Ukukhuselwa kwefayili
Umphezulu wesikhumba sethu unengubo-i-acid ingubo, eyenza umxube we-sweat kunye ne-fat fat, apho i-acid ekhoyo ikhona-iyenze inkqubo ye-biochemical eyenziwa kwi-epidermis. I-pH yatshintsha kakhulu i-pH yiseli ephilayo kunye ne-bteriki. Njengoko siyazi, nayiphi i-oxidation inefuthe elibi kubomi bayo. Ukumboza iifom zefestile ezifayo zeeseli ezifile, ubuso besikhumba, obunomgangatho oqhelekileyo, luqala ukuphendula kwe-oxidation, izinga le-acidity kule pH ngu-5.5. Oku kukukhusela komzimba kwii-microbes. Nangona kunjalo, ezinye iibhaktheriya zikhetha umxube we-acidic. Nantsi i-lactobacilli-staphylococci, umzekelo, enceda ekwakheni iingubo ze-acidic ngokuveliswa kwe-acids, musa ukubeka ingozi kwesikhumba, ekubeni ikhulula i-toxins kwaye isebenze njenge-antibiotics.
I-alkaline reaction. Isiphumo sayo kwesikhumba
Xa sihlamba ubuso bethu nge-alkaline soap, sisenza umonakalo owonakalisayo kwesikhumba esikhuselekileyo esikhumbeni. Iibhaktheriya ezinobungozi kulolu hlobo ziziva zikhululekile. Kodwa ukubuyiselwa kwengubo ye-acidic kwenzeka kakade malunga neeyure ezimbalwa. Kodwa ngelixa le nkqubela iqhubeka, isikhumba asikhuselwanga kwaye siqala ukudala. Esi sisona sihlandlo esihle kakhulu sokungena mahhala kwesikhumba se-microbes, izifo ezahlukeneyo kunye nemisebe ye-ultraviolet, ephazamiseke kakhulu kwesikhumba. Emva koko, kukho abantu ababukeka bekhulile kuneminyaka yabo ...
Amantombazana amancinci, enqwenela ukuqeda i-acne kunye ne-acne ehlobene neminyaka, qalisa ukusebenzisa isepha, eneeyunithi ezili-11 ze-pH.
Isikhumba esinamanqatha sinomgangatho ohambelana ne-pH yeeyunithi ezi-4 ukuya kuma-5.2, isepha iyingqayizivele yokucaphukisa isithsaba esinamafutha, ngoko ke, ukuphendula okukhuselayo kuqala ukuphuhlisa, oko kukuthi. ulusu lukhupha inani elikhulu leoli. Isangqa esichukumisayo, omnye unokuthi, ngaphandle kwabaphumeleleyo. Kwaye ke, iimveliso zonyusa kuphela kufuneka zisetyenziswe ukucoca ulusu.
Ibhalansi yeAidid. Ukubuyisela ngokukhawuleza
Baya kuhlamba. Kwaye ngoku ubuyisela ubudibanisi besikhumba, usebenzise ezi ngcebiso:
Ukuhlamba umzimba wakho ngesisombululo se-aple cider iviniga kunye namanzi (isipuni esine-viniga kwiikomityi), kunye nokusilalisa awuyi kubuyisela kuphela ukulinganisela kwe-asidi, kodwa kwakhona ukuphucula ukujikeleza kwegazi, ngoko kususa umsila osele kunye nokunika isikhumba sakho ukuqina kunye nobubele. Musa ukulibala ukuba imeko eqhelekileyo yesikhumba yinto ebusweni bayo kwimeko engummangaliso. Kuba i-peeler nayo iyanceda kakhulu iviniga, kodwa ngokuqinisekileyo i-apple.
Ukucoca kunye nokuhlamba umhlanjisi ngamanzi amaninzi, ukuvula izibonda zobuso, oku kuya kukhuthaza ukuxutywa okungcono kwesinye into. Dipha ithawula emanzini afudumeleyo, uyifake kwaye uyifake imizuzu embalwa kwi-shingle. Emva koko, manzi ilinen yelinen kwisisombululo (0.5 ilitha yamanzi kunye ne-50 gruksusa), cindezela uze ufake i-5-7 imizuzu ebusweni, ngelixa ufudumala ngokufaka ithawula elomileyo phezulu. Hlanganisa ngamanzi afudumele. I-Apple cider inepropati yokukhupha isikhumba esiphelile, kwaye ukusisusa ekupheleni kwenkqubo, bayibeke ngobumnene ubuso kunye nethawula elincinci le-terry.
Ukusebenzisa ukhilimu emva kweenkqubo
Kukho iintlobo ezahlukeneyo zesikhumba, kwaye ngokufanelekileyo, i-asidi-base balance is different. Iyakwazi ukusuka kwiiyunithi ezine-4.5. ngesikhumba esomileyo uze ufike kwiinqununu ezingama-5.5. ngesikhumba seoli.
Isepha, nokuba yinto echanekileyo, ayikwazi ukulungisa ibhalansi ye-acid-base. Encinci, iya kuba nefuthe elichaphazelayo kwisakhiwo se-strneum corneum, engasayi kuphuma emanzini, enokutshintsha i-pH yesikhumba. Kuya kuthatha ihora kunye nesiqingatha okanye iiyure ezimbini, njengoko i-pH iya kubuya iphinde ibuyele kwinqanaba layo langaphambili.
Abavelisi ukuba kutheni into ethile ayibonakali rhoqo kwizinga le-pH kwimveliso yeziqholo. Ibonisa nje ukuba ezi zimonyo zilinganayo. Ukuba usebenzisa i-exfoliating, i-peeling okanye i-tonic cream, phawula ingqalelo ye-pH kunye nepesenti ze-acids.
Isisombululo se-asidi, apho i-pH ingaphantsi kweyesithathu, kunokubangela ukuba isikhumba sitshise. Ikhumba elinobuchule nelinen elincinci linokujika libe libomvu kwaye licaphuke xa i-pH ingaphantsi kwe-4.5. Ukuba unesikhumba esinjalo, izimonyo ezine-pH 5.5 ziyimfuneko. Isisombululo se-alkaline kunye ne-pH yeeyunithi ezingaphezu kweshumi elinanye sinokutshatyalalisa kwangoko isikhumba.
Ngaba zikhona iingenelo kwizimonyo ezichukumisayo ?
Abavelisi bezonyiso kule akhawunti banemibono eyahlukileyo. Abanye bakholelwa ukuba i-pH yemveliso yezonyakatho esetyenziselwa ulusu kufuneka ihambelane nesikhumba se-pH-protective skin. Kwaye abanye banquma ukuba i-pH imele ifane neeyunithi ezisixhenxe, oku kuthetha ukungathathi hlangothi. Nangona kunjalo, uluhlu olulodwa lolusu lunalo ibhalansi. Isiqhelo esivamile sihluke kuzo zonke iindawo zesikhumba ngokwe-acidity. Iiseli ezingekho phezulu, kodwa ekujuleni, zinamandla okusebenza ngakumbi ukuze ukwazi ukuma. Iiseli ezifayo zifuna i-pH ye-6.7 ukuya ku-7.3. Ngenxa yesi sizathu, iiseli ze-epidermis ezantsi, zihlanjwe nge-plasma yegazi, zimele zihambelane ne-pH7.1-7.3.
IVotut iphinda ifike ingcamango yokuba kukho isizathu esithile sokungabaza malunga nokusetyenziswa kwamagqabi kunye nemaski enezixhobo eziphathambileyo, izondlo kunye nokuvuselela. Kuye kwenzeka ukuba la mayeza awachaphazeli iindawo ezingaphandle kwesikhumba, kodwa kufuneka angene ngaphakathi kwi-cell cell. Kodwa akukho nto i-acidification. Isiphetho sibonisa imbono yokuba into eninzi kulo mcimbi ihlala ivulekile.
