Acetyl Tetrapeptide-9 aids in organizing the fibers within the dermis to enhance firmness and recontour the facial structure by targeting lumican, a proteoglycan that plays a role in both the synthesis of collagen fibers and their organization into functional fibers that ensure 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. This results in skin that is firmer, smoother, and more resilient.
