Acetyl Tetrapeptide-2

Acetyl tetrapeptide-2 addresses the ageing of the skin’s immune defence: it rejuvenates the activity of Langerhans cells and supports interleukin balance, strengthening the skin’s surveillance and repair capacity that declines from around age thirty. Manufacturer studies additionally document improved firmness and elastic rebound. At 2–5% it is used in firming neck, jawline, and eye products, often combined with matrix-stimulating peptides for a multi-level approach. It is gentle and suitable for thinning, slackening skin. Cumulative use over two to three months yields the most convincing firmness changes — another peptide that rewards consistency.
