Overview
Penetrates stratum corneum due to palmitoyl group, binds to integrin receptors on fibroblasts.
Proposed mechanism
Palmitoyl tripeptide-1 mimics a fragment of laminin α1 chain, signaling fibroblasts to produce collagen, fibronectin, and hyaluronic acid.
What the evidence supports
Human data exists but the trials are small, short-term, or not yet replicated.
Graded Human-limited
Human data that exists but is thin: open-label work, single-arm studies, small cohorts, or observational follow-up without randomisation.
