Manufacturing of TNS
Cells from cell banks grow on a 3-dimentional scaffoldCollagen and extra-cellular matrix are produced Growth factors and other essential proteins are secreted into medium.
Growth factors levels are 4000 to 40000-fold higher than a 2-dimentional process
Secreted growth factors are concentrated and stabilized to make TNS

In place of introducing external compounds to mask the signs of skin aging, Biometa Essential Serum™ unlocks one’s own anti aging potential.
Biometa Complex™ has been shown to stimulate “key” proteins and genes within the skin that have been identified as being fundamental to the anti aging cascade; resulting in the improvement of all visible signs of aging
