Isambulela sesimo sezulu sonke siyi-sunscreen.Ziningi izambulela ezigoqayo, kungakhathaliseki ukuthi lina noma ilanga singasetshenziswa.Ngakho-ke, ingabe kukhona ingozi ekusebenziseni isambulela sesimo sezulu sonke?Ngokuvamile akunjalo.
Isihluthulelo sokuvikelwa kwe-UV sincike kwindwangu yesambulela ephathwa nge-UV.Ukuvikelwa kwe-UV kwanele.Ngokuphambene, umphumela mubi.Nokho, kunezimo ezikhethekile.Isibonelo, nakuba kungekho ukwelashwa kwe-UV, kune-vinyl.Kodwa umphumela wayo wokulwa ne-ultraviolet uphakeme kunemikhiqizo evamile.Uma indwangu iyikhwalithi enhle, inkomba ye-UV ingafinyelela ku-600+ futhi izinga lomthunzi licishe libe ngu-100%.Uma uthatha isambulela, sivule ukuze ubuke ithunzi eliphansi.Amathunzi amnyama.Kuphela uma i-UPF (i-ultraviolet protection factor value) ingaphezu kwama-30 futhi ukudluliswa kwe-UVA (UVA) ingaphansi kuka-5% kungabizwa ngokuthi umkhiqizo ongazweli ku-UV.Izinga lezinga lokuvikela lithi "UPF30 +";Uma i-UPF ingaphezu kwama-50, ikhombisa ukuthi umkhiqizo unokuvikela okuhle kakhulu kwe-UV.Izinga lokuvikela limakwe ngokuthi "UPF50 +".
