Acetyl Tetrapeptide-11
Acetyl Tetrapeptide-11 is a synthetic peptide used in anti-ageing skincare to help improve skin firmness and smoothness. It is commonly found in serums, creams and eye treatments aimed at mature skin. Shoppers like it for its ability to support a more youthful-looking complexion without irritation.
How it works in skincare
In cosmetics and skincare Acetyl Tetrapeptide-11 works by signalling to skin cells to support the production of key structural components such as collagen and elastin. When applied topically it helps reinforce the dermal-epidermal junction, improving skin cohesion and resilience. Formulators value its ability to deliver visible firming and smoothing results in lightweight, non-greasy textures suitable for daily use.

Acetyl Tetrapeptide-11 is a lab-made peptide created by combining four amino acids and acetylating the chain for greater stability. It is not derived from a plant, seed, flower or mineral source but is produced through controlled synthesis for use in cosmetic formulations.
