Hi, I was on the forum a while ago when I started vaping. I started out with greensmoke, and then switched to the 510 types. I have a question I am wondering if anyone can help with. When I vaped, I started getting terrible skin, and not quit zits either, really sore spots on my back and face. I started the analogues again because they were blinking awful to cope with. I cant find a consistent answer online as to what the likely candidate is, PG or VG, and am wondering if anyone knows which is the likely candidate. It has been a while since i vaped, but fed up with smoking again it is time i stopped. I know everyones skin is different, but any pointers would be helpful. I was on 50/50 18mg juice and know i need to change the mix to almost all one or t'other, but which way to go? It took a few months the last time to show up if i remember correctly. Anyway, any advice, anecdotal or otherwise gratefully received. Bryan
