Mechanism of Action (MOA)
Acetyl Tetrapeptide-11 is a synthetic signaling peptide designed to interact with cellular communication pathways in the skin. It is known to modulate the expression of specific extracellular matrix proteins, including syndecan-1, by influencing keratinocyte signaling. Through this biochemical activity, Acetyl Tetrapeptide-11 supports the maintenance of the skin's structural integrity and cohesion, contributing to optimized cellular interactions within the epidermal environment.
Acetyl Tetrapeptide-11 can be incorporated into a variety of topical cosmetic formulations to enhance product versatility and texture.
