“Collagen Formation Specialist” A highly concentrated state-of-the-art serum that stimulates the dermal tissue functions. Stimulated dermal tissue function promotes the formation and generation of collagen fibers to provide elasticity and more visibly defined skin contours. Reduces the appearance of dark shadows, especially around the eyes, mouth and chin. Tissue Activator Serum is particularly well suited as a pre- and post-treatment to accompany laser treatments.
