmetic marketing or an ingredient listing is not FDA drug approval. Claims and intended use determine regulatory treatment.
- Research context
- Palmitoyl tetrapeptide-7 is a lipid-linked GQPR cosmetic peptide, often paired with palmitoyl tripeptide-1. Results for that blend do not establish the contribution of either ingredient alone.
What this is
- Palmitoyl tetrapeptide-7 is a lipid-linked GQPR cosmetic peptide, often paired with palmitoyl tripeptide-1. Results for that blend do not establish the contribution of either ingredient alone.
What this isn't
- A recommendation to use, prepare, combine, or administer a product
- Evidence that a related molecule or a differently formulated product has the same effects

It belongs to the skin-conditioning peptide ingredients reviewed by CIR. Claims about matrix support or inflammatory signaling are mechanistic hypotheses; they need to be connected to an outcome measured in the exact finished product. A related peptide's sequence or activity is not interchangeable with this one. Ingredient assessment.
Evidence limits
How to read the evidence
The practical evidence gap is an ingredient-isolating human comparison. A complete guide can explain that gap without turning supplier claims into established benefit. For a mixed serum, the relevant questions are whether the whole product was controlled against its vehicle, whether improvements were visible and durable, and whether adverse effects were tracked. Those answers cannot be inferred from the peptide's presence on a label.
