Cov ntaub ntub dej yog cov ntaub so ntswg uas siv los so daim tawv nqaij. Cov ntaub ntub dej ntawm lub khw tuaj yeem muab faib ua ob pawg: ib qho nws tus kheej tau muab tshuaj tua kab mob, tab sis tsis tuaj yeem tua tau lwm yam khoom, uas muaj cov khoom siv tu tawv nqaij, thiab tsuas tuaj yeem ua cov tawv nqaij ntub dej. Lwm qhov tsis yog nws tus kheej yog tshuaj tua kab mob xwb, tab sis kuj tuaj yeem ua lub luag haujlwm ntawm cov tshuaj tua kab mob cov ntaub so ntswg rau lwm yam khoom, uas tuaj yeem siv rau kev tua kab mob lossis ua kom tsis muaj menyuam ntawm daim tawv nqaij abrasions, khawb, thiab lwm yam., Thaum xaiv cov ntaub ntub dej, nco ntsoov saib cov muaj nuj nqi positioning.
Hais txog lo lus tsis muaj zog acid, peb ntseeg tias ntau tus neeg paub txog nws. Muaj ntau lub lag luam siv lo lus los ua ib qho chaw muag khoom hauv lub ntsej muag ntxuav, tshuaj zawv plaub hau thiab lwm yam khoom siv ntxhua khaub ncaws lossis cov khoom tu tawv nqaij kom nyiam cov neeg siv khoom; Tam sim no, nyob rau hauv ib co me nyuam mos cov ntaub so ntswg thiab cov khoom siv pawm, peb kuj feem ntau pom "tsis muaj zog acid" hauv cov lus tshaj tawm. Dab tsi yog qhov qaug zog acid? Puas yog cov khoom tsis muaj zog acidic zoo dua li lwm tus?
1. Lub ntsiab lus ntawm qaug zog acid noo noo so
Cov kua qaub tsis muaj zog hauv cov dej noo yog hais txog cov kua qaub tsis muaj zog ntawm cov tawv nqaij ntawm tib neeg ntawm pH4.5 txog 6.0, uas tuaj yeem ua lub luag haujlwm tiv thaiv daim tawv nqaij los ntawm cov kab mob alkaline thiab cov kab mob ntxeem tau lossis lwm yam stimulation. Tib neeg cov tawv nqaij tau khaws cia rau hauv lub xeev tsis muaj zog acid, uas pab tiv thaiv kev cuam tshuam ntawm qee cov kab mob, tab sis yog tias cov nyiaj tshuav no tawg, nws yuav ua rau cov tawv nqaij tsis muaj zog, thiab ua rau cov kab mob loj hlob, ua rau mob.
2. Cov kua qaub tsis muaj dej noo yog qhov tsim nyog rau tib neeg lub cev
Cov ntaub so ntub dej qee zaum siv ntau yam khoom ntxiv hauv cov txheej txheem tsim khoom. Tom qab ua tiav cov kua qaub, alkali thiab ntsev, cov ntaub so ntub dej yog inevitably acidic lossis alkaline. Yog tias tus nqi pH ntawm cov ntaub so ntub dej yog siab dhau lossis qis dhau, nws yuav ua rau tib neeg noj qab haus huv. Yog tias daim tawv nqaij ntawm tib neeg lub cev feem ntau tsis muaj zog acid, nws yog qhov tsim nyog los tiv thaiv kev cuam tshuam ntawm qee cov kab mob. Yog tias siv cov ntaub so ntub dej uas muaj alkaline muaj zog heev, nws yuav ua rau kev puas tsuaj ntawm lub ntuj barrier ntawm daim tawv nqaij. Qee cov kab mob loj hlob thiab rov tsim dua nyob rau hauv cov kab mob alkaline, txhawb cov tawv nqaij, ua rau tib neeg lub cev tsis zoo, thiab ua rau muaj kab mob.
Yog tias cov kua hauv cov ntaub ntub dej tsis muaj zog acidic, nws yog ze rau pH ntawm tib neeg cov tawv nqaij thiab yuav maj mam thiab tsis khaus thaum siv. Raws li lub teb chaws tus qauv, tus nqi pH ntawm noo noo so rau tib neeg lub cev yuav tsum nyob nruab nrab ntawm 3.5 thiab 8.5. Rau qhov laj thawj zoo, cov kua qaub tsis muaj zog noo noo ua haujlwm zoo dua rau tib neeg lub cev.
3. Xaiv cov ntaub so ntub dej zoo rau tus menyuam, saib pH
Rau cov menyuam mos uas nws cov tawv nqaij tuab tsuas yog 1/3 ntawm cov neeg laus, cov tawv nqaij ua haujlwm tsis muaj zog thiab muaj peev xwm tswj tau cov kua qaub-puag tshuav tsis zoo. Cov zis, quav thiab cov kab mob tag nrho ua rau tus menyuam daim tawv nqaij tiv thaiv. Tus me nyuam daim tawv nqaij, zoo li lwm yam hauv lub cev thiab cov ntaub so ntswg, tsis tau tsim tag nrho hauv cov qauv thiab tsis muaj ntau txoj haujlwm ntawm cov tawv nqaij laus. Nws yuav siv sij hawm tsawg kawg yog 3 xyoos kom paub tab. Nyob rau lub sijhawm no, cov ntsiab lus dej ntawm tus menyuam daim tawv nqaij, sebum secretion, pH ntawm daim tawv nqaij thiab lwm yam tau hloov pauv. Yog li ntawd, cov dej tsis muaj zog ntawm cov menyuam yaus cov ntaub so tuaj yeem tiv thaiv tus menyuam cov tawv nqaij mos ntau dua thiab ua tau zoo.
