Ama-sunscreens angokwenyama, awaziwa kakhulu ngokuthi ama-sunscreens amaminerali, asebenza ngokwakha umgoqo womzimba esikhumbeni osivikelayo.imisebe yelanga.
Lawa ma-sunscreens ahlinzeka ngokuvikela okubanzi ngokubonisa imisebe ye-UV kude nesikhumba sakho. Ziphinde zisize ekugwemeni ukulimala kwesikhumba okuhlobene ne-UVA, okuhlanganisa i-hyperpigmentation kanye nemibimbi.
Ama-sunscreens amaminerali angasiza futhi ukuvimba imisebe ye-UVA engena ngamafasitela, engabangela ukuvela kombala nokuwohloka kwe-collagen. Yingakho kubalulekile ukugqoka i-sunscreen nsuku zonke, ngisho noma ungahlelile ukuphuma ngaphandle.
Iningi lama-sunscreen amaminerali akhiwe nge-zinc oxide ne-titanium oxide, izithako ezimbili ezibonwa njengeziphephile futhi zisebenza ngempumelelo yi-Food and Drug Administration (FDA)Trusted Source.
I-Micronized zinc oxide noma izikhilimu zelanga ze-titanium - noma lezo ezinezinhlayiya ezincane kakhulu - zisebenza njengazoama-sunscreens amakhemikhalingokumunca imisebe ye-UV.
“Ama-sunscreen e-Zinc oxide avame ukutuswa kubantu abangezwani nesikhumba, okuhlanganisa nezinduna, futhi athambile ngokwanele ukuba angawasebenzisa ezinganeni,” kusho u-Elizabeth Hale, MD, udokotela wesikhumba oqinisekisiwe webhodi kanye nosekela-mongameli we-Skin Cancer Foundation Trusted Source.

Zonke izinzuzo, ngokuqinisekile, kodwa ama-sunscreens amaminerali ane-downside eyodwa: Angaba ne-chalky, kube nzima ukusabalala, futhi - ngokugqamile kakhulu - athambekele ekushiyeni i-cast emhlophe ebonakalayo esikhumbeni. Uma unebala elimnyama, lokhu kusasiswa okumhlophe kungabonakala ikakhulukazi.Nokho, nge Unipromaizihlungi ezibonakalayo ze-UVunqobile'anginazo izinkathazo ezinjalo. Ukusabalalisa kwethu usayizi wezinhlayiyana ezilinganayo kanye nokucaca okuphezulu kunikeza ifomula yakho isigaba esiluhlaza okwesibhakabhaka esihle kakhulu kanye nenani eliphakeme le-SPF.
