Yethula:
Eminyakeni yamuva nje, imboni yokunakekelwa kwesikhumba ibone ukwanda kokusetshenziswa kwezithako ezihlukahlukene ezintsha nezizuzisayo. Esinye isithako esinakwa kakhulu yi-titanium dioxide (I-TiO2). Njengoba yaziwa kabanzi ngenxa yemisebenzi yayo eminingi, lesi sakhi samaminerali sesenze izinguquko endleleni esinakekela ngayo isikhumba. Kusukela emandleni ayo okuvikela ilanga kuya ezinzuzweni zayo ezingcono kakhulu zokuthuthukisa isikhumba, i-titanium dioxide isiphenduke isimangaliso sesikhumba. Kulokhu okuthunyelwe kwebhulogi, singena sijula emhlabeni we-titanium dioxide futhi sihlola ukusetshenziswa kwayo nezinzuzo eziningi ekunakekeleni isikhumba.
I-Mastery of the Sun's Shield:
I-Titanium dioxideyaziwa kabanzi ngokusebenza kwayo ekuvikeleni isikhumba sethu emisebeni ye-UV eyingozi. Lesi sakhi samaminerali sisebenza njengesivikelo elangeni esingokoqobo, sakha umgoqo obonakalayo endaweni yesikhumba ebonisa futhi ihlakaze imisebe ye-UVA ne-UVB. I-Titanium dioxide inesivikelo esibanzi esivikela isikhumba sethu emonakalweni obangelwa ukuchayeka elangeni isikhathi eside, esiza ekuvimbeleni ukushiswa yilanga, ukuguga ngaphambi kwesikhathi, ngisho nomdlavuza wesikhumba.
Ngaphandle kokuvikela ilanga:
Nakuba i-titanium dioxide yaziwa kakhulu ngezici zayo zokuvikela ilanga, izinzuzo zayo zidlulela ngale kwezindawo zayo zokuvikela ilanga. Le nhlanganisela ehlukahlukene iyisithako esivamile emikhiqizweni ehlukahlukene yokunakekelwa kwesikhumba, okuhlanganisa isisekelo, impushana, ngisho ne-moisturizer. Inikeza ukufakwa okuhle kakhulu, isiza ngisho nethoni yesikhumba futhi ifihle ukungapheleli. Ngaphezu kwalokho, i-titanium dioxide inamandla amahle kakhulu okusabalalisa ukukhanya, okwenza ibala likhazimule futhi lidume phakathi kwabathanda izimonyo.
Ilungele isikhumba futhi iphephile:
Isici esiphawulekayo se-titanium dioxide ukuhambisana kwayo okuphawulekayo nezinhlobo ezahlukene zesikhumba, kuhlanganise nesikhumba esibucayi nesithandwa yizinduna. Akuyona i-comedogenic, okusho ukuthi ngeke ivale ama-pores noma ibe yimbi nakakhulu ukuphuma. Imvelo emnene yalesi sakhi iyenza ifanelekele abantu abanesikhumba esisebenzayo noma esicasuliwe, okubavumela ukuba bajabulele izinzuzo zayo eziningi ngaphandle kwemiphumela emibi.
Ukwengeza, iphrofayili yokuphepha ye-titanium dioxide ithuthukisa nakakhulu ukukhanga kwayo. Kuyisithako esigunyazwe yi-FDA esithathwa njengephephile ukuze sisetshenziswe abantu futhi sitholakala emikhiqizweni eminingi yokunakekelwa kwesikhumba ethengiswayo. Kodwa-ke, kufanelekile ukuqaphela ukuthi i-titanium dioxide efomini le-nanoparticle ingase ibe isihloko socwaningo oluqhubekayo mayelana nemiphumela engaba khona empilweni yomuntu. Njengamanje, abukho ubufakazi obanele bokunquma ngokuqinisekile noma yiziphi izingozi ezihlobene nokusetshenziswa kwayo emikhiqizweni yokunakekelwa kwesikhumba.
Ukuvikelwa kwe-UV okungalandeleki:
Ngokungafani nama-sunscreens avamile avame ukushiya uphawu olumhlophe esikhumbeni, i-titanium dioxide inikeza isisombululo esijabulisa kakhulu. Ukuthuthuka kwezinqubo zokukhiqiza i-titanium dioxide kubangele usayizi wezinhlayiyana ezincane, okubenza bacishe bangabonakali lapho besetshenziswa. Le ntuthuko ivula indlela yamafomula abukeka kahle ahlangabezana nezidingo zalabo abafuna isivikelo esanele selanga ngaphandle kokuphazamisa ukubukeka kwebala labo.
Ekuphetheni:
Akungabazeki ukuthi i-titanium dioxide isiyisithako esibalulekile nesithandwayo ekunakekelweni kwesikhumba. Ikhono layo lokuhlinzeka ngokuvikelwa kwe-UV ebanzi, ukuthuthukisa ukubukeka kwesikhumba, nokuhambisana nezinhlobonhlobo zezinhlobo zesikhumba kugqamisa ukuguquguquka nokusebenza kwayo okuhlukahlukene. Njenganoma yisiphi isithako sokunakekelwa kwesikhumba, kufanele sisetshenziswe njengokuqondiswa nokunaka noma yikuphi ukuzwela komuntu siqu. Ngakho-ke yamukela izimanga ze-titanium dioxide futhi ukwenze okuyisisekelo esimisweni sakho sokunakekela isikhumba ukuze unikeze isikhumba sakho ungqimba olwengeziwe lwesivikelo.
