Daim Ntawv Thov

‌1. Kev kho kom zoo nkauj kho mob: PDLLA yog siv dav ua cov khoom siv rau lub ntsej muag hauv kev kho kom zoo nkauj kho mob vim nws qhov kev sib haum xeeb zoo heev thiab kev puas tsuaj. Nws tuaj yeem txhawb kev tsim cov collagen ntawm daim tawv nqaij, yog li txhim kho daim tawv nqaij sagging, wrinkles thiab kev nyuaj siab.

‌2. Cov khoom siv kho mob: PDLLA kuj tseem siv dav hauv kev kho mob, xws li cov tshuaj pleev xim rau cov hlab ntsha uas lwj tau, cov xov phais, cov ntaub thaiv hemostatic, thiab lwm yam. Nws qhov kev sib raug zoo thiab kev lwj tau zoo ua rau cov khoom siv kho mob no muaj kev nyab xeeb dua thiab ua haujlwm tau zoo dua thaum siv.

‌3. Kev tsim cov ntaub so ntswg: PDLLA kuj muaj cov ntawv thov tseem ceeb hauv kev tsim cov ntaub so ntswg, xws li kev kho pob txha thiab cov ntaub ntawv kho pob txha, cov khoom siv tsim cov ntaub so ntswg, thiab lwm yam. Nws cov qauv porous yog qhov zoo rau kev txuas thiab kev loj hlob ntawm cov hlwb, yog li txhawb kev kho cov ntaub so ntswg thiab kev rov ua dua tshiab.

4. Kev tso tshuaj tswj: PDLLA kuj tseem siv tau rau kev tso tshuaj tswj thiab kev ntim khoom tso tshuaj mus ntev. Los ntawm kev sib xyaw nrog cov tshuaj los ua cov qauv tshuaj xws li microspheres lossis microcapsules, kev tso tshuaj qeeb thiab kev ua haujlwm ntev ntawm cov tshuaj tuaj yeem ua tiav, yog li txhim kho kev ua haujlwm thiab kev nyab xeeb ntawm cov tshuaj.

‌5. Kev ua haujlwm puas tsuaj ntawm PDLLA‌: PDLLA puas tsuaj qeeb qeeb, uas ua rau nws muaj peev xwm muab cov txiaj ntsig kho mob ntev dua hauv kev siv kho mob. Nws cov khoom puas tsuaj yog lactic acid, uas thaum kawg metabolized rau hauv carbon dioxide thiab dej, thiab tsis muaj tshuaj lom thiab tsis ua rau tib neeg lub cev puas tsuaj
