CO2 fractional laser therapy theory yog thawj zaug luam tawm los ntawm Tebchaws Meskas Harvard.University kws kho mob laser Dr. Rox Anderson, thiab tam sim ntawd tau txais cov kws tshaj lij thoob ntiaj teb pom zoo thiab kho mob.CO2 fractional laser wavelength yog 10600nm, siv cov txheej txheem xaiv photothermal decomposition, sib npaug ntawm daim tawv nqaij cim nrog cov qhov zoo, ua rau cov tawv nqaij txheej kub stripping, thermal coagulation, thermal nyhuv.Thiab tom qab ntawd ua rau muaj kev cuam tshuam ntawm daim tawv nqaij biochemical los txhawb cov tawv nqaij rau kev kho tus kheej, thiaj li ua tiav firming, rejuvenation thiab tshem tawm cov nyhuv ntawm stains.
