I get wicked acne from PG. It took me several months to figure it out, because everyone kept telling me they were just "quit zits" from quitting smoking. But, I later discovered that that is impossible, since we are not actually going through nicotine withdrawals that would cause this. Vapers don't get "quit zits" unless they drop to zero nic. Also, I had found a VG juice that I liked, and the acne went away after a week or two.
I recently ordered a small bottle of a flavor that I like and asked for 10% PG just to see if that small amount would be okay. I vaped it now and then for a few days, and the acne came back with a vengeance. Back on VG-only now, acne gone.
So, the bad news is, you will probably have to give up PG to keep the zits away. The good news is, there are tons of amazing vendors who offer fantastic flavors in VG-only. Highbrow, Alien Visions, and Virgin Vapor are just a few. Get a small bottle of PGA to keep on hand, if you find that a juice you like is a little to thick for good carto performance, thin it out with a few drops of the PGA. Otherwise, I am a big proponent of dripping on atties rather than cartos - the flavor and vapor production is through the roof in comparison to cartos! And, it's really not that inconvenient, it only takes a few seconds to drip when you need, no more trouble than it was to grab a match and a cigarette before you made this smart move. ;-)
