Yog tias lub zog siab dhau lawm, qhov zaus tsis tsim nyog, lossis kev tiv thaiv lub hnub tsis siv tom qab txheej txheem, kev kho laser tuaj yeem ua rau tom qab-inflammatory hyperpigmentation (PIH), ua rau melasma hnyav dua li ua ntej. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv ib tus kws kho mob uas muaj kev paub dhau los thiab ua raws li txoj cai "tsis muaj zog, ntau zaus".
Q2: Puas yog picosecond laser zoo dua Q-hloov laser?
A: Los ntawm qhov kev xav ntawm kev txo cov thermal puas, picosecond lasers theoretically muaj qhov zoo dua. Qee cov kev tshawb fawb qhia tias picosecond lasers zoo dua thiab muaj kev pheej hmoo tsawg dua ntawm PIH, tab sis tsis tuaj yeem lav tiv thaiv kev rov tshwm sim. Qhov kev xaiv tshwj xeeb yog nyob ntawm tus kheej hom tawv nqaij thiab cov khoom siv.
Q3: Kuv puas tuaj yeem pom cov txiaj ntsig tom qab ib qho kev kho laser?
