Njira ya squalene oxidation yagona kuti nthawi yake yotsika ya ionization imatha kupereka kapena kulandira ma elekitironi popanda kuwononga ma cell a cell, ndipo squalene imatha kuletsa machitidwe a hydroperoxide munjira ya lipid peroxidation. Kafukufuku wasonyeza kuti peroxidation ya sebum imayamba makamaka chifukwa cha okosijeni wa singlet, ndipo kuchuluka kwa mpweya wa squalene mu sebum ya munthu kumakhala kokulirapo kuposa kwamafuta ena pakhungu la munthu. kutha kosalekeza. Komabe, ziyenera kukumbukiridwa kuti ngakhale squalene imatha kuletsa lipid peroxidation, zinthu za squalene, monga unsaturated fatty acids, zimakhalanso ndi zotsatira zokwiyitsa pakhungu.
Squalene peroxide imatha kukhala ndi gawo lalikulu pakuyambitsa ziphuphu. Mu zitsanzo zoyesera za nyama, zatsimikiziridwa kuti squalene monoperoxide ndi comedogenic kwambiri, ndipo zomwe zili mu squalene peroxide zimawonjezeka pang'onopang'ono pansi pa kuwala kwa UV. Choncho, akuti odwala ziphuphu zakumaso ayenera kulabadira chitetezo dzuwa, ndi sunscreens akhoza kupewa squalene peroxidation pa thupi ndende chifukwa cha cheza ultraviolet.
Skin analyzerangagwiritsidwe ntchito kudziwa zotsatira za sun cream. Chithunzi cha UV chikuwonetsedwa buluu wakuda ngati mankhwala oteteza dzuwa agwiritsidwa ntchito; ngati dzuwa lakuthupi likugwiritsidwa ntchito, chithunzicho chikuwonekera, chofanana ndi zotsalira za fulorosenti.
