Matrix PDO Threads are another method of tightening and thickening skin. They are a type of single PDO filament, are smooth and made from Polydioxanone.

Matrix PDO Threads are inserted into the sub dermal level, in a mesh-like pattern, to promote the creation of new collagen. The threads activate collagen synthesis, which produces a gradual skin thickening, skin tightening and rejuvenation effect. The threads become a support structure that allows collagen production to increase.
