ACETYL TETRAPEPTIDE-15.

Valuable CAS - / SKIN CONDITIONING

Acetyl Tetrapeptide-15 is a neuro-soothing peptide designed to reduce skin sensitivity and discomfort. It effectively increases the skin's tolerance threshold to external stimuli.

soothing

Science

This opioid-mimetic peptide binds to μ-opioid receptors on cutaneous nerve endings, increasing sensory neuron excitation thresholds. This action reduces the release of pro-inflammatory neuromediators like CGRP, thereby decreasing skin hyperreactivity.

Key findings

  1. 01 A clinical study on 20 individuals demonstrated that 0.0015% twice-daily for four days significantly raised the discomfort threshold to capsaicin, effectively reducing skin sensitivity.
  2. 02 A dosage range of 0.2-6% is identified for anti-allergic, anti-inflammatory, and neuro-soothing effects, specifically for improving the skin's tolerance and decreasing nerve sensitivity.
