WHAT'S PLLA?

Poly(L-lactide)，it is a good bioabsorbable and biocompatible material,it's degarded in the body, the final substance changes into carbon dioxide and water out of the body. So there are no side effects. PLLA is uesed in medicine widely now, such as disposable infusion equipment,surgicla sutures, drug delivery carrier, tissue engineering scaffold, bone anchor, injectable microcapsule, Micoballon, Implant, Organ support for elastomer materials, etc.














★Manufacturing Process

PLLA ( Poly-L-lactic acid ) is formed by ring-opening polymerization of l-lactic acid which is produced by starch fermentation.

★Material safety

PLLA stimulation for the production of new collagen has been clinically recognized worldwide. PLLA has been FDA approved since 1999 and has been used as an important facial filling material.

PLLA does not have staining problems and its composition is beneficial to the human body.

★Principle

Poly (L-lactic acid) induces fibroblasts to actively regenerate dermal matrix components such as collagen after the immune response in tissues.Poly L-lactic acid) will gradually degrade into lactic acid in the tissue, and then metabolize into water and carbon dioxide out of the body.

Stimulate fibroblast activity
PLLA stimulates dormant or quiescentfibroblasts to become convalescentfibroblasts.
The recovered fibroblasts are full ofcellular activity
Regeneration of collagenand hyaluronic acid
Active fibroblasts will produce:.CollagenElastin·Hyaluronic Acid.Growth factorProteaseIntercellular substance
Slowly and imperceptibly young
After receiving 2-3 times of continuousstimulation, the active fibroblasts willcontinuously produce collagen and othersubstances for 3-6 months, graduallyrepairing the lost dermal structure
To restore the firming andplump skin of youth
The structure of collagen and otherfibroblast exosomes will reconstruct theaged dermal tissue, making it full andtight as when it was young
