Iyo nzira ye squalene oxidation iri pakuti yakaderera ionization pachikumbaridzo nguva inogona kupa kana kugashira maerekitironi pasina kukuvadza chimiro chemolecular yemasero, uye squalene inogona kumisa chain reaction yehydroperoxides munzira yelipid peroxidation. Zvidzidzo zvakaratidza kuti peroxidation ye sebum inonyanya kukonzerwa neokisijeni ye singlet, uye iyo singlet oxygen yekudzima mwero we squalene mu sebum yemunhu yakakura kwazvo kupfuura yemamwe lipids ari paganda remunhu. kupera nguva dzose. Zvisinei, zvinofanira kuonekwa kuti kunyange zvazvo squalene inogona kuvhara lipid peroxidation, zvigadzirwa zve squalene, zvakadai seunsaturated fatty acids, zvinewo zvinogumbura paganda.
Squalene peroxide inogona kuita basa guru mupathogenesis yeacne. Mune mhuka dzekuyedza mhando, yakave yakasimbiswa kuti squalene monoperoxide yakanyanya comedogenic, uye zvirimo zve squalene peroxide zvishoma nezvishoma zvinowedzera pasi pe UV irradiation. Nokudaro, zvinokurudzirwa kuti varwere vezvipembenene vanofanira kubhadhara kuchengetedzwa kwezuva, uye sunscreens inogona kudzivisa squalene peroxidation pamagariro ehupenyu anokonzerwa nemirairo ye ultraviolet.
Skin analyzerinogona kushandiswa kuona kushanda kwezuva cream. Iyo UV mufananidzo unoratidzwa rima bhuruu kana kemikari yezuva yakaiswa; kana chemuviri chezuva chikaiswa, chifananidzo chinoratidza, chakafanana nemasara efluorescent.
