Iyini indima ye-sebum membrane?

I-membrane ye-sebum inamandla kakhulu, kodwa ihlala inganakwa. Ifilimu ye-sebum enempilo iyisici sokuqala sesikhumba esinempilo nesikhanyayo. I-membrane ye-sebum inemisebenzi ebalulekile yomzimba esikhumbeni ngisho nasemzimbeni wonke, ikakhulukazi kulezi zici ezilandelayo:

1. Umphumela wesithiyo

Ifilimu ye-sebum iyingqimba ebaluleke kakhulu yokugcina umswakama wesikhumba, engavimba umswakama ngempumelelo, ivimbele ukuhwamuka ngokweqile komswakama wesikhumba, futhi ivimbele inani elikhulu lomswakama wangaphandle nezinto ezithile ukuthi zingangeni. Ngenxa yalokho, isisindo sesikhumba sihlala sijwayelekile.

2. Faka umswakama esikhumbeni

Ulwelwesi lwe-sebum alulona ulwelwesi oluthile lwesikhumba. Luqukethe kakhulu i-sebum ekhishwa yizindlala ze-sebaceous, amafutha akhiqizwa yi-keratinocytes, kanye nomjuluko okhishwa yizindlala ze-sweat. Isatshalaliswa ngokulinganayo ebusweni besikhumba futhi yakha ifilimu yemvelo evikelayo ebusweni besikhumba. . Ingxenye yayo yamafutha ifumisa isikhumba ngempumelelo, igcina isikhumba sigcotshwe futhi sondliwe, futhi yenza isikhumba siguquguquke, sibushelelezi futhi sicwebezele; ingxenye enkulu efilimini ye-sebum ingagcina isikhumba simanzi ngezinga elithile futhi ivimbele ukuqhekeka okomile.

3. Umphumela wokulwa nokutheleleka

I-pH yolwelwesi lwe-sebum iphakathi kuka-4.5 no-6.5, okuyi-asidi encane. Le-asidi ebuthakathaka iyenza ikwazi ukuvimbela ukukhula kwamagciwane anjengebhaktheriya futhi iyazihlanza esikhumbeni, ngakho-ke iyingqimba yokuzivikela ebusweni besikhumba.

Ukukhiqizwa kwezindlala ze-sebaceous kulawulwa ama-hormone ahlukahlukene (njenge-androgens, i-progesterone, i-estrogen, ama-hormone e-adrenal cortex, ama-hormone e-pituitary, njll.), phakathi kwawo ukulawulwa kwama-androgens ukusheshisa ukuhlukaniswa kwamaseli ezindlala ze-sebaceous, ukwandisa ivolumu yawo, nokwandisa ukwenziwa kwe-sebum; Futhi i-estrogen inciphisa ukukhiqizwa kwe-sebum ngokuvimbela ngokungaqondile ukukhiqizwa kwama-androgens angokwemvelo, noma ukusebenza ngqo ezindlaleni ze-sebaceous.

Ukukhiqizwa kwe-sebum ngokweqile kungabangela isikhumba esinamafutha, esinamaqhubu, izikhala ezinde, futhi kube nezinkinga zama-acne. Ukukhiqizwa okuncane kakhulu kungaholela esikhumbeni esomile, ukukhuhla, ukuntuleka kokukhanya, ukuguga, njll.

Izici ezithinta ukukhiqizwa kwe-sebum yilezi: i-endocrine, ubudala, ubulili, izinga lokushisa, umswakama, ukudla, umjikelezo womzimba, izindlela zokuhlanza isikhumba, njll.

Isihlaziyi sesikhumba saseMeicetingasetshenziswa ukuthola ukuthi ulwelwesi lwe-sebum luphilile noma cha. Uma ulwelwesi lwe-sebum luncane kakhulu, khona-ke isikhumba sizozwela kakhulu ezintweni zangaphandle. Isithombe sizothathwa ngaphansi kokukhanya okuphambene futhi sisekelwe kulesi sithombeI-Meicetuhlelo lusebenzisa i-algorithm ukuthola izithombe ezi-3 - ukuzwela, indawo ebomvu, imephu yokushisa. Lezi zithombe ezi-3 zingasetshenziswa ukuhlaziya izinkinga zesikhumba ezibucayi.
