Iyini indima ye-sebum membrane?

I-membrane ye-sebum inamandla kakhulu, kodwa ihlale indiva. Ifilimu ye-sebum enempilo iyingxenye yokuqala yesikhumba esinempilo, esikhanyayo. I-membrane ye-sebum inemisebenzi ebalulekile yomzimba esikhumbeni ngisho nasemzimbeni wonke, ikakhulukazi kulezi zici ezilandelayo:

1. Umphumela wokuvimbela

Ifilimu ye-sebum iyingqimba ebaluleke kakhulu yokugcina umswakama wesikhumba, engakhiya ngokuphumelelayo umswakama, ivimbele ukuhwamuka ngokweqile komswakama wesikhumba, futhi ivimbele inani elikhulu lomswakama wangaphandle kanye nezinto ezithile ekungeneni. Ngenxa yalokho, isisindo sesikhumba sihlala sijwayelekile.

2. Moisturize isikhumba

Ulwelwesi lwe-sebum aluyona ingxenye ethile yesikhumba. Ikakhulukazi yakhiwa i-sebum ekhiqizwa izindlala ze-sebaceous, i-lipids ekhiqizwa ama-keratinocyte, kanye nomjuluko okhishwa izindlala zokujuluka. Isakazwa ngokulinganayo ebusweni besikhumba futhi yakha ifilimu yokuzivikela yemvelo ebusweni besikhumba. . Ingxenye yayo ye-lipid ithambisa isikhumba ngokuphumelelayo, igcine isikhumba sigcotshiwe futhi sondlekile, futhi yenza isikhumba siguquguquke, sibushelelezi futhi sicwebezele; ingxenye enkulu yefilimu ye-sebum ingagcina isikhumba simanzi ngezinga elithile futhi ivimbele ukuqhekeka okomile.

3. Umphumela wokulwa namagciwane

I-pH yolwelwesi lwe-sebum iphakathi kuka-4.5 no-6.5, ene-asidi ebuthakathaka. Le acidity ebuthakathaka iyenza ikwazi ukuvimbela ukukhula kwama-microorganisms afana namagciwane futhi inomphumela wokuzihlanza esikhumbeni, ngakho-ke ungqimba lwamasosha omzimba ebusweni besikhumba.

Ukukhiqizwa kwezindlala ze-sebaceous kulawulwa amahomoni ahlukahlukene (afana ne-androgens, i-progesterone, i-estrogen, i-adrenal cortex hormone, amahomoni e-pituitary, njll.), phakathi kwawo ukulawulwa kwe-androgens ukusheshisa ukuhlukana kwamaseli e-sebaceous gland, ukwandisa umthamo wabo. , futhi ukwandisa ukuhlanganiswa kwe-sebum; Futhi i-estrogen inciphisa ukukhishwa kwe-sebum ngokuvimbela ngokungaqondile ukukhiqizwa kwama-androgens angapheli, noma ngokusebenza ngokuqondile kuzindlala ze-sebaceous.

Ukuphuma kwe-sebum ngokweqile kungabangela isikhumba esinamafutha, esimahhadlahhadla, izimbotshana ezikhulisiwe, futhi kube nezinkinga zezinduna. Ukukhishwa okuncane kakhulu kungaholela esikhumbeni esomile, ukukala, ukuntuleka kokukhanya, ukuguga, njll.

Izinto ezithinta ukukhishwa kwe-sebum yilezi: i-endocrine, ubudala, ubulili, izinga lokushisa, umswakama, ukudla, umjikelezo wokuphila, izindlela zokuhlanza isikhumba, njll.

I-Meicet skin analyzeringasetshenziswa ukuthola ulwelwesi lwe-sebum lunempilo noma cha. Uma i-membrane ye-sebum incane kakhulu, khona-ke isikhumba sizoba bucayi kakhulu ku-stimuli yangaphandle. Isithombe sizoshuthwa ngaphansi kokukhanya kwe-cross-polarized futhi kusekelwe kulesi sithombeI-MeicetIsistimu isebenzisa i-algorithm ukuze ithole izithombe ezi-3- ukuzwela, indawo ebomvu, imephu yokushisa. Lezi zithombe ezi-3 zingasetshenziswa ukuhlaziya izinkinga zesikhumba ezibucayi.
