Sicebisa ukuba ukhuselo lwelanga yenye yezona ndlela zilungileyo zokuthintela ulusu lwakho ukuba lungaluphali ngaphambi kwexesha kwaye kufuneka lube ngumgca wakho wokuqala wokuzikhusela ngaphambi kokuba sifumane iimveliso zokhathalelo lolusu eziqinileyo. Kodwa abathengi bathi abazinxibi i-sunscreen kuba banenkxalabo yokhuseleko malunga nezithako ezikwiimveliso zokukhusela ilanga.
Ukuba awuqinisekanga, qhubeka ufunda umahluko phakathi kwe-suncream yeekhemikhali kunye ne-physical (mineral) kunye nesizathu sokuba sicinga ukuba i-suncream yeminerali yeyona ilungileyo ukuyisebenzisa eluswini lwakho.
Kodwa okokuqala, kubalulekile ukucacisa igama elithi chemical kuba ngamanye amaxesha kunokubakho ingcamango ephosakeleyo yokuba zonke iikhemikhali ziyingozi. Nangona kunjalo, thina, nayo yonke into esingqongileyo yenziwe ngeekhemikhali, nokuba amanzi ayikhemikhali umzekelo, ngoko ke akukho nto inokuthathwa njengengenazo iikhemikhali. Apho kukho uloyiko malunga nezithako zokhathalelo lolusu, oku kuqhele ukubhekisa kwinto eyenziwe ngeekhemikhali eziyingozi. Kule meko, singasebenzisa isigama esithi, 'esingenabungozi' xa sigxininisa iimveliso ezamkelwe ngokubanzi ukuba zikhuselekile ukuzisebenzisa.
Yintoni i-sunscreen yamakhemikhali?
Iikhemikhali zokukhusela ilanga zisebenza ngokufunxa eluswini kwaye xa imisebe ye-UV idibana ne-suncream kwenzeka impendulo ephelisa imisebe ye-UV ngaphambi kokuba umonakalo wenzeke eluswini lwakho. Zibizwa ngokuba yikhemikhali, kuba kukho ikhemikhali eyenzekayo ukubonelela ngokhuseleko elangeni.
Izithako ezisetyenziswa kakhulu yi-oxybenzone, i-avobenzone, kunye ne-octinoxate kwaye nangona amagama azo kunzima ukuwabiza, ezi zithako zisebenza njengesiponji ukuze zifunxe imisebe ye-ultraviolet eyingozi.
Yintoni i-sunscreen yeminerali?
Izithambisi zelanga ezineeminerali nezomzimba ziyafana kwaye zihlala phezu kolusu kwaye zisebenza njengesithintelo esibonakalayo kwimitha yelanga. Izithambisi zelanga ezibonakalayo zisebenzisa izithako ezimbini zendalo ezisebenzayo - i-zinc oxide kunye ne-titanium dioxide - kwaye ngokubanzi zinezithako ezimbalwa kuzo kunee-sun lotions zeekhemikhali.
Ungazi njani ukuba i-sunscreen yiminerali okanye yikhemikhali?
Ungabona ukuba loluphi uhlobo lwe-sunscreen onayo ngokujika ibhotile okanye ijagi uze ujonge uluhlu lwe-INCI (izithako) ngasemva kwephakheji ukuze ujonge izithako ezisebenzayo.
Kutheni ukhetha i-sunscreen yeminerali?
Njengoko besitshilo apha ngasentla, abanye abantu banenkxalabo ngokhuseleko malunga nezithako ezinobungozi kwi-suncreams zamakhemikhali ngoko ke bakhetha ukusebenzisa ii-SPFs zeminerali kuba zihlala phezu kolusu endaweni yokufunxwa kulo. Ngaphandle kweengxaki zezithako, iintlobo zolusu ezibuthathaka, okanye abo bane-allergy kwezinye ii-sun lotions okanye abantu abane-acne banokukhetha izithako ezithambileyo kwi-sun creams zeminerali kunye noluhlu lwezithako ezimfutshane.
Emva koko kukho indlela yokusebenzisa. Ukuba urhawuzelelwa kukuphuma naphi na kwiimeko zemozulu, ungakhetha ukusebenziseka lula kwee-suncreams zeminerali kuba, ngokungafaniyo nee-sun creams zekhemikhali, ekufuneka zifunxwe ngokupheleleyo eluswini ngaphambi kokuba zisebenze (zithatha imizuzu eli-15), ii-sunscreens zeminerali ziyasebenza kwangoko emva kokuba zisetyenziswe.
Iingenelo zee-mineral sun creams
Ayinamanzi xa isetyenziswa eluswini – nokuba yi-suncreams yeekhemikhali okanye zeminerali kufuneka uphinde uyifake xa uphuma edamini okanye elwandle.
Ukhuseleko lwe-UVA kunye ne-UVB – i-zinc oxide, isithako esisebenzayo kwi-suncream yeminerali, iyakwazi ukufotwa lula ngoko ke inika ukhuseleko oluhle lwe-UVA kunye ne-UVB njengoko ingalahlekelwa ngamandla ayo okukhusela xa ichaphazeleka kukukhanya kwe-UV. Oku kubalulekile ekuthinteleni ukwaluphala kwangethuba kunye neengxaki zempilo yolusu. I-Titanium dioxide inika ukhuseleko oluncinci lwe-UVA ngoko uza kubona i-zinc oxide rhoqo kuluhlu lwezithako ze-suncream zeminerali.
Ikhuselekile kwaye inobuhlobo nokusingqongileyo – izithako eziphambili kwiikhemikhali ezininzi ze-suncream zinokuba yingozi kwizilwanyana zaselwandle nakwiindawo ezihlala emanzini ngelixa izithako eziphambili ze-mineral suncream zihlala zicingelwa ukuba zinobuhlobo nokusingqongileyo kwaye azinakubangela ukumhlophe kweekorale okanye zichaphazele ubomi baselwandle.
I-zinc oxide inxulunyaniswa neenzuzo ezininzi zempilo - Ingathomalalisa ukurhawuzelelwa (ingcono ukuba ukhe watshiswa lilanga kancinci), ayizukufaka iimbobo kuba ayinayo i-comedogenic kwaye iipropati zayo zokulwa neentsholongwane, zokulwa nokuvuvukala zinokugcina ulusu luthambile, ukubonakala kwemibimbi kwaye incede ukulwa namabala.
Siyathemba ukuba le bhlog ibe nengqiqo kwaye ikunceda uqonde umahluko phakathi kweemveliso ezahlukeneyo zokukhusela ilanga ezikhoyo.
