1. Ndifanele ndihlawule malini kwi-SPF?

Ingcali yesikhumba eNew York uFayne Frey usikhumbuza ukuba “akukho thambiso lokuzigcina kwilanga olusebenza ngeepesenti ezili-100 ukuthintela ukutshisa nokonakala kolusu.” Ukwaphawula nokuba i-sunscreen “inokunyusa ixesha onokuba ngaphandle.”

Kwaye ixesha elichithwe ngaphandle lihambelana noko ne-SPF.

Uphando lwamva nje lubonisa ukuba i-SPF 100, xa ithelekiswa ne-SPF 50, yenza umahluko wokwenyani ekukhuseleni ulusu lwakho ekonakaleni nasekutshisweni. Ubuncinci, uya kufuna i-SPF 30.

UFrey wongeza ukuba ii-SPF eziphezulu zihlala zithe nca, ke abanye abantu abazithandi kakhulu. Kodwa olo khuseleko longezelelekileyo kufanelekile ukuba lube lolwandle, nokuba awufuni kulukhetha yonke imihla.

Ukuphinda wenze kwakhona: "I-SPF 30 yeyona ubuncinci ndiyincomayo, kodwa ephezulu ihlala ingcono," utshilo uFrey. I-Thinkbaby SPF 30 Stick ($ 8.99) igubungela iziseko ngaphandle kwemvakalelo efana ne-gluel. Kwaye intonga yenza ukuba iphinde isebenze ngokulula ekuhambeni.

Olu luhlu lwee-sunscreens zidwelisa into ye-PA, umlinganiso wokhuseleko lwe-UVA olususela ku "+" ukuya ku "++++." Inkqubo yokulinganiswa kwePA yaveliswa eJapan kwaye iqala ukubamba apha eUnited States.

UMonique Chheda, ongugqirha wesikhumba waseWashington, DC, wongeza athi "ngesiqhelo izithako ezibini ezibonelela nge-UVA yi-avobenzone kunye ne-zinc oxide, ke ngokuqinisekileyo ufuna ukuqinisekisa ukuba i-sunscreen yakho inayo."
