ACETYL TETRAPEPTIDE-22.

Valuable CAS - / SKIN CONDITIONING

Acetyl Tetrapeptide-22 is a precision peptide engineered to enhance the skin's resilience against environmental stressors. It promotes cellular homeostasis and aids in the recovery of damaged proteins, making it beneficial for stressed or sensitive skin types.

Summary

Skin conditioning Soothing Stress tolerance enhancement Collagen stimulation Anti-inflammatory

Science

Mechanism of Action

This peptide functions by inducing the expression of Heat Shock Protein 70 (HSP70), a molecular chaperone. HSP70 repairs damaged proteins and strengthens the skin's tolerance to environmental aggressors like UV radiation and temperature extremes, while also stimulating collagen and reducing inflammation.
