Squalene Depletion in Skin Following Human Exposure to Ozone under Controlled Chamber Conditions

Shen Yang

A major component of human skin oil is squalene, a highly unsaturated hydrocarbon that protects the skin from atmospheric oxidants. Skin oil, and thus squalene, is continuously replenished on the skin surface. Squalene is also quickly consumed through reac ...
