Comparative Physicochemical Characterization of Polylactic Acid-Based Dermal Fillers.
[INTRODUCTION] Polylactic acid can be classified into poly(L-lactic acid) (PLLA) and poly(D,L-lactic acid) (PDLLA) according to their stereoisomeric structures, and both are widely used as dermal fillers for soft tissue augmentation. Althou…

Investigating the Relationship Between the Emulsification Parameters and Physical-Chemical Properties of Poly(D,L-lactic acid) Particles for Dermal Fillers.
Poly(L-lactic acid) (PLLA) and poly(D,L-lactic acid) (PDLLA) particles have been applied as dermal fillers for soft-tissue augmentation because they can induce foreign-body reactions, resulting in fibroblast proliferation and collagen forma…
