PLLA boasts a well-established safety profile spanning decades. It is a biocompatible, biodegradable, synthetic polymer derived from lactic acid. Widely used in FDA/EMA-approved resorbable sutures, implants, and volumizing dermal fillers (e.g., Sculptra®). Degrades naturally via hydrolysis into lactic acid, metabolized by the body into CO₂ and water.
