Hi North Star
I can't say I agree with that statement with the possible exception of a person being allergic to olive or whatever ozonated oil is used. My wife has used ozonated oils daily on her face at night for over ten years. She does this about a half-hour before retiring and does not wipe it off. I would not say she applies it liberally though. Her face is softer and more pliant at 58 than many 30 year old women we know.
