Compared to PLLA which is conventionally used for collagen stimulation, PDLLA is a more versatile option. In addition to collagen stimulation, PDLLA can be used for skin tightening, reducing enlarged pores, appearance of scars and more.
It is also safer as PLLA is composed of irregular broken crystal shapes and their sharp edges can cause intense inflammatory reactions, resulting in overproduction of collagen and thus granulomatous reactions (nodules and bumps under the skin). On the other hand, PDLLA’s spherical and foamy shape guarantees better tissue compatibility and therefore lowers the risks of side effects.
