Acetyl Tetrapeptide-2
Ingredient Info
Acetyl Tetrapeptide-2 is a synthetic peptide—a short chain of amino acids—designed to strengthen and firm skin cells. In laboratory studies, it appears to increase the structural stiffness of skin cells, which may contribute to a firmer, more resilient skin appearance.
Benefits
- May increase skin cell firmness and structural integrity
- Potential anti-aging effect through cell-level support
- Well-tolerated in tested concentrations
Science: A 2018 peer-reviewed study using human keratinocyte cells (HaCaT) showed that Acetyl Tetrapeptide-2 consistently increased cell stiffness across tested concentrations, suggesting a firming mechanism. However, evidence is currently limited to laboratory cell studies; human clinical trials are needed to confirm real-world efficacy and safety.
