Polylactic acid (Poly-L-Lactic Acid) has the ability to accumulate water, so the moisture content of tissues after implantation increases and skin firmness is restored. The body reacts to the introduction of the thread by forming connective tissue around it, which provides an increasing tightening effect.
Over time, when PLLA threads are completely dissolved, the connective tissues formed around them also begin to dissolve.
The longevity lasts from 9 months to one and a half years.
