Kungani usebenzisa ukhilimu wobuso?

Njengengxenye ebalulekile nebalulekile yeukunakekelwa kwesikhumbainqubo, inani leukhilimu wobusoKuhlobene kakhulu nezici zomzimba zesikhumba, izinselele eziningi zendawo yangaphandle, kanye nezidingo ezihlukene zabantu abahlukene. Ngokombono wendlela yokugcina umswakama yesikhumba, yize ungqimba lwangaphandle lwesikhumba, i-stratum corneum, lunesibopho sokuvimbela ukulahleka kwamanzi ngokweqile, amandla alo okugcina umswakama ayancipha kancane kancane ngokuguga, izinguquko zemvelo, noma ukunakekelwa kwesikhumba okungafanele. Izakhi ezinamafutha kukhilimu wobuso, njengeVaseline ne-squalane, zingakha isithiyo esincane somzimba ebusweni besikhumba, njengokufaka "ijazi elimanzi" elingabonakali lesikhumba, okunciphisa ngempumelelo ukuhwamuka kwamanzi. Ama-desiccant afana ne-glycerin kanyei-hyaluronic acidNgakolunye uhlangothi, imunca umswakama endaweni ezungezile njengeziponji, igcwalisa i-stratum corneum ngomswakama owanele futhi igcine isikhumba sinamanzi ngaso sonke isikhathi. Ikakhulukazi ekwindla nasebusika, ezindaweni ezomile njengamakamelo anomoya opholile, umswakama womoya uphansi kakhulu, futhi izinga lokulahlekelwa umswakama wesikhumba liyashesha kakhulu. Ngalesi sikhathi, ukhilimu wobuso, onomphumela wawo wokuvala nowokuthambisa oqinile (oqukethe okuqukethwe uwoyela okuphezulu uma kuqhathaniswa neloshini), uba yinto ebalulekile kubantu abanesikhumba esomile noma labo abasendaweni eyomile kakhulu.

Ngaphezu komsebenzi oyisisekelo wokuthambisa, ukhilimu wobuso nawo udlala indima ebalulekile ekuqiniseni isithiyo sesikhumba. Empilweni yanamuhla, izinto ezifana nokuhlanza ngokweqile, izimonyo ezivamile, kanye nokuchayeka emisebeni ye-ultraviolet kungalimaza kalula isithiyo sesikhumba, okuholela ezinkingeni ezifana nokuzwela kwesikhumba, ukubomvu, kanye nokuqhekeka. Izithako zokulungisa ezifana ne-ceramides, i-cholesterol kanye nama-fatty acid aqukethwe kukhilimu wobuso zingalingisa ngokunembile isakhiwo se-sebum, "njengabasebenzi bokwakha", zilungise ngokucophelela ama-lipid phakathi kwamaseli e-stratum corneum, zibuyisele isithiyo sesikhumba esonakele ebuqothweni baso bokuqala, futhi ngaleyo ndlela zithuthukise ikhono lesikhumba lokumelana nezinto zangaphandle. Lesi "sivikelo" esiqinile singanciphisa ngempumelelo umonakalo oqondile esikhumbeni ovela ekungcoleni kwangaphandle, izinhlayiya zezimonyo, njll. Sifaneleka kakhulu kubantu abanesikhumba esibucayi noma labo abanesikhumba esisesikhathini esibucayi ngemva kobuhle bezokwelapha.
Ngaphezu kwalokho, ukhilimu wobuso uyisithwali esihle kakhulu sezithako ezisebenzayo ezahlukahlukene, okwazi ukuhlinzeka ngezixazululo ezinembile zezinkinga zesikhumba ezahlukene. Kubantu abanezidingo zokulwa nokuguga, ukhilimu wobuso oqukethe i-retinol, i-hyaluronic acid, ama-peptide nezinye izithako zifana “nama-mini motors alwa nokuguga” esikhumbeni. Angakhuthaza ukukhiqizwa kwe-collagen, athuthukise imigqa emincane, futhi abuyisele ukuqina kwesikhumba kanye nokukhanya. Kulabo abafuna ukwenza mhlophe, bangakhetha ukhilimu wobuso oqukethe izithako ezifana ne-vitamin C kanye ne-nicotinamide. Lezi zithako zingavimbela ngempumelelo ukwenziwa kwe-melanin, zisize ukulingana kwesikhumba futhi zikhanyise isikhumba. Esikhumbeni esivame ukuvuvukala nokubomvu, ukhilimu wobuso oqukethe izithako eziduduzayo njenge-centella asiatica, i-panthenol, kanye ne-bismyrrh ufana “nomduduzi” omnene, okwazi ukunciphisa ngokushesha ukungakhululeki kwesikhumba. Uma kuqhathaniswa nama-toner nama-essence, ifomula yokhilimu wobuso ivame ukuba nkulu futhi ukuhlushwa kwezithako ezisebenzayo nakho kungaba phezulu. Ngakho-ke, ifaneleka kakhulu esikhumbeni esivuthiwe noma kubantu abadinga ukondliwa okujulile.
Kuhle ukusho ukuthi ukhilimu wobuso awugcini nje esikhumbeni esomile; isikhumba esinamafutha singazuza kuso. Abantu abaningi abanesikhumba esinamafutha bakholelwa ngephutha ukuthi ukuthungwa okujiyile kokhilimu wobuso kuzobangela induna, kodwa empeleni, isikhumba esinamafutha singase sibe nesimo "sokunamafutha ngaphandle futhi somile ngaphakathi". Ukuntuleka komswakama esikhumbeni kuzoshukumisa izindlala ze-sebaceous ukuthi zikhiphe uwoyela owengeziwe. Kuleli qophelo, ukukhetha ifomula engenawo uwoyela noma ukhilimu ofana nejeli (njengemikhiqizo equkethe izithako ze-silane) ngeke nje kunikeze umswakama odingekayo esikhumbeni kodwa futhi kugweme umuzwa wamafutha, ngaleyo ndlela kusize ekulawuleni ibhalansi yamanzi namafutha. Esikhumbeni esihlanganisiwe, indlela yokunakekela enezindawo ingathathwa. Faka i-lotion elula endaweni ye-T kanye nokhilimu othambisayo ezihlathini, ikakhulukazi ukuhlangabezana nezidingo zezindawo ezahlukene zesikhumba.
Ngokuphathelene nokusabela ezinsongweni zemvelo zangaphandle, ukhilimu wobuso nawo udlala indima ebalulekile. Nakuba ukhilimu wobuso ngokwawo ungenazo imisebenzi yokuvikela ilanga, eminye imikhiqizo iqukethe izithako zokulwa nama-antioxidant ezifanai-vitamin Ekanye ne-ferulic acid, engaqeda ngempumelelo ama-free radical akhiqizwa yizici ezifana nemisebe ye-ultraviolet nokukhanya okuluhlaza okwesibhakabhaka, inciphise umonakalo we-oxidative, futhi isize isikhumba ukuthi simelane nokuguga kwe-photoaging. Okwamanje, ebusika lapho umoya obandayo uluma noma ukungcola komoya emadolobheni kukhulu, izithako zokuvala ukhilimu wobuso zingakha ungqimba lokuvikela olubonakalayo ebusweni besikhumba, njengokwakha "umugqa wokuphepha" wesikhumba, kunciphisa umonakalo oqondile wendawo engaphandle engathandeki esikhumbeni.
Abantu abaneminyaka ehlukene kanye nezimo zesikhumba banezidingo ezahlukene zokhilimu wobuso. Isikhumba esincane (esineminyaka engu-18 kuya kwengu-25) ngokuvamile sidinga ukukhetha ukhilimu olula nolunomswakama ukuze kuvinjelwe ukoma nokugcina isimo sesikhumba siphilile. Esikhumbeni esivuthiwe (30+), kuyadingeka ukugxila ekulweni nokuguga nokulungisa okhilimu bobuso ukuze kugcwaliswe i-collagen kanye nemicu enwebekayo ngesikhathi esifanele futhi kuncishiswe inqubo yokuguga kwesikhumba. Phakathi nezikhathi ezithile ezikhethekile, njengangemva kobuhle bezokwelapha (ukwelashwa nge-laser, ukuxubha nge-acid, njll.), isikhumba sisesigabeni sokulungiswa esibuthakathaka. Ngalesi sikhathi, ukusebenzisa ukhilimu wobuso wezokwelapha oqukethe izinto zokukhula kanye ne-hyaluronic acid kunganikeza ukudla okwanele nokusekela isikhumba futhi kukhuthaze ukuphulukiswa kwamanxeba. Lapho izinkathi zonyaka zishintsha, isikhumba sithambekele ekuzweleni. Ngalesi sikhathi, kuyadingeka ukukhetha ukhilimu oduduzayo onezithako ezilula ukuze ugweme ukucasuka ngokweqile futhi usize isikhumba sidlule kahle esikhathini esibucayi.
