Yintoni iPLLA (Poly-l-lactic Acid)?

Yintoni iPLA?

Ukutyhubela iminyaka, iipolima ze-lactic acid ziye zasetyenziswa ngokubanzi kwiintlobo ezahlukeneyo zemimandla yezonyango, njenge: i-sutures absorbable, implants ye-intraosseous kunye nokufakelwa kwezicubu ezithambileyo, njl., kunye ne-poly-L-lactic acid isetyenziswe ngokubanzi eYurophu ukunyanga ubuso. ukwaluphala.

Ukwahluke kwizinto ezaziwayo zokuzaliswa kwezithambiso ezifana ne-hyaluronic acid, i-allogeneic collagen kunye ne-autologous fat, i-PLLA (i-poly-L-lactic acid) iyinxalenye yesizukulwana esitsha sezinto zokuvuselela unyango.

Yimathiriyeli yezonyango eyenziwe ngumntu enokuthi ibole kwaye ifunxwe, ikwazi ukuhambelana kakuhle ne-biocompatibility kunye nokonakala, kwaye inokubola ibe yikharbon diokside kunye namanzi ngokwawo emzimbeni.

I-PLLA isetyenziswe ngokubanzi kwicandelo lezonyango malunga neminyaka engama-40 ngenxa yokhuseleko lwayo, kwaye emva kokusetyenziswa kwintsimi ye-aesthetics yonyango, ifumene ngokulandelelana iilayisensi kwii-arhente ezigunyazisiweyo ezilawulayo kumazwe amaninzi:

1. Ngo-2004, i-PLLA yamkelwa eYurophu kunyango lwe-lipoatrophy enkulu yobuso.

2. Ngo-Agasti ka-2004, i-FDA yavuma i-PLLA ukuba ichithwe ukunyanga i-atrophy yobuso enxulumene nosulelo lwe-HIV.

3. NgoJulayi 2009, i-FDA yavuma i-PLLA ukuba ibe yincinci ukuya kwi-nasolabial folds, i-facial contour defects kunye neminye imibimbi yobuso kwizigulane eziphilileyo.

Iimbangela zokwaluphala

Idermis yolusu yenziwe nge-collagen, elastin, kunye ne-glycosamine substances.i-collagen yenza ngaphezulu kwe-75%, kwaye iyona nxalenye ephambili yokugcina ubukhulu besikhumba kunye nokuqina kwesikhumba.

Ukulahleka kwe-collagen sesona sizathu siphambili sokuqhekeka kwenethiwekhi ye-elastic exhasa ulusu, ukucutheka kunye nokuwa kwezicubu zolusu, kunye nokubonakala kwento eyomileyo, erhabaxa, ekhululekileyo, eshwabeneyo kunye nezinye izinto eziguga eluswini!

I-collagen eyaneleyo inokwenza iiseli zolusu zityebe, zenze ulusu lufume, luthambile kwaye lube mpuluswa, kwaye luthintele ngokufanelekileyo ukuguga kolusu.

I-PLA inokuhlangabezana nemfuno yolusuukuvuselelwa kwe-collagen. Inempembelelo ebaluleke kakhulu yokukhuthaza kwizinga lokukhula kwe-collagen, kwaye inokufezekisa ukukhula ngokukhawuleza kwe-collagen density eluswini ngexesha elifutshane, kwaye uyigcinengaphezulu kweminyaka emi-2.

I-PLA inokuphucula ngokufanelekileyo ukuzilawula kwesikhumba, ukulungiswa kunye nokuvuselela imisebenzi ngokuvuselela ukuvuselelwa kwe-collagen kunye ne-elastin, ukunweba ukuthungwa.

Sombulula ingxaki yokunqongophala kokufuma kwidermis kunye nokulahleka kwe-collagen kwingcambu, yenza iiseli zolusu zityebe, kwaye ulusu lubuyele kwimeko yokufuma okugcweleyo, ethambileyo kwaye egudileyo.
