PLLA
Pronunciation: P-L-L-A (spell out)
Also written as: PLLA — Poly-L-Lactic Acid
Abbreviation for poly-L-lactic acid, a biodegradable biostimulatory injectable that promotes collagen synthesis over time.
Full Definition
PLLA is the widely used clinical abbreviation for poly-L-lactic acid, a synthetic, biocompatible polymer employed in aesthetic practice to treat facial lipoatrophy and volume loss. The abbreviation appears without periods in contemporary medical literature. Editors should ensure the full form is spelled out on first use in clinical documents and marketing copy. PLLA should not be conflated with other biodegradable injectables such as PDO threads or calcium hydroxylapatite, though all are biostimulatoryagents.
Usage
Usage note: Expand on first use. Do not confuse with 'PLA' (polylactic acid), which lacks the stereospecific L-isomer designation.
