It is a material that has been well known for many years and is mainly used in the production of sutures. It is fully tested, as today almost all degradative sutures are produced using polylactide. This means that polylactic acid has been proven to be safe on a number of occasions and over a long period of time.


Polylactic acid is used in plastic surgery to eliminate wrinkles and improve the general appearance of the face when there is a lack of facial contour. It is not a filling material, unlike most prolific materials employed in such operations. It is instead a material that stimulates the organism to produce its own collagen. Therefore, it serves more as a stimulant rather than a filling material.

It is employed mostly on more expansive areas (cheeks, cheekbones, jawbones, etc.), but can also be practically applied to limited issues such as wrinkles, etc. It is also used to correct the thin, expansive wrinkles which appear mostly around the cheeks.


P.L.A. is administered by injection. Small amounts should be deposited in the affected area, in several spots, via a thin needle. Usually, a single application will not suffice, requiring 2-4 monthly repetitions.


The final result will not become immediately evident, requiring a period of 4-6 months before signs of improvement begin to appear. This occurs because, as mentioned above, it is not a filling material itself, but must stimulate the organism to produce its own collagen. The production of collagen by the organism requires a certain amount of time, which is why improvement will not be immediately evident.

The duration of the resulting improvement is in the range of one-and-a-half to two years. Afterward, a repetition of the treatment may be sought to renew the result. This is a very safe material, which has been proven not to cause health problems in the long-term.

Polylactic acid is not equivalent to other injectable materials, holding instead a unique position, as it is able to correct problems that other injectables are unable to. Its applications are very specific and it should not be employed for every ailment when it comes to facial aging. A plastic surgeon should make the choice to utilize it based on his own experiences. He or she alone can evaluate whether it is appropriate to apply polylactide or not to a certain case.

The results have been thoroughly satisfying and long-lasting for patients who have shown real signs of improvement thus far. But most importantly, polylactic acid is a safe material.
