Acetyl Tetrapeptide-2 The Neuro-Soothing Peptide for Redness & Rosacea
01
Product Description
1. Mechanism of Action (MOA)
Acetyl Tetrapeptide-2 is a biomimetic peptide specifically designed to target and mitigate neurogenic inflammation, a key driver of facial redness and sensitivity, particularly in conditions like rosacea.
Targeted Inhibition of Substance P Release: The peptide works by modulating the activity of sensory neurons in the skin. It helps to reduce the release of Substance P, a primary neuropeptide that triggers inflammation, vasodilation (widening of blood vessels), and the sensation of itching and burning.
Calculation of Neurogenic Inflammation: By lowering Substance P levels, Acetyl Tetrapeptide-2 effectively interrupts the vicious cycle of neurogenic inflammation. This leads to reduced nerve-induced flare-ups, decreased visible redness, and an overall calming sensation.
Improvement of Skin Barrier Function: Chronic neurogenic inflammation compromises the skin barrier. By calming the nerves, this peptide indirectly supports the repair and strengthening of the skin's natural protective barrier.
In summary, Acetyl Tetrapeptide-2 acts as a "neuro-soother" by specifically targeting the neurological signals that cause redness and irritation, providing a foundational approach to managing reactive skin.
2. In Vitro Efficacy Data
Models: Human keratinocyte cultures, neuronal cell models, and assays measuring Substance P release.
Key Findings:
Dose-Dependent Reduction of Substance P: In vitro studies demonstrated that Acetyl Tetrapeptide-2 significantly and dose-dependently inhibits the release of Substance P from sensory neurons when triggered by inflammatory stimuli.
Downregulation of Inflammatory Mediators: Treatment with the peptide led to a marked decrease in the production of other pro-inflammatory cytokines (e.g., IL-8) in skin cells, confirming a broad anti-inflammatory effect.
Enhanced Barrier Gene Expression: Models showed an upregulation of genes associated with skin barrier integrity, such as those involved in forming tight junctions.
3. Clinical Results
Human clinical studies have validated its efficacy in reducing facial redness and improving the condition of sensitive skin.
Rosacea & Redness-Prone Skin Study (4-8 weeks):
Method: A formulation containing ~3-5 ppm Acetyl Tetrapeptide-2 was applied twice daily by subjects with clinically diagnosed rosacea or self-perceived sensitive skin with redness.
Result: After 4 weeks, instrumental analysis and dermatological assessment showed:
A significant reduction in the intensity and area of facial redness.
A decrease in the frequency and severity of flushing episodes.
Improved overall skin comfort, with subjects reporting less stinging and burning.
Self-Assessment Questionnaires:
Result: Over 80% of participants agreed that their skin felt "more calm," "less reactive," and "soothed" after continued use.
Safety Profile
It is non-irritating, non-sensitizing, and specifically designed for use on fragile and reactive skin. Its mechanism is highly targeted, making it suitable for long-term use.
Compatibility
Synergistic Combinations:
*With Niacinamide: Provides a multi-pathway approach to reducing redness and strengthening the barrier.
