Mehanizam oksidacije kvadrata nalazi se u tome da njegov nizak period ionizacijskog praga može donirati ili primati elektrone bez oštećenja molekularne strukture ćelija, a kvarca može prekinuti lančanu reakciju hidroperoksida na lipidnom peroksidacijskom putu. Studies have shown that the peroxidation of sebum is mainly caused by singlet oxygen, and the singlet oxygen quenching rate constant of squalene in human sebum is much larger than that of other lipids in human skin. extinction constant.
