Maitiro e squalene oxidation ari pakuti nguva yayo yakaderera ye ionization inogona kupa kana kugamuchira maerekitironi pasina kukuvadza chimiro chemamorekuru emasero, uye squalene inogona kugumisa chain reaction ye hydroperoxides munzira ye lipid peroxidation. Zvidzidzo zvakaratidza kuti peroxidation ye sebum inonyanya kukonzerwa ne singlet oxygen, uye singlet oxygen quenching rate constant ye squalene mu human sebum yakakura kupfuura yemamwe lipids muganda remunhu. Zvisinei, zvinofanira kucherechedzwa kuti kunyangwe squalene ichigona kudzivirira lipid peroxidation, zvigadzirwa zve squalene, zvakaita se unsaturated fatty acids, zvinewo mhedzisiro inotsamwisa paganda.
Squalene peroxide inogona kuita basa guru mukukonzera mapundu. Mumienzaniso yekuedza yemhuka, zvakaonekwa kuti squalene monoperoxide inonyanya kukonzera mapundu, uye huwandu hwe squalene peroxide hunowedzera zvishoma nezvishoma kana uchipiswa nemwaranzi yeUV. Nokudaro, zvinokurudzirwa kuti varwere vemapundu vanofanira kungwarira dziviriro yezuva, uye mafuta ekudzivirira zuva anogona kudzivirira squalene peroxidation pahuwandu hwemuviri hunokonzerwa nemwaranzi ye ultraviolet.
Muchina wekuongorora gandainogona kushandiswa kuona kushanda kwekirimu yezuva. Mufananidzo weUV unoratidzwa bhuruu rakasviba kana pakaiswa kemikari yekudzivirira zuva; kana pakaiswa ganda rezuva, mufananidzo wacho unopenya, zvakafanana ne fluorescent residue.
