Acetyl Tetrapeptide-9 aids in organising the fibres within the dermis to enhance firmness and re-sculpt the facial contours by targeting lumican, a proteoglycan that plays a role in both the synthesis of collagen fibres and their organisation into functional fibres ensuring the integrity of the extracellular matrix. It has been proven to help increase the number of fibroblasts in the dermis, as well as the amount of collagen, elastin and glycosaminoglycans including hyaluronic acid, all of which decrease with age, to natural levels, resulting in skin that is firmer, smoother and more plump.
