- Matrixyl is the workhorse cosmetic peptide of anti-aging skincare. It signals skin cells to behave as if there has been a small injury — which prompts more collagen and matrix protein production.
What is it?
Matrixyl is the trade name for palmitoyl pentapeptide-4, a lipidated cosmetic peptide widely used in topical anti-aging formulations. Matrixyl 3000 is a related formulation pairing palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7.
In plain English
Matrixyl is the workhorse cosmetic peptide of anti-aging skincare. It signals skin cells to behave as if there has been a small injury — which prompts more collagen and matrix protein production.
How it works
Mimics a fragment of type I collagen, signaling fibroblasts to upregulate collagen, elastin, and glycosaminoglycan synthesis. The palmitic acid tail helps it cross the skin barrier.
