Science

Mechanism of Action

TRIPEPTIDE-8, specifically Palmitoyl Tripeptide-8, operates by modulating neurogenic inflammation. It achieves this by interfering with the generation of pro-inflammatory cytokines such as IL-8 (interleukin) and TNF-α (tumor necrosis factor), which are central to inflammatory responses and redness. The peptide acts as a biomimetic agent, counteracting the effects of neuropeptides like Substance P, which can induce vasodilation and trigger inflammatory pathways. Furthermore, it inhibits the binding of specific neuropeptides to their receptors and interacts with the melanocortin 1 receptor (MC1-R), thereby reducing the release of inflammatory cytokines and promoting skin soothing. It functions as an anti-allergen peptide, helping to prevent and alleviate neuropathic inflammation and irritation.
