CO2 fractional laser tshuabsiv RF raj thiab nws txoj cai ntawm kev ua yog focal photothermal nyhuv. Nws siv lub ntsiab lus tseem ceeb photothermal ntawm laser los tsim ib qho array zoo li kev teeb tsa ntawm lub ntsej muag luag ntxhi uas ua rau ntawm daim tawv nqaij, tshwj xeeb tshaj yog cov txheej txheem dermis, yog li txhawb kev tsim ntawm collagen thiab kev hloov kho ntawm collagen fibers hauv dermis. Txoj kev kho no tuaj yeem tsim ntau yam peb-dimensional cylindrical luag nyav raug mob nodules, nrog cov ntaub so ntswg tsis zoo nyob ib ncig ntawm txhua qhov chaw luag nyav raug mob, ua rau cov tawv nqaij pib kho cov txheej txheem, txhawb cov kev tshwm sim xws li epidermal regeneration, kho cov ntaub so ntswg, collagen rearrangement, thiab lwm yam., ua kom cov kev kho mob hauv zos sai.
CO2 dot matrix laser tshuabfeem ntau yog siv los kho cov tawv nqaij thiab rov tsim kho dua tshiab los kho ntau yam caws pliav. Nws cov nyhuv kho yog tsuas yog los txhim kho qhov smoothness, kev ntxhib los mos, thiab xim ntawm caws pliav, thiab alleviate sensory abnormalities xws li khaus, mob, thiab loog. Qhov laser no tuaj yeem nkag mus tob rau hauv cov txheej txheem dermis, ua rau muaj kev tsim dua tshiab, collagen rov kho dua, thiab kev loj hlob lossis apoptosis ntawm caws pliav fibroblasts, yog li ua rau cov ntaub so ntswg txaus kho thiab ua si lub luag haujlwm kho.
