Acetyl Tetrapeptide-9 is a synthetic peptide engineered to target the dermal-epidermal junction, where it promotes the production of collagen XVII and other key structural proteins essential for skin cohesion and firmness. By reinforcing the basement membrane, it helps improve skin density, resilience, and overall structural integrity. This peptide is particularly valued in anti-aging formulations for its ability to counteract sagging and loss of elasticity, delivering a visibly lifted and more toned complexion with consistent use.
