Nyeg, pej xeem cov tswv yim siv cov khoom loj (cov dej qab) los yog txhoj puab heev acids (txiv qaub kua txiv) tsis yog siv tsis tau, tab sis kuj tseem txaus ntshai, vim lawv tuaj yeem ua rau tus hniav laus puas.
Yog li, nws tseem muaj peev xwm tswj tau qhov teeb meem uas muaj feem xyuam nrog tsuas yog kev pab los ntawm cov khoom kho hniav tshwj xeeb.
Hom kev txhuam hniav ntawm kev sib tw
Qhov yooj yim cov txheej txheem rau kev tshem tawm cov ntaub yas hniav nyiaj nyom yog sandblasting nrog ib qho kev tov ntawm kev ntsev ntawm cov ntsev ntsev ntawm sodium bicarbonate hmoov. Cov kua yog pub rau hauv siab, uas tso cai rau tshem tawm cov quav , pigmentation thiab me me ntawm lub pob zeb. Cov formations loj loj tsis tshem tawm qhov qauv no.
