Clinical Procedures and Topics
Ozone decomposition by UV light leads to production of hydroxyl radicals and while this plays a part in the removal of hydrocarbons from the air it also creates peroxyacyl nitrates which are powerful irritants which compromise the skin.
Inhaled ozone has also been found to convert cholesterol in the blood stream to plaque (which causes hardening and narrowing of arteries). The powerful oxidizing properties of ozone may be a contributing factor of inflammation.
Although ozone was present at ground level before the Industrial Revolution, peak concentrations are now far higher than the pre-industrial levels, and even background concentrations well away from sources of pollution are substantially higher.
High frequency glass electrode beauty devices generate ozone.
Even low concentrations of ozone in air are very destructive. Exposure can produce headaches, burning eyes, and irritation to the respiratory passages.
Saccharomyces Ferment Filtrate Lysate is claimed to be especially protective against ozone. The ingredient is found in PCA Hydrating Serum, Replenix AE Dermal Restructuring Therapy PM, SkinMedica TNS Essential Serum and SPF 20.
"Ozone" originates from the middle nineteenth century from the German "ozon" from the Greek "ozein" meaning "to smell."
