1.MECHANISM OF ACTION
- Substance P Inhibition: Its primary action is to modulate the activity of Substance P (SP), a key neuropeptide released in the skin in response to stressors (e.g., UV, pollution, irritants). Substance P triggers inflammation, redness, itching, and vasodilation.
- Receptor Modulation: The peptide is believed to interact with or influence the Neurokinin-1 Receptor (NK-1R), the primary receptor for Substance P. This interaction helps dampen the pro-inflammatory signaling cascade initiated by Substance P binding.
- Reduction of Neurogenic Inflammation: By inhibiting this pathway, Palmitoyl Tripeptide-8 effectively reduces neurogenic inflammation—the inflammation caused by nervous system signals. This leads to decreased cytokine release, less vasodilation (redness), and a lower sensation of discomfort or itching.
2.PRODUCT INDICATIONS
- As a core active in soothing serums, creams, and masks for redness-prone, sensitive, or irritated skin.
- In products targeting rosacea, couperose, and conditions characterized by facial flushing.
- For post-procedure care formulations (after lasers, peels, microneedling) to calm the skin and reduce reactivity.
- In anti-stress and anti-pollution skincare designed to strengthen skin's resilience against environmental aggressors.
- As an ingredient in daily moisturizers and treatments to improve skin comfort and tolerance

3.CLINICAL EFFICACY OF PRODUCT
- Significant Reduction in Skin Redness: Objective measurements (via chromametry) show a decrease in erythema and visible redness.
- Improved Skin Comfort: Subjects report a marked reduction in sensations of stinging, burning, itching, and tightness.
- Enhanced Skin Barrier Function: Helps strengthen skin resilience, as measured by a reduction in Trans-Epidermal Water Loss (TEWL).
- High Tolerance: Demonstrates excellent tolerability even on highly reactive and sensitized skin types.
