Plla threads:researchers developed PLLA threads after PDO. They used a polymer derived from lactic acid to create them. This material has served widely in orthopedic pins and sutures. PLLA stimulates collagen production for a longer period than PDO.

PLLA threads are absorbable lifting threads made from poly-L-lactic acid.The raw materials are same as sculptra plla filler.Plla thread is  a biodegradable polymer. It stimulates long-term collagen production, improves skin elasticity, and provides lasting lifting effects.
