PLLA Cosmetic Threads

The Science

Poly-L-Lactic Acid (PLLA), is a substance which has been used for over 30 years as medical material for tissue regeneration, suture and surgical sealant and more recently was FDA approved in 2009 as an injectable facial rejuvenation treatment to stimulate collagen (commonly referred to as Sculptra®, an injectable facial rejuvenation treatment).  This new generation polymer is extracted from Alpha Hydroxy Acid (AHA) which is known for its absorbability and biodegradability properties.  Now available in a thread form, practitioners can directly address the structure of the face for an immediate lifting effect, accompanied by a longer-term regeneration of collagen and natural volume.  Biodegradation of PLLA occurs through a process of hydrolysis over a time period of between six to eight months while the aesthetic duration of threading results has been found to last between 18-24 months.


Sec. 878.4493 Absorbable poly(glycolide/l-lactide) surgical suture. An absorbable poly(glycolide/l-lactide) surgical suture (PGL suture) is an absorbable sterile, flexible strand as prepared and synthesized from homopolymers of glycolide and copolymers made from 90 percent glycolide and 10 percent l-lactide and is indicated for use in soft tissue approximation. A PGL suture meets United States Pharmacopeia (U.S.P.) requirements as described in the U.S.P. "Monograph for Absorbable Surgical Sutures;" it may be monofilament or multifilament (braided) in form; it may be uncoated or coated, and it may be undyed or dyed with an FDA-approved color additive.
