Acetyl Tetrapeptide-22

Product Overview

Acetyl Tetrapeptide-22 is a synthetic peptide composed of four amino acids (Acetyl-Histidine-Leucine-Leucine-Arginine). It is known for its ability to enhance the skin's natural defense against environmental stress by increasing the expression of heat shock proteins, particularly HSP70. This helps improve skin resilience, accelerate recovery after treatments, and reduce visible signs of aging and inflammation.

• Helps soothe and protect stressed or irritated skin.
• Typical usage level is 0.5%–5% depending on formulation needs.
