Polylevolactic acid

Iintlobo ze-injection fillers azihlelwanga kuphela ngokwexesha lokugcinwa, kodwa kunye nemisebenzi yazo.Ukongeza kwi-asidi ye-hyaluronic eyaziswayo, enokufunxa amanzi ukuzalisa uxinzelelo, kukwakho neepolymers ze-polylactic acid (PLLA) eziye zasetyenziswa kwintengiso kwiminyaka emininzi eyadlulayo.

Yintoni i-polylactic acid PLLA?

I-Poly (i-L-lactic acid) I-PLLA luhlobo lwezinto ezenziweyo ezihambelana nomzimba womntu kwaye ziyakwazi ukubola.Isetyenziswe njenge-suture efunxayo ngumsebenzi wezonyango iminyaka emininzi.Ke ngoko, ikhuseleke kakhulu kumzimba womntu.Isetyenziselwa inaliti yobuso ukuncedisa i-collagen elahlekileyo.Isetyenziselwe ukugcwalisa izidlele zezigulane ezine-HIV ezinobuso obuncinci ukususela ngo-2004, kwaye yamkelwa yi-US Food and Drug Administration ukunyanga imibimbi yomlomo ngo-2009.

Indima ye-polylevolactic acid

I-collagen esikhumbeni sisakhiwo esiphambili esigcina ulusu luncinci kunye ne-elastic.Ubudala bonyaka bukhula, i-collagen emzimbeni ilahleka ngokuthe ngcembe, kwaye imibimbi iveliswa.I-Molanya - i-polylevolactic acid ifakwe kwindawo enzulu yesikhumba ukuze ikhuthaze ukuveliswa kwe-collagen ye-autogenous.Emva kwekhosi yokutofa, inokuzalisa inani elikhulu le-collagen elahlekileyo, igcwalise indawo etshoneyo, iphucule imibimbi yobuso kunye nemingxuma ukusuka ekujuleni ukuya kubunzulu, kwaye igcine inkangeleko ebuthathaka ngakumbi kunye nobutsha bobuso.

Umahluko omkhulu phakathi kwe-polylevolactic acid kunye nezinye iifayili kukuba ngaphezu kokukhuthaza ngokuthe ngqo ukuveliswa kwe-collagen yamathambo, umphumo we-polylevolactic acid uphuma ngokukhawuleza emva kwekhosi yonyango, kwaye ayiyi kubonwa ngokukhawuleza.Ikhosi yonyango ye-polylevolactic acid ingahlala iminyaka engaphezu kweminyaka emibini.

I-Polylevolactic acid iyona nto ifanelekileyo kwabo bacinga ukuba utshintsho olukhawulezayo luya kubonakala kakhulu, kwaye bafuna ukuphucula ngokuthe ngcembe.Emva kokuphuculwa, abantu abakujikelezile baya kuziva kuphela ukuba uncinci kwaye uncinci kwiinyanga ezimbalwa, kodwa abayi kuqaphela ukuba utyando olwenzileyo.
