Used in facial treatments, this Tetrapeptide stimulates the synthesis of syndecan-1 and collagen XVII by keratinocytes. The syndecan-1 is a small skin proteoglycan that plays a role in strengthening the cohesion of the epidermis. The collagen XVII improves adhesion between the epidermis and the dermal-epidermal junction. This Tetrapeptide is recommended in caring for mature skin because it helps improve skin firmness, skin elasticity and appearance of the skin.
