\"\"Ochrana pred slnkom sa \u010dasto sp\u00e1ja s faktorom SPF, ten v\u0161ak v prvom rade ozna\u010duje ochranu pred ultrafialov\u00fdm \u017eiaren\u00edm typu B (UVB).

\u010co je to UVA \u017eiarenie?<\/h2>\n

Ultrafialov\u00e9 \u017eiarenie zo Slnka sa zvy\u010dajne del\u00ed na UVA a UVB \u017eiarenie.<\/p>\n

UVB \u017eiarenie je \u00fazko spojen\u00e9 so sp\u00e1len\u00edm od slnka a predstavuje hlavn\u00fd typ \u017eiarenia, ktor\u00fd sa meria pri ur\u010dovan\u00ed slne\u010dn\u00e9ho ochrann\u00e9ho faktora (SPF).<\/p>\n

UVA \u017eiarenie prenik\u00e1 hlb\u0161ie do poko\u017eky<\/strong> a prispieva k pred\u010dasn\u00e9mu starnutiu poko\u017eky<\/strong> a k jej dlhodob\u00e9mu po\u0161kodeniu<\/strong>. Podie\u013ea sa tie\u017e na procesoch spojen\u00fdch s v\u00fdvojom rakoviny ko\u017ee.<\/p>\n

Na rozdiel od UVB \u017eiarenia vystavenie UVA \u017eiareniu nesp\u00f4sobuje v\u017edy okam\u017eit\u00fa vidite\u013en\u00fa reakciu, ako je sp\u00e1lenie od slnka. Spotrebitelia sa preto m\u00f4\u017eu vystavi\u0165 zna\u010dn\u00e9mu mno\u017estvu UVA \u017eiarenia, bez toho aby si hne\u010f v\u0161imli jeho \u00fa\u010dinky.<\/p>\n

Preto by \u00fa\u010dinn\u00e9 opa\u013eovacie pr\u00edpravky mali poskytova\u0165 ochranu v \u0161irokom spektre ultrafialov\u00e9ho \u017eiarenia.<\/p>\n

Pre\u010do je testovanie na UVA \u017eiarenie potrebn\u00e9?<\/h2>\n

T\u00e1to norma stanovuje postup in vitro na charakterizovanie ochrany pred UVA \u017eiaren\u00edm u opa\u013eovac\u00edch pr\u00edpravkov. Je navrhnut\u00e1 tak, aby sa pomocou nej vytvorila spektr\u00e1lna absorp\u010dn\u00e1 krivka UV \u017eiarenia, z ktorej je mo\u017en\u00e9 vypo\u010d\u00edta\u0165 pr\u00edslu\u0161n\u00e9 parametre ochrany pred UVA \u017eiaren\u00edm.<\/p>\n
