I've been having the same thing going on. I haven't come to any particular conclusions yet, but it is improving. Thinking it maybe all PG juices, I started diluting them with some VG. Of course that diluted the flavor some, but was OK. All the new juices I buy have a lot more VG in it. If it's all PG, I don't buy it. I may end up going to all VG before I'm done. Started making sure I washed my hands more often to remove any juices from my hands & touching my face, which I do more than think. Just rinsing off my mouth area every so often seems to help. I think my lips get the worst from occasionally taking a drag and getting a little juice in my mouth from the cart. I use a chapstick/lip gloss a lot to help with dryness. It might also be caused from our bodies detoxifying from all the garbage that in analogs. I don't have any idea how long for all those toxins to completely leave our bodies.
I've been a heavy water drinker for many years, so think I'm OK there. Yesterday I was talking the guy at a health food store. He said one of the best things for hydrating is to drink at least 1/3 bottle of Gatorade a day in addition to water. I'm not wild about the the stuff, but may force myself to do that.
Maybe I'll get it figured out someday, but I'm not going to give up on vaping because of it. There's probably not one single answer that works for everyone, but I keep trying to come up with some kind of answer. You might want to talk to your pharmacist & ask what he'd recommend. There may be some OTC that may help.
