Acetyl Tetrapeptide-2: supporting the look of firm, dense skin

Acetyl tetrapeptide-2 is a peptide made of four amino acids with an acetyl group attached. It is used in skincare to help skin look firmer, denser and more resilient, particularly where skin has started to lose its spring.

What it is

The acetyl group helps protect the peptide and keeps it stable within a formula. Like other cosmetic peptides, it is designed to act as a messenger rather than a structural ingredient.

What the research looks at

As skin ages, it gradually loses elasticity and density, which shows as slackness along the jaw and neck. Laboratory studies have looked at acetyl tetrapeptide-2 for its role in the proteins associated with skin elasticity and cohesion. In cosmetic use, it is chosen to improve the look of firmness and tone.

Why it is in Vellura

Acetyl tetrapeptide-2 is one of the five peptides in The Cervical Elixir, where it complements palmitoyl tripeptide-5 with a firmness and elasticity signal. It is dosed in the ranges its suppliers recommend and published studies use.
