I've been experiencing moderate/severe acne (I'm 62!) for over a year now. It is confined to my lower cheeks & jaw areas - where the straps from my mask are. I have covers for the straps, am seeing a dermatologist, taking antibiotics, using topical sulfur meds and still it continues. Is it possible that my SoClean could be causing it? I am putting the complete head gear with strap covers in the unit.
