Palmitoyl Tetrapeptide-7
Explained
Palmitoyl Tetrapeptide-7 (formerly Palmitoyl Tetrapeptide-3) is a synthetic peptide. Its main job is to fight what researchers call "inflammaging".
"Inflammaging" is the slow, low-grade chronic inflammation that quietly breaks down collagen as we age.
This ingredient calms down a specific inflammation signal in your skin cells (called IL-6). When left unchecked, this signal triggers enzymes that break down collagen and elastin.
Clinical testing showed statistically significant improvements in:
- Skin elasticity
- A reduction in deep wrinkles
- Improved skin texture
Studies also found the more of this ingredient used, the more your skin produces Collagen I, fibronectin, and hyaluronic acid.
You'll likely see this ingredient paired with Palmitoyl Tripeptide-1 in the well-known Matrixyl 3000 complex for enhanced anti-aging effects.
A 3% concentration applied twice daily for two months showed meaningful skin rejuvenation results in clinical panels.
Fungal acne note:
Usually a palmitic acid component can feed Malassezia in unbound form, but here is is covalently bonded to the peptide. This means it is very difficult for Malassezia to access, and therefore very unlikely to cause fungal acne.
