Recently a co-worker of mine had a rosacea like reaction which, he claims to be caused by either poorly made juice or the propylene glycol. He recently found a vendor in San Fran that offers 100% organic VG/H2O liquid. Since switching the "rash" has decreased but is still problematic. I know there are those out there with PG allergies but his reaction is localized to his face, specifically around his nose. Anyone else heard of this or has had the same reaction?
