I-Science elula Yokuba Kutheni Ufumana Izipho
Iingqungquthela ezixhambileyo ziyingxenye yunithi ye- pilosebaceous equlethe i- follicle , i-hair shaft, kunye ne-erector second muscle ejongene ne-goosebumps. Iinqununu zeplacebaceous zifunyanwa yonke indawo emzimbeni ngaphandle komlomo ophantsi, iintendelezo zezandla, kunye neentonga kunye neengcambu zeenyawo. Iindawo eziphambili kakhulu (kwaye iindawo ezibonakalayo zihlala zibonwa) zikho ubuso, isikhumba, intamo ephezulu kunye nesifuba.
Iingqungqungquthela ezixhambileyo zivelisa i- sebum , into enamafutha eline-triglycerides, i-wax, i-squalene kunye nama-fatty acid acids. I-Sebum igcina isikhumba kunye neenwele zihluthwa kwaye zenza njengendlela yokukhusela ukungena kwamanzi ukukhusela ukuba ibe yomelele kwaye ibuhlungu. Kananjalo yenza umsebenzi obalulekileyo ngokuthintela ukukhula kwama-microorganism esikhumbeni.
Umbutho Phakathi kweSebum kunye ne-Acne
Nangona izilonda zongqingili zivelisa inani elifanelekileyo le-sebum ukugcina ulusu kunye neenwele zihluma, ngamanye amaxesha azisebenzi kakuhle njengoko kulindeleke.
Ngokomzekelo, ukuveliswa kwe-sebum kuyancipha kwinqanaba elingama-20. Ngeengqungquthela ezingenakukwazi ukuvelisa i-sebum ngokwaneleyo rhoqo, ulusu luyakuma kwaye lulahlekelwe ukuqina. Esi sizathu sezizathu zokuba ubumba besikhumba luguquka njengoko ukhula.
Ngapha koko, utshintsho lwe-hormone olwenzeka ngexesha lokutshatyalaliswa kwexesha lubangela ukuba izigulane ezixhambileyo zandise kwaye zenze i-sebum ngaphezulu.
Oku kutshayisana, kuhlanganiswe nokutyhala kweeseli zesikhumba ezifile, kunokuvala i-follicle pores kunye nokuvelisa isikhumba samanzi, esibizwa ngokuba yi-seborrhea. I-acne ingahlakulela xa i-sebum ibophekile ngaphakathi kwezi pores, ekhokelela ekugqibeleni ngokuqhelekileyo kweempuphu eziselula.
I-Sebum inokubangela ukuba iinwele zivele zibala xa zingavunywanga iintsuku eziliqela.
Iimbopheko, okwangoku, zinohlobo lwazo lwezilwanyana ezinqabileyo (ezibizwa ngokuba yi-mebomian glands) ezibethelela uhlobo oluthile lwe-sebum kwiinyembezi. Xa iinyembezi ziqokelele, zivelisa ukukhutshwa kwe-mucousy ezingakwazi ukunyuka, zikhokelela ekukhutsheni okuqhelekileyo esikufunyenwe rhoqo kumacandelo ethu emva kokulala.
Indlela i-Acne ikhula ngayo
Iifolda zakho ziyimishini yokucoca. Benza umsebenzi omkhulu wokucoca udoti, ioli kunye neeseli zesikhumba ezifile. Kodwa xa le nkqubo ingasebenzi njengoko kufanelekile, yonke loo ngcola ingabanjwa.
I-Sebum inikeza umswakama elukhumbeni nasezinyaweni ngokuhambisa i-hair shaft kunye ne-open follicle. Nangona kunjalo, kukho amaxesha apho i-sebum ikwazi ukwenza njengeglue ngokubambelela kumaseli esikhumba efile phezu kwesikhumba. Ngokubambisana, lo bunzima bekhumba kunye ne-sebum ngokukhawuleza uvimba i-follicle ukuvula, njengokuba izigulane ezizihlambululayo ziqhubeka zikhupha i-sebum.
Njengoko iibhaktheriya ziqala ukuphumelela kwi-pore, isistim somzimba siphendula ngokuthi senze i-pimple ezaliswe ngumbhobho (inhlanganisela ye-sebum, iiseli zesikhumba ezifile kunye neeseli zegazi ezimhlophe) kwindawo yesifo. I-pimple iya kuba yinto ebomvu kwaye ivuke njengamajoni omzimba ekuhlaseleni kwaye ibulale ibhaktheriya, ekhokelela ekuphulukeni kokugqibela kwintolli kunye nezicubu ezijikelezayo.
